Salinity: How to Measure and Why It's Important




Keeping an accurate salinity level in your saltwater aquarium is crucial to the health of your aquatic friends. Today we are going to explain why it is so crucial to keep a stable salinity level and show you the easiest and most accurate ways to monitor the salinity in your tank.

The "saltiness" or salinity is most commonly measured by specific gravity, which is a somewhat complicated unit of measure that has to do with measuring the density of the saltwater. You will also sometimes see it measured as PPT or part per thousand but, for all intents and purposes, we are going to reference Specific Gravity measurements throughout this video as it is the widely accepted unit of measure in the aquarium industry.

Corals require a stable salinity in the range of 1.023-1.026 specific graving. Most of the fish found in a reef tank are a little more tolerant compared to corals and can handle levels being maintained between 1.020-1.026.


Saltwater fish have a lower salt level inside their body than their surroundings. Because fish are constantly drinking saltwater, they have to actively regulate their internal salt levels which is called osmoregulation. Fluctuations in salinity make the fish have to work much harder to regulate the salinity of the water inside their bodies which in turn causes stress. When keeping corals and invertebrates, it is all that more crucial to maintain a stable salinity level because they are even more sensitive and fluctuations can easily cause them to perish.



In order to maintain salinity levels, many hobbyists will manually top off the aquarium with freshwater on a daily basis which does a sufficient job. After a few months of keeping a reef tank, most hobbyists invest in an automatic top off system (ATO) that adds freshwater to the aquarium multiple times each day to help maintain a stable salinity.

Measuring your salinity level should be done weekly, or at least every time you perform a water change—both before and after changing out the water.


The tool that most beginner hobbyists are familiar with is the swinging arm hydrometer. They are extremely inexpensive and extremely easy to use. However, they can also be extremely inaccurate. Salt crystals, calcium build-up and even air bubbles can cause a hydrometer to provide inaccurate readings. If you are using a hydrometer, we strongly recommend that you check the accuracy periodically with a more accurate device like a refractometer, which we will discuss later in this article.



Another quick and easy tool for measuring salinity is the floating glass hydrometers. The advantage is that they are more accurate than swinging-arm hydrometers and readings will not typically drift or change as the unit is used more and more. The disadvantages to floating glass hydrometers are that they are quite fragile and measurements can be difficult to read because of the small scale.


The best option for measuring salinity is a refractometer, such as the Marine Depot Refractometers or Red Sea Seawater Refractometer available on our website. It is a very simple tool to use and is extremely accurate. A refractometer utilizes a prism and light refraction to measure salinity; different salinity levels causes the light to refract differently.



While they are a bit more expensive compared to hydrometers, they are well worth the investment. A refractometer is very easy to calibrate, can last a lifetime if stored and used properly, and will provide you with quick and accurate salinity level readings each and every time. In fact, Marine Depot staff members prefer the use of refractometers over any other salinity measuring device. I am sure many of you hobbyists out there will agree.

Lastly, we have digital salinity meters and monitors which are great for those of you who love high-tech equipment.



Milwaukee and Hanna both offer a digital refractometer which will give you a digital salinity read out by simply placing a couple of drops of water on the meter. Just like an analog refractometer, these digital units are very easy to use and calibrate.



Conductivity monitors are also a handy way to electronically measure salinity. These monitors measure the electrical conductivity of the water which changes with fluctuating salt levels. The Neptune Systems Apex and many other leading aquarium controllers can allow you to continually monitor and record your aquarium's salinity level via conductivity.

With an option for just about every level of hobbyist, there really is no excuse to have fluctuating or improper salinity levels in your aquarium. Eliminating one possible stress factor to help keep your fish and corals healthy will surely help you on the road to building a flourishing reef.

Advanced Dosing: Beyond Calcium and Alkalinity




The evolution of a reef hobbyist is quite predictable.

Most of us start out keeping a small to medium sized tank with a few fish. After months of research and frustration, we soon learn the ins and outs of proper marine aquarium husbandry and more often than not an infatuation with collecting corals quickly follows.

This is when the real fun begins because you will start to understand the importance of proper water flow and lighting, get your hands on some really cool cutting edge aquarium equipment and learn more about water chemistry both in your aquarium and in wild ocean reefs.

After keeping a mixed reef tank for some time, most of us become familiar with maintaining the major elements: calcium, alkalinity and magnesium. However, there are plethora of other supplements available for your reef tank. Knowing which additional supplements you should use and why can get confusing and getting good advice can be tricky.

This brings us to the topic of today's article/video, "Advanced Dosing." We are going to cover some of the more advanced reef aquarium supplements, beyond calcium and alkalinity, and help you understand why you might consider using them in your reef.


Using Strontium helps stony corals and other reef building invertebrates grow and produce aragonite. As corals build their aragonite skeletal structure, they will consume strontium. Corals have in fact been witnessed to increase growth rates when strontium is maintained at levels found in natural seawater which is 8 ppm.




Potassium is most commonly used specifically for SPS corals and is known to help increase blue and purple coloration in some SPS. Potassium plays an important role in the creation of aragonite and will be depleted by corals and other organisms found in a reef tank. It is also widely used alongside various filtration methods employed to maintain ultra-low nutrient reef tanks in which potassium is depleted at increased rates.




Boron similar to potassium is important to the creation of aragonite shells and skeletons and will help improve red coloration within your corals.




Iodine is beneficial in a number of ways and is utilized by many soft corals, gorgonians, macro-algae and clams. It helps prevent coral bleaching because it will protect the tissue of photosynthetic corals under intense lighting and in periods of rapid growth. Iodine is easily removed via filtration and quickly consumed by corals, so it is recommended to add iodine 2-3 times per week. But be very careful, some iodine supplements like Lugol's Solution are very concentrated and overdosing can crash your tank.




Iron is most helpful in systems containing a refugium with macro-algae and other marine plants, such as mangroves. It promotes lush growth and deep green coloration. With increased macro-algae growth, you can boost the benefits of your refugium via increased nutrient export and protection against nuisance algae outbreaks.




When dosing Vitamin C, many hobbyists have reported favorable changes when keeping zoanthids and paly colonies. It is most commonly used to boost immune systems and supplement fish food, but has also been shown to help the growth of soft tissue, so it is great for helping freshly fragged corals to recover and grow.




Amino Acids are rapidly becoming more and more popular and used by many hobbyists and even culturing facilities to help increase coral growth. Amino acids provide the protein needed for corals to build and repair tissue and will also encourage vibrant color within your coral.



The aforementioned aquarium supplements can really take your reef tank to the next level. Just be sure you are testing your water parameters frequently and always be conservative when starting to add new supplements to your tank because rapid changes in water chemistry can be disastrous for your reef. Supplementing your reef with coral food is another great way to give your corals that extra edge.




Phytoplankton is at the bottom of the food chain and is great for a number of reasons. It will increase biodiversity in your tank as it feeds a number of micro-organisms in your tank helping to create natural food sources for corals and other reef tank inhabitants. It can also be directly consumed by many corals and clams.




Zooplankton is a bit larger in size and is on the next level in the food chain compared to phytoplankton. The larger particles are great for soft corals, LPS corals and many other filter feeders.




Marine Snow type products replicate the important organic food particles that fall from the light rich shallow reefs and supply a critical food source for filter feeding organisms found deeper in the water column. Particle sizes range from very small (under 20 microns) up to 150 microns. It is therefore a great way to offer food for your entire reef via a single additive.

The benefits of properly dosing a reef tank can really be the difference between an average mixed reef and a flourishing explosion of aquatic wonder!

How to Build a Saltwater Mixing Station




Every aquarium needs water.

For saltwater aquariums in particular, it is of utmost importance to use PURE filtered water to mix your own saltwater and replenish what is lost from evaporation.

To make these regular aquarium chores easier, today we are going to show you how to build and set up your own saltwater mixing station. We did not have much space to work with in our office, so if you are lacking space in your garage, this may be the perfect solution for you.



To complicate matters, we have pretty lousy tap water quality and water pressure at Marine Depot's headquarters in Garden Grove, CA. Our water pressure is low, averaging about 40 PSI and our Total Dissolved Solids are high, running right around 400 on the TDS meter.

These unfortunate circumstances make it more difficult for a reverse osmosis deionization system to run efficiently and effectively. There is not enough water pressure to push the clean water through the TFC membrane and the dirty water clogs up membranes resulting in lower production levels.



To combat this perfect storm of problems, we decided to use our new KleanWater 6-Stage Advanced RO/DI System along with an AquaticLife Smart Buddie Booster Pump. A 6-stage system will lower our high TDS level so we can get the most out of our TFC membrane. The booster pump will restore the water pressure our RO/DI system needs to produce pure water at optimal rates.

Since our tap water also contains chloramines, we decided to switch out one of the carbon block filters with the Marine Depot Chloramine-X GAC Carbon Filter which has a higher capacity for chloramine removal.

The KleanWater Advanced System we are using for this application features a pressure gauge so we can monitor the performance of the pre-filters. It is also equipped with a triple TDS meter to monitor the input, RO output and the DI water. It also has a manual flush valve that extends the life and improves the performance of the TFC membrane. In our particular case, we are using the Smart Buddie Booster Pump—which has a convenient automatic flush feature—so the manual flush valve on the KleanWater system will be bypassed.



The Smart Buddie is, by far, the easiest booster pump to install. Every connection port is clearly labeled to make things super easy to set up. It also automates the typically manual tasks of flushing your membrane and shutting off the supply water. Once we installed the unit at our new saltwater mixing station, we were thoroughly impressed with its performance and the increased production we've gotten from our RO/DI system.

For our saltwater mixing station, we needed two separate containers: one for storing fresh RO/DI water and another for mixing saltwater. The problem was we were very limited on space. To solve this dilemma, we built a wooden stand out of 2" x 2" and 2" x 4" pieces of lumber. Once we constructed the stand, we applied a coat of black paint to protect the wood from water spills.



We used a rectangle-shaped 20 gallon Clear-For-Life acrylic aquarium and placed it on top of our DIY stand to store our product (purified) water. We installed a float valve at the top of the tank to work with our booster pump to keep the tank filled with ready-to-use RO/DI water. The water shuts off automatically once the aquarium/reservoir is full.

Beneath our freshwater container tucked inside the stand sits a 20 gallon Rubbermaid Brute trash can on a dolly. This is where we'll mix our saltwater, which can easily be wheeled around the office to our fish tanks to perform water changes. The gray Rubbermaid Brute trash can we chose is made of heavy-duty plastic and is NSF Certified, so the likelihood of it leaching unwanted chemicals into your water is greatly reduced.



We installed a bulkhead on the bottom of the Clear-For-Life aquarium and attached some flexible vinyl tubing and a ball valve. This allows us to quickly and easily fill our Brute or top-off containers as needed. We also placed an aquarium heater and a powerhead inside the Brute for mixing our saltwater and bringing it up to the proper temperature.

By having a convenient and efficient water station at home, you will save yourself a lot of time, money and hassle. You are also more likely to keep up with a regular maintenance schedule which will hopefully result in a vibrant, thriving reef aquarium. Our saltwater mixing station only took a couple of hours to install, but now that it's finished, we can confidently share that it has definitely been worth the effort. Our fish and corals have never looked better!
