hi friends, im hoping someone can give me some torch/ hammer advice. my tank is a 125 gallon a few years old. my parameters are sal.-1.024, alk.-7.7, nitrates 13.7, phos. .19, cal.-451, temp. 77, ph 7.8.. why cant i keep these things alive?? im careful about the flow. par is 150. they can look so good for a couple of months, than just slowly shrivel up and disappear! i alternate with broadcast feeding them reefroids and benepets. id be so glad for some advice! i did dip them again and carefully inspect for pests. havent seen a thing. thanks!
