Q&A with Keith, 2/26/10


QUESTION

I have an unusual amount of brown algae growing in my tank lately. Why?


ANSWER

Thank you for your question. Unfortunately you did
n't indicate whether it is leaf-like (brown macro algae) or slimy (coating the sand, glass and/or rock). But generally speaking, when there is an increase in algae growth in an aquarium it is usually a sign of an increase in organics, like phosphates and/or nitrates.

It may be a sign that the bulbs illuminating your tank are getting old and shifting in spectrum (learn more about how often to replace your bulbs). It can also be attributed to the water you are putting into your tank. Definitely check to see if your RO/DI system cartridges are due for replacement.

Now assuming nothing drastic has occurred in your aquarium tank lately (using a new brand of salt, adding several fish, a new or increased feeding regimen), I would begin by double-checking the water quality quality within the tank. Verify all pH, nitrate, phosphate, calcium, alkalinity (etc.) levels are right where they need to be.


If you aren't currently using a phosphate remover media (like RowaPhos or Phosban) , you might consider trying it for a few months to see if that makes any noticeable changes. Using a fluidized filter, like a Phosban reactor, is a great way to use these types of media in your tank.

If you've been a little lax with your wat
er change regimen—most of us are guilty of this from time to time—you may want to do a couple of extra water changes to get back on track.

If your
light bulbs are inching towards the end of their recommended lifecycle, consider slowly replacing them (the link above will more thoroughly explain what I mean by "slowly"). As bulbs age, they shift in spectrum and sometimes cause algae to grow faster.

If you make and mix your own water for top-off and water changes, try replacing your
reverse osmosis cartridges. Most hobbyists recommend replacing the sediment, carbon and DI cartridges every 6-12 months (depending on usage) and the RO membrane every 2-4 years (more info).

It's important to note that aquariums go through cycles of maturation, especially during the first 6-12 months. It's possible your tank is just going through one of these cycles if it's within that time range.


Additionally, I've spoken to many hobbyists who've experienced great success using supplements like Prodibio to help clear up algae outbreaks. Their aquariums not only have less nuisance algae growth but the corals have better coloration and growth.

Hopefully these tips will help you resolve your brown algae problem. If you've tried most of these solutions already and are still experiencing issues, please
contact us again so we can learn a little more about your system.

Reefer Gone Green!


“Who even likes fish?"


I asked myself this very question while cleaning aquariums back in May 2003 at my first job, a local pet store.


"I mean, they just float or swim side-to-side."


These feelings persisted during my first couple of months on the job. Then one day I observed a coworker feeding Oscars with some feeder fish. Whoa. Now this whole fish thing was getting interesting.


The following week my coworker took me to a true LFS where I got my first look at the cooler, more aggressive fish available. I also glimpsed a reef aquarium for the first time.


Suddenly, I was hooked.


Fast forward six years.


"Psh. Tetras? Lame!"


After years dabbling in saltwater aquaria, I had come to view freshwater tanks as somehow inferior. It wasn't until around this time last year that my mind was forever changed.


During my first week of employment at
MarineDepot.com, a veteran employee showed me pictures of planted tanks that completely blew my notion of freshwater tanks being second-rate out of the water.


Not only did they look good, many were better than the best reef tanks I'd seen. Suddenly those docile tetras were a thing of beauty, weaving in and out of plants and schooling. The scenes were like works of art. I squandered my breaks and lunch hours ogling photos and watching videos online.


I felt inspired. I immediately began hashing plans for my own planted tank.


Fast forward again.

The tank's been up and running now for four months and, I must admit, it's coming along pretty good. See for yourself: I've included a picture of my 46-gallon bow front with
this post.

I'd expected the planted aquarium side of the hobby to be more challenging than it has been. But believe me, I'm not complaining! It's just after maintaining aquariums personally and professionally for so long I guess I'd prepped myself for the worst. I've learned one of the keys of keeping a planted tank healthy—similar to reef aquaria—is having the right equipment.


I consider myself a low maintenance hobbyist. I don't dissect every detail and analyze every aspect of my tank.


When it came time to choose a substrate I didn't reach out to the scientific community or research the chemical properties of substrate. Instead, I asked my peers. I looked online. The consensus was a substrate rich in Fe (iron) was the way to go, like
fluorite or Eco-Complete. I opted for three 20lb bags of the Eco-Complete. It's a "live" substrate enriched with the essential elements that a planted tank needs to be healthy. I also buried Seachem Flourish Tabs in the substrate to help the plants' roots.


Before my foray into freshwater, I hadn't calculated the watts per gallon of my tanks. Now I can proudly share I've got
3.39 watts per gallon via a 4 x 39 watt Aquatic Life T5HO fixture. Speaking of the light, I am impressed by it in every way. It has a built-in timer that controls bulbs 1 and 3 separately from 2 and 4 and there is only one cord for the whole fixture. You can also control the lunar LED lights. Nice.

Next week I'll post a follow-up with a breakdown of my equipment along with some of the rookie mistakes I've made (and corrected) so you can learn from them.


And maybe, just maybe, I'll turn some of you reefers over to the dark side. Or, at least, the green side.


Until next time, stay classy.

Fish in our Reef Tank, Part 2: Genicanthus Angels—The "Perfect" Reef Angel?


I have kept many types of dwarf angels (Centropyge sp.) in my reef tanks over the years. While I love their color and active behavior, they also have their drawbacks.

Most of them picked at coral or, despite their, size were relatively aggressive. In particular I had an issue with Flame Angels. They seemed to love destroying my red Trachyphyllia brains. Most other corals were simply nipped at causing less polyp extension.

For my 120-gallon aquarium, I wanted to find an angelfish that was going to be actually reef safe (i.e. less aggressive and wouldn't pick at corals).

I began researching and asking other hobbyists what their experiences have been and if they had any recommendations for a reef safe angelfish. I discovered most feel there is no such thing as a reef safe angel. The closest are Genicanthus angels. There are 4-5 different Genicanthus angels readily available to the trade, including the Lamarck's angel (my choice), Swallowtail angel, Wantanbei angel, Bellus angel and Zebra angel.

Besides the reef safe factor, there were two other characteristics that drew me to these angels. First is their color. All are predominately blue, which just so happens to be one of my favorites colors. The second is that you can keep a pair in your tank. The differences between males and females are easy to identify, some being very different.

To find out more, I posed a question to Dr. Frank Marini about the angels on the Marine Depot Forums. He let me know that "Many Pomacanthidae are sequential hermaphrodites, and Lamarck angels are similar. With the fish determining as a female first -> then transitioning to a male when needed (termed protogynous.)".

I presently have a single Lamarck angel in my tank—a model citizen so far—and will eventually add a second in hopes of pairing them.

If you are looking for a reef safe angel for your tank, don't overlook the Genicanthus angels!

2009 Aquascaping Contest


"A beginning is the time for taking the most delicate care that balances are correct."

So begins one of the most beloved science fiction novels of all time. This is usually true, and yet in our new aquariums we often rush past the design phase to get water and fish in as soon as possible. Almost always, a few months down the road we end up staring at a tank that just looks a little off. By then, the system has plants and animals all over and is difficult to redo.

In the hobby, we refer to the creative design process as aquascaping.... like landscaping underwater. Like landscaping, a little ground cover with a big tree in the middle and some shrubs is functional, nice, and like every other house for miles around. If you'd like to have something phenomenal, you're going to have to take some time planning and think outside the glass box.

Enter the masters of aquascaping, whose extraordinary creations you can see in the annual aquascaping contest here. Take time to notice how they use the balance of positive and negative space, the contrast of colors, the ratio of sizes between objects to give the illusion of depth and space. See how different creative ideas, from sweeping plains to tropical jungles are recreated beautifully. Think about how some of these ideas can improve your own setup. Many saltwater hobbyists would skip this over, but I truly feel that most reef keepers out there could learn a lot from freshwater aquascapes.

Until next time, be like water...

Fish in our Reef Tanks, Part 1


Being a "reef nerd," fish have always been a second thought for my tank.

While planning past and current tanks, I find myself thinking more about what corals I want to keep rather than what fish I will get.

Only recently have I become fascinated by the fish in my tank and their unique characteristics. Their interactions with each other and their surroundings as well as their usefulness within the tank have become more and more intriguing to me.

Some may recall my 54-gallon tank build from previous posts (type "54" in the search box in the right column if you're unfamiliar). Well, that tank is now history: I've since upgraded to a 120-gallon aquarium. After relocating my orchid dottyback and pair of black & whie Ocellaris clowns I decided that all fish hereafter would be carefully considered before being added to the tank. No more impulse purchases.

Despite my best efforts--water changes, nitrates/phosphates at zero, refugium with cheato growing--I was having a nuisance algae problem. The liverock had a coat of red turf/hair-like algae growing on it. I knew my first round draft fish was going to help me deal with this problem.

I began researching algae eaters so I could choose the right prospect for my lineup. After digging through books and clicking through countless web pages I thought I'd found the perfect candidate: the Orange Spotted Rabbitfish. I purchased one and, lo and behold, he's done a fantastic job cleaning up the tank. 99% of the red algae is gone!

Equally impressive is his personality. When the lights turn on he is the first fish to greet me. His face and body language seem to say, "Look at me! Feed me!" Whenever my hands are in the tank for maintenance, he's a cool cat and could care less that I'm poking around in his habitat. I think he'd even let me pet him. Of course, with his venomous spines, that is not a risk I'm willing to take.

In my new post, "part two," I will recount my search for the "perfect" angelfish.
