Under gravel jet challenge?

AFigure 700 GPH is good current without disturbing the plants.

700 gph for 6' tank is nothing, even you use 1 for each side. You don't want to disturb your plants but your tank still need a right flow to keep it healthy. I would say 900~1050 gph to have a gentle flow in your tank...Remember your plants still need a right flow to feel happy, healthy too.

Yuki Rihwa so for a current good enough to keep debris floating for the HOBs more like 700+ per side?

*It's a no for 700~900 gph
*Might be with 1050 gph with correct position and depend on your plans stock, if not it might create too much current for plants.
*Also, depend on how heavy you're going with plants. It doesn't matter if you keep a bunch of fishes and have a few anubias...Some folks still call that "planted tank"
Notes:
You're using gravel so once the waste set on them it's impossible for Ac110 to pick it up, you will need a major water flow to do that and it won't work for planted tank.

I've got a bunch of grass and anub and a handful of other big leaf plants. Nothing too delicate because they've already been taken out by some of the Inhabitants. Yuki Rihwa
