alk levels ? just curious if i may have a problem.my calcium is at a steady 450,my ph is at a steady 8.5,my alkalinity however will not stay up.i'm using a red sea alk test kit and it only has 3 colors to choose from low0-1.6,normal 1.7-2.8,and high 2.9-3.6.ok so it reads at the low half of low and i checked it at the lfs and it was low when they tested it.i'm using seachem reef builder to raise carbonate alkalinity.it says half tsp per 40 gallons twice a week.i'm using an over full tsp 3-4 times a week to get it at a normal level.am i missing something?or will i just always need to add it?i've never had to deal with this before but some corals mainly lps were shrinking a bit.i have a softy,lps,and sps 55 gallon with a 29 gallon half full sump,plenum,skimmer,chaetto,and run carbon.
