Filtration and Heavily Planted Tanks

Hey guys/gals - I need some background info here.

I have a 75G heavily planted tank. Sicne I have been adding CO2 and ferts my growth has been explosive.

Some have suggested that I do not have enough filtration on my tank given the size and how heavily planted it is. I have single Eheim 2215 canister and a Vortex XL Diatom that I use about once a week for 3 hours.

So here is my question - How do I know if I have "enough" filtration?

My 3N levels are all where I want them to be, and I water change once a week.

So....what am I looking for here to let me know if I need more filtration?

Thanks!

the more heavily planted it is, the less filtration you need.

plants do almost all of the biological filtration in a tank, and a filter is really only for mechanical filtration, and as a powerhead.

You have enough filtration on the tank.

I agree w/ Thanks.

Filtration isn't a big factor for planted tanks. But you might have issues with water circulation.

Yeah, water circualtion can be an issue with a heavily planted tank. All those plants block the water flow, but if you use a spray bar and position the inlet on one side of the tank and the outlet on the other you should be ok. How are the fish and plants looking? If they are doing well then don't mess with it.

Exactly. There should be a distinction between filtration and water turnover (...mmm, turnovers...) which is directly related to circulation or water movement in other words. I thiink most of our filters accomplish this goal, but in larger tanks, this may be more of an issue. I, for instance, use a powerhead in my 90 gallon to provide additional circulation. I've noticed my plants grow better if they have good circulation, and areas with less circulation tend to accumulate algae faster. The plants gently swaying in the flow also provide movement which adds to the aquascape, I think.
