p205 can I add to aquarium
I was given a box of dry P2O5. It is sold as Super Phosphate. NPK ratio is 0-45-0. Can I dilute this with water and add to my tank? Could this be used in place of KH2PO4? This is found in Seachem Florish in a small amount.
If I can use it does anyone have an idea of ratio to add with water and what to dose in tank?
