I'm gearing up for auto dosing. Previously I dosed KNO3,KH2PO4, and CSM+B as per EI recomendations, dry, but now I need to make up stock solutions (2) to feed my doser. I tried using Wet's (very usefull), APC's fertilator, Chuck Glad's, and Nutricalc. They all helped but I still had to do some paper and pencil work.
Now I'm no wizard with Excel but I can generate a formula when I need to so I thought I'd try my hand at a spreadsheet that would allow me to design any stock solution I wanted with the information I could gleen from the ap's listed above specific to any sized tank; all inclusive; no more work required.
