Q&A with Keith, 7/30/09


QUESTION

I have a 29 gallon saltwater aquarium. I have been told I need 2 powerheads for my tank. My question is, is it necessary to have 2 powerheads? Will one do the job? I am starting with fish only and will eventually segue to a reef with corals. What would be the ideal amount of live rock for this sort of setup?


ANSWER
The answer depends on the size of the powerhead(s) you choose to use.


A single large powerhead is not the best choice since it would create too much force in a single area of your aquarium. Although with a single properly sized powerhead, you could get away with using just one.


A large number of reef aquarium hobbyists opt for multiple powerheads to provide flow throughout the tank so there aren't "dead spots" where food and detritus can accumulate.


You should consider the
Hydor Koralia powerhead series for your setup. They produce gentle water movement at high flow rates and are extremely affordable. If you prefer a single pump due to space constraints or aesthetics, try the Hydor Koralia 3 or 4. If you can fit two, I suggest two model 2's or two model 3's or even one of each.

Most experienced hobbyists recommend 1-2 pounds of live rock per gallon of water. For your aquarium, aquascape your tank with 25-30 pounds and see how things look. Add or take away to your liking.

Q&A with Keith, 7/24/09


QUESTION

What does ORP stand for and how important is it to monitor?


ANSWER
ORP stands for Oxidation Reduction Potential. Measured in millivolts (mV), ORP is the measure of your aquarium water's ability to breakdown waste products.

Hobbyists running an
ozonizer with their aquarium system will keep a close eye on ORP. Others may never check it. It's a bit complicated so for brevity's sake, we'll give you a synopsis and if you want more info you can follow up with your tank specifics and we can better answer your question.

The best method to monitor ozone input is by measuring the ORP with probes or by a Redox meter/controller. The term Redox potential refers to the electrons transfer from one substance to another that takes place in every chemical reaction. The substance that receives electrons is said to have been oxidized, while the one that loses electrons is said to have been reduced.

In sea water, many of these so called ‘redox reactions’ occur simultaneously. Because of the constant exchange of electrons the amount of prevailing oxidative or reductive reaction can be measured as a voltage, by means of a platinum electrode and a volt meter. The higher the redox potential, the greater the oxidizing capacity of the water.

In sea water the redox potential is between 350-400 mV. Redox potential values of between 300 and 350 mV are recommended as the desirable level, which indicate an oxygen rich environment with low dissolved organics. The redox potential can therefore be used as an indication of the quality of your aquarium environment. Values below 200 mV indicate an accumulation of dissolved organics and a low oxygen level.

Q&A with Keith, 7/17/09


QUESTION

I have two
metal halide bulbs that are due for replacement. Is it better to use the same brand of bulb for both, or does that not really matter?

ANSWER
It is a matter of preference. I prefer using the same brand of bulbs over my own tank. Even if the Kelvin ratings are identical, every manufacturer's bulbs will produce slightly different colors.

If you were to run a 20K Blue Life bulb on one side and another brand on the other, for example, one may appear more blue while the other shines a whiter light.

You might actually prefer this look. Many do. I just prefer a more uniform appearance. There would be no harm in running two different brands of light bulbs over your aquarium.

Reef Necessities, 7/8/09


It's baaaack. That's right, another edition of Reef Necessities is here ... and just in time, too.

Summer is in full swing and we've been receiving a lot of questions lately from hobbyists asking how they can keep their aquarium temperatures stable during the hot summer months.

While
chillers and evaporators are always an option, they are also relatively expensive and thus not a one-size-fits-all solution. And while floating ice in your aquarium may be a quick fix, many hobbyists are seeking a more permanent, albeit inexpensive solution.

And what, pray tell, might that be? Since I'm probably going to post pictures after I finish writing this, I think you've already concluded it's a fan. Well, two fans, actually. Or four ... depending on your requirements.


Azoo's cooling fans are top-notch and extremely popular. So popular, in fact, that we can rarely keep the two-fan model in stock. But right now we've got both models available and, because our purchasing department apparently likes me, they've decided to drop the prices 20% after I told them I'd be writing a blog post about them.

Azoo fans produce very little noise and blow 10x more wind than a "common" fan. They clip right on your tank and are adjustable, providing a temperature drop of up to 4 degrees.


Here's a little customer feedback from the product reviews on our website.

"It lowered the temp in my tank in about an hour. Also when mounting the unit I accidentally dropped the whole unit in the water, totally submerged. I pulled it back up and worked fine." — Amit Rahman

"I accidentally left the fan off one day and my temps rose to 84 degrees. With the fans on, I have a steady 79-80 degree temp with no issues. I purchased the fan in lieu of a chiller due to the cost, taking a chance it would work with the strong light I have (sunpod 250W MH)." — Ryan Milo

"I wanted the Azoo fan year ago when I bought my JBJ Nano Cube, but I found an imitation that was ~$10 cheaper and bought that instead. Last month, the cheaper alternative seized up and allowed my tank to heat up to ~85 degrees before I noticed. I bought the Azoo and noticed how how much quieter and larger it was than the first one that I bought. Go ahead and get the real thing if you're in the market for one of these." — Brian
The price of the two-fan model has dropped from $29.99 to $23.99, and the four-fan model dropped from $49.99 to $39.99 (compare both here).

Q&A with Keith, 7/2/09


QUESTION
I want to start a copepod culture to prepare for a future mandarin goby purchase. Any tips?


ANSWER
One of the best ways to grow a copepod population is by setting up a
refugium. A refugium will provide your copepods an area free of predation so they grow and reproduce quicker.

If your refugium is large enough to accommodate live rock, place a few baseball to softball-sized pieces of live rock inside it. Every week or two, put your refugium rocks into your main/display tank. This will replenish your tank with copepods as a food source. Keep swapping out pieces of live rock every week or so.


You do not have to use a refugium to grow copepods. You can setup a separate, smaller tank with just live rock and no fish to grow and reproduce copepods. Just swap out the live rock on a regular basis for feeding as described earlier.

let us know! We're happy to help.
