ALk is really high

[Skimmerking]

Well My tank alk is at 14.2 DKH, and Doug and I have been having trouble understanding why its doing that. when I was gone away doug was looking after my tank and he tells me that the tank was at 8DKh when he was doing his water changes. I thought it would be from the IO salt having a super high level of 22DKH from the past. But Doug has been checking the water in the bucket and the tank and its not that. So I have been using pickling lime to top off on a float switch for evaporation. Its getting to the point that the kalk and the RO/DI water is getting really weak from the Pickling lime its hardy any in there.

Doug has been doing regualr water changes 5-15 gal every other week. I'm stunned on what it could be. The CAL is at 450PPM I'm waiting for my Phosban reactor to show up may be that it will lower the ALk in the tank and that will help it out. Other then that Im lost for what I should do.
