If using soil, does the current in the tank have to be at a minimal otherwise the water will be cloudy. Will the soil dirty and clog up the filters more rapidly? This mehtod sounds a little high maintainance or am I missing something here. Gravel seems to be the easier setup with less maintaninance on the filters. Sure there is that great benifit of the soil providing nutrients, but that can be achieved from supplements as well. With gravel, you don't even hesitate when it come to rearrange plants or reaquascaping. I am leaning more toward Florite right now.
