Are you talking filtration rate or water circulation rate? These can be two different things.Hi there,
I was wondering how many time should the tank volume turnover in a heavily planted tank turn over? and when calculating this do i include the sump volume as well as the tank volume?
I am a huge advocate of over filtration and keeping the current in the tank enough to make sure that no debris can settle on the substrate.
For instance, my 29 gallon planted RCS tank is being filtered by an Eheim 2215 which creates enough flow so as no debris can settle on the SMS I am using as substrate. The tank is very heavily planted and the shrimp seem to love it along with my Ottos.
You should try to balance the filter flow and the circulation rate. Too much circulation and not enough filtration rate can cause the debris to just constantly float around in your tank, so you will have to take into consideration the tank as well. What are the dimensions? Is it a tall tank, long tank, etc.
