I've got a 150 grow out for the silver aro I rescued a year ago and I'm waiting till it grows to about 24" before I transfer it to a intex pool pond. The issue is I've gotta siphon the gravel pretty often (which I don't mind) but sometimes I've got lots of school work and don't have time. I've got about 200 gal worth of filtration from the two canister filters but would an under gravel help with the build up of waste? I'm also getting some low growing plants like java moss and dwarf baby tears to grow over the gravel so would the filter be necessary? The left side is empty right now because I took out the Colosseum there because it had too much build up of waster underneath and I didn't like that.
