You could try using some chemipure blue in the sump area. No reactor needed. Just place it in a high flow area. It is a combo of carbon and phosphate remover. It works pretty well and should be able to help lower your phosphates. If you can, do some manual removal of the GHA and “up” your clean up crew. I would also stop feeding reef roids. They are loaded with phosphates. Only a minimal amount is needed. If you still want to use, I would wait until you get your phosphate within your specific desired range first. Also remember to monitor your corals health vs. shoot for a certain number.Hey guys, so my tank currently has really high phosphates.. eek!! So I've been noticing some nuisance hair algae growing on my rocks and I wasn't really sure why, so I decided to finally invest in the phosphorous hanna checker (the one that measures in ppb). I then checked my water, and apparently my phosphates are around 0.6ppm!! I'd like them to be around 0.03ppm so I can get decent coral growth, especially for my SPS I currently have.
I have a 29 gallon biocube, and I'm currently using PhosGuard in a bag in my refugium. I use about 50mL of the stuff every couple of days, just as the instructions say. The problem, however, is that my phosphates haven't really lowered. The checker still says that it's 0.6ppm despite me using PhosGuard (and I know it's not the checker because I checked a buddy of mine's tank water too and they got a lower reading than I did).
I've been looking into possibly getting rowaphos, but I read that a reactor is recommended for it. Is it worth getting a reactor just to use rowaphos? Or what do you guys recommend for my phosphate issue?
As an added note, I think my phosphate issue may be coming from my feedings. I have a blue-eyed anthias that I've been feeding in the tank 2x a day (mysis, brine shrimp, flake, pellets), as well as my corals I feed reef-roids to every Thursday. In addition, I dose 12 drops of Brightwells CoralAmino every Monday and Friday. So with all this, I need a good phosphate remover to keep up with the nutrients I'm adding into the tank.
Any suggestions are highly appreciated!
