Who Gives A Fish Forums

Thanks for the tips, everyone. Gonna start with GFO at half dose and cut back on feeding. My nitrates are at 10 ppm, alk's at 8 dKH, and I'm running Radions for 8 hours a day. Bulbs are about a year old—maybe time to replace 'em.

My tank's been struggling with high phosphates lately, and my corals aren't looking great. What's the best phosphate remover y'all have used? I've got a 75-gallon mixed reef with LPS and SPS, running a protein skimmer and carbon. Parameters are stable except for phosphates sitting at 0.15 ppm.
