Thank you both very much. I have 2 70g AquaClear HOB's for my 55g. This is what I do: I clean the whole system, basket, filters, impellers etc., once a month. Every 15 days or so, I rinse out the filter media and anything else that needs clearing, tubes mainly. I place the sponge media at the bottom (have not changed that for years) just lightly rinse it, then on top I have a chemipure elite media and on top of that the ceramic media which I have not changed for years either (just lightly rinse).
By more efficient, I have been thinking of a canister system. My plants have been growing like crazy. There are even some in there that I don't remember planting! I keep having to prune them. Also lately I seem to be getting more algae than usual, which is somewhat frustrating. I have some snails, but they keep coming and going, not really a problem. Probably feed too much . . . The fishes live to eat
Glad for your comments.
