I got some corals recently and acclimated to a 40 gallon, currently, the phosphate is at .51 ppm and nitrates at about 20 ppm (high -_- but the price I pay for using an api test prior to a hanna) oddly....my xenia and firework polyps seem extremely unhappy and haven't opened up since I got them and kinda flop over, yet the Favia, Birdnest, Montipora are happy? I can't figure out what the deal is. Does anyone have some advice? Also, a good way to lower my phosphates without shocking everything (did remove some dry live rock which I think was the culprit for raising phosphate so high)
