Fertilizers in canister filters
Is there any point to putting fertilizer tablets (I'm thinking
specifically of Duplarit K) in one of the media chambers of a
canister filter for it to dissolve slowly? I do have some in the
substrate near the roots of the plants (but I came upon this too
late to put Duplarit G in initially).
Any other types of fertilizers that would lend themselves to this
method?
