I have been having a massive amount of green hair algae since I put new lights on my 20g long reef tank. I've had the new lights (CSL PC
's) for about 3 1/2 months now, so i was hoping to see some of this algae go away, but it hasn't. So a week ago I bought some macro algae to try an outcompete the microalgae. Halimeda and 4 shaving brush plants (Penicilus.sp).
I just got a Salifert Phosphate test kit and it is saying my PO4
are "critical" (.10ppm) to "coral growth retarded" (.25ppm) somewhere inbetween probably.
I've been using distilled water the entire life of the tank which is about 7 months along now. I tested the distilled and there was absolutly no PO4
in it...to my suprise.
I don't know how the PO4
got so high. I feed once or twice a day, flakes and mysis shrimp or brine shrimp all in small amounts.
I have a percula clown and a small domino damsel in the tank with two cleaner shrimp and corals and a clam. I also use DT's phytoplankton (only feeding once a week) and I add one ML of Coral Vital daily.
Im thinking about using some PO4
remover media in the media basket of my skimmer, (I usually have activated carbon running)
I've heard some bad things about PO4
remover especially with soft corals.
Does anyone know about PO4
removers? Will it be harmful to my tank inhabitants. I only have a couple of soft corals...mushrooms,button polyps, and a red chilli coral (Nephthyigorgia). All other corals are LPS
and one T. Derasa clam. Plus a clean up crew of crabs, snails.
Thanks for any help, and if there are particular brands of PO4
removers to use, or to stay away from, that anyone knows about, please let me know.
