I have a 55 gallon tank with 2 canister filters attached. The cannister filters take up about 6 gallons. In establishing an EI dosage routine, should my calculations include 55 gallons of water or 61? Seems if we are talking ppm, I should use the 61 gallons.

if you have substrate, wood, rocks, other decorations, etc, then you would be using less than both.

Do add in the canister filter gallons though as that water will dilute the dosings as well.
