Hi Danger69,

If you have a 25 gallon tank, with substate, my guess is you have less than 25 gallons of water. For Estimative Index dosing for a 20 gallon you would dose the following:

KNO3 = 1/4 tsp 3X week
KH2PO4 = 1/16th tsp 3X week
Trace Elements like CSM+B = 1/16th tsp 3X week
50% weekly water change

I dose my nutrients dry, just use a measuring spoon. I had to go to Bed, Bath, and Beyond for set of small measuring spoons for 1/8th, 1/16th, 1/32nd tsp sizes.
