I figured I would run two reverse power heads (maybe 170-200gph) to two UGF plates. I've seen a lot of people have success even with plants in other forums. This will also lift the debris.
The main reason the planted tank folks hate this is because it deprives the plants of mulm and you have to have a very good mechanical filtration system. I'll be running it with two AC110s for mechanical filtration. Also, it's supposedly bad because the roots will get disrupted but several people that did it, said it wasn't a problem because the flow rate was so low.
Why it works for planted tanks -> easy to dose ferts to roots, CO2 diffuse from bottom directly to the roots.
I think the reason everyone else hates it is because UGF has gotten such a bad rap over the last few years. They're hard to remove. If you have fish that dig, it can create uneven water flow. Debris can get caught under rocks and decorations.
I'm spending way too much money right now on fish, but it's something I'm considering. Like the others, I prefer plantd tanks for display and I think they look nice. Although having done it, it is a pain to keep clean.
The other option might be to increase water flow at the bottom of the tank to lift mulm up to the filters.
