What is this and how to stop it?

Yes, MgSO4 and CaSO4 is for gH.... target around 30ppm Ca and 10-15ppm Mg into your water change water.

Then target 0.5 degrees of kH using KHCO3. 0.5 degrees is enough to kepe pH stable without overly contributing to Potassium levels. Now, if using that, you likely can get away without any K2SO4 dosing... Because KNO3, KH2PO4 and KHCO3 will provide more than enough K.

Get a journal started up, I'll certainly follow along. It's good to keep track of things.

Will do.
Ill get this items ordered today and start figuring out correct calculations. I think i will just finish dosing with Thrive+ (just to fonish the bottle) and then mix these and start that route. I really hope this helps heal my Ca and Mg problem i have going.
