Hopefully this topic hasn't been beaten to death but I feel like my alkalinity consumption is high for a 2 month old 29 gallon tank with about 10 lps corals and a couple mushrooms/zoas. I have gotten to the point today where I had to dose 38 ml of red sea kh/alk and it seems to change almost daily. The tanks ph is pegged at about 8.4 and all other parameters are looking good except for my nitrates that are about 30-40ppm. Is there something I am missing here or is this normal alk consumption for happy corals and coralline algae? As always thanks for the help!
