My Tank Thread
Wow, I'm shocked your tank is doing well with that kind of alk swing! If my math is correct your tank is using 2dKH per day. And here I try to keep mine from changing by more than 0.2dKH during a day!I use the seachem alk and calcium which is a powder, and my tank is up to almost 2 tablespoons a day now. I use the redsea magnesium and have the lfs shop (but only the person I trust now) to do it, and I start super low with that. So when I found I was 100 ppm down plus maybe 150 I dosed with 20ml then 30 then 40 then 50. After 50 I tested and was right at 1390-1400 range. It took a week and I literally ignored and threw their instructions away. They are terrible and extremely confusing and I am honestly surprised people haven’t crashed their tanks by using those specific directions.
Have you ever considered a calcium reactor?
