Re: [APD] Dosing CaSo4

CaSO4 is 29% Ca, so for every 20 ppm of Ca added, you're adding 48 ppm 
of SO4. 20 ppm Ca is a decent level and will give about 2.8 dH Ca. The 
SO4 levels in my tanks get much higher (150-200 ppm, maybe higher) from 
the MgSO4 and K2SO4 I use. Never have had any issues with it.
