Phosphate problems and potential consequences?

[robbyville]

Hi all,

Last week when noticing some algae growth I finally got off my tush and did some phosphate testing. Using a salifert kit it looks like I am hovering around .25 which according to my instruction book is worse than critical and means coral growth retarded which also might explain a few things in my tank.

I have put some Kent phosphate sponge into my prism pro media basket and after 2 days testing seems to be roughly same amount. Any thoughts on how I can bring these levels down?

Thanks,

Rob
