I upgraded from a 29 gallon w/ 1G HOB fuge - to a 45 gallon with 20L sump. At first the transition went ok corals had color and were still growing. It has been about a month- 2 months and at this point it seems like everything is going down hill. I'm getting close to loosing sps frags / small colonies i've been growing out for close to a year. I just can't get the chemistry right and it's quite bizarre. If I get the alk and ca balanced alk around 10, ca at say 450. 10 hours later my alk is barely at 6, it will not hold and neither will my mag levels. I've tried adding vinegar to my kalk stirrer (avast K1), I've tried keeping the kalk changed out more often, I've tried water changes (50%). Nothing is working and the problem keeps getting worse.. I'm not super new to the hobby and my last tank had perfect water chemistry.
edit, need to add one thought. I have been blowing through ca and alk, my tank tanks a very large amount to make detectable adjustment. The amount suggested on the label never even registers when testing.
