Mixing excel with KNO3 and CSM+B for automated dosing
I'm looking to make a very low maintenance lowish light, no CO2 tank. I have one peristaltic pump I can use for dosing (got it from a friend for cheap).
I was wondering, can I mix excel with KNO3 and CSM+B (in a dark container to protect the excel)? I know I can mix KNO3 with CSM+B.. but I'm not sure about adding excel to the mix. If I can't.. I'll just have the pump dose excel.
I'm hoping to have PO4 supplied by the fish.. maybe dose it once per week or so.
