I agree about not changing the sponge out, but the bio-media should be changed out as the pores become clogged over time with algae, slime, and gunk. The bio-media that comes with the aquaclear supports both anaerobic and aerobic bacteria (anaerobic occuring deep within the media balls, aerobic...

I have been experimenting using a BRS GFO reactor on my 12 gallon minimally planted tank for about 2 months now (bigtime overkill I know, lol). I plan on moving this reactor over to my saltwater tank once I get it set up, but for now I'm just playing around with it. I have read mixed opinions...

Interesting. I used Tetra Safestart in the past and that stuff was great - cycle completed almost overnight! I was really impressed. Part of me doubts that Seachem would knowingly sell a defective product, so maybe I'll give it another shot in the future.

Simple question: Do you need to continuously use this stuff in order to maintain your biological filter? I assume since it's bacteria, they reproduce on their own and the system is self-maintaining. However, the bottle says to add a capful every month for "optimum performance". I don't know if...

The API kit will test both ammonia (NH3) and ammonium (NH4+), so if you're getting a reading on your API kit, it could very well be indicating both NH3 and NH4+ are in your water. There is one tester I know of that tests for NH4+ exclusively and that's the Seachem Ammonia Alert. I suppose if...

Fluval Underwater Filters are completely submersed in water, and are therefore completely silent. Very pleased with mine.

For anyone looking to purchase (or who already owns) this reactor, I found out that braided vinyl tubing (1/2 inch) works really well with the quick connect fittings. I bought this reactor about two weeks ago and found out that the polyethylene tubing it comes with is super stiff and difficult...

Is there a particular light, and/or spectrum of light you guys can recommend to inhibit algae growth? I'm running two non-planted freshwater tanks (both 12 gallons), with 6400K CFL lights. Thanks!

It's best to condition the water before it reaches the tank. It's actually pretty easy... 2 drops per gallon, so for a 10 L bucket (2.64 gallons), just add 6 drops and you're good to go.

That might make it in to my signature line for work! :D

Aqua clear for the easily maintainable filter basket. The only downside is that they are quite noisy the first few weeks.

Nice tank! What lighting are you using?
