Hello Seachem,
When computing for the dosage of fertilizer we need to add into our aquarium, do we simply use the volume of tank, or should the volume occupied by the hardscape + substrate and/or the volume of water that goes to the canister filter/sump be subtracted and added respectively?
I have a pretty deep substrate which in my estimate is between 10 and 20% of the total tank volume.
