Just a thought; Has anyone connected a pond pump to ......
flow either in a reverse flow......
(as the powerheads have a reverse flow)or in the regular flowing direction and connected it to the uptube on the undergravel?
I was wondering if i can do this in my 150 gal planted tank with a few occupants?
i have a canister filter in use too.
can i do this to achieve a turbo cleaning system?
or am i just a clueless blonde. (be gentle)
