Having problems with coral dying

[CrazyFishPeople]

Only level that's high is my phosphates. Best way to get them down & keep it there?

Run GFO through a media reactor

How high are we talking?
Where are you getting water for top offs and water changes?

 

[reefstarter]

Yep that will do it but what kind of corals? Most lps and softies won't care but sps will

I use lanthanum chloride for phosphate in my tank. It's an option if you don't like the clutter and expense of reactors and media.
