Whatever you call them — gravel bogs, veggie filters, regeneration zones — we are all talking about planted gravel sediment traps. They're extremely effective at removing solids by both interception and sedimentation, and they can be scaled up to clear bodies of water of any size. It's all about the physics.

It is tough to maintain good CO2 levels that way, but if you supplement with some excel, it should provide some added carbon for your plants that would otherwise outgas by nature of the filter.

Sorry but under gravel filter have a lot of negative problems with the worst being cleaning them. The only real way to clean them is to take the whole tank down. They are also hard to tell when there dirty and as they do get dirty your power head will slow down and less water is pull thru the gravel. Just go with a sponge filter with an air lift.

A plastic liner waterproofs the basins and avoids soil contamination. The depth of filter beds, which are planted with aquatic plants, is normally 60 - 80 centimetre (cm). The bottom slope should be 0.5 - 1.0% from inlet to outlet to achieve good drainage (MOREL and DIENER 2006) and the filter length no longer than 25 - 30 metres.
