High phosphates

[cocoacf]

I tested my water yesterday and my phosphates were a little high..
It's causing a head on one of my corals to contract a bit.
I have a 14 g biocube, is there anything I can do to lower the phosphate? (how much of a water change) I changed my filter.

high phosphates are caused by excess nutrients and if you use tap water to top off. I use seachem phosguard for my tank. put it the filter for 4 days and test again. it works pretty well.

SEACHEM PHOSGUARD or SEACHEM SEAGEL
works great.
