I have been struggling with this for a little bit now, searching high and low, and finding every argument for surface agitation, for no surface agitation, and everything in between.
I have a 36G Community Tank, with corydoras, guppies, zebra danios, a pleco, frogs and snails, and will have marbled hatchet, neon tetras.
My filter is a canister filter, Penn Plax Cascade 700. I also have a small Hydor Koralia 240 circulation pump.
I'm trying to set up my canister filter to play nice with my floating Amazon Frogbit. I have tried the outlet nozzle, but that blew the floating plants all around, shoved them to a corner. I tried isolating them with airline tubing, but that didn't work.
I've tried with a spray bar, but that too seems to be blowing them around.
I have pressurized CO2, high light/tech, medium-high planted (will have all plants tomorrow). I love the frogbit, and want to avoid getting a new filter or an air pump, if I can. There must be some configuration I can setup to accommodate floating plants with a canister filter?
I've thought of no surface agitation, only having floating plants on half the tank (is this better than the whole thing?) by using fish line, point the spray bars straight down while still having them 1" under water...
What am I missing here?
I've attached a YouTube video link here
of my tank with a handful of Amazon Frogbit, most of the other plants are fake (real coming tomorrow).
