So I've Had My Tank Running For About 4 Months Now. Its A 180 Gallon Reef Tank In The Making...i Have A Phosphate Reactor And I Just Put In A Media Bag Of Phos Ban Into The Sump. What Can I Do For My Phosphates To Come Down Faster Since Some Of My Corals Are Turning Brown. If I Did A Large Water Change Would That Bring Down My Phosphates?? Thanks For Anyones Knowledge.
