Hello all,
I've been dosing 2-part in my systems for years with no issues... until recently. The past several months my tank has gone from stable one week to crazy alkalinity and calcium fluctuations the next with notable precipitation in the substrate around the rocks and near the waterline on the glass.
I've done loads of research and read several of Randy's articles, but can't pinpoint my issue. I've calibrated my dosing pumps, stopped dosing for several days to measure the drop in Alk (measured 1.3 dkH drop which feels high considering the tank is lightly stocked) and Ca only to restart the dosing pumps at the proper amount and have the levels continue to fall. I've programmed the dosing pumps to ensure they don't dose at the same time and even installed a small powerhead aimed directly at the spot where the dose occurs and still no luck.
My pH runs between 8.1-8.3, measurements are taken via Trident, and dosing is performed via the DOS (auto dosing is not turned on).
The tank is about 40 total gallons and has significant coralline growth, but only four small(ish) LPS corals at this time.
Any help would be appreciated!
