High Alkalinity in 29g biocube, Anyone else with problem?

[menroxxy]

I was just wondering if anyone else is having an alkalinity problem with their 29g biocube. Mine is extremely high. Right now it is at 14dkH. I have reduced it w/water changes and stopping supplements. But as soon as I get it back down and start supplementing again, it starts creeping right back up. Everything looks great in the tank. All other parameters are on key. Just was wondering if anyone else was having this problem?

The problem is probably not related to the biocube, but rather your dosing scheme. If there is not enough uptake by the corals of Ca and Alk, they will collect in the tank and gradually rise. For your situation, water changes may be enough to keep your Ca and alk in balance. Test for these first, then add supplements as needed. HTH
