Hi there,
my first post - thanks to Jim at The Green Machine for pointing out this site to me!
I recently cleaned up my 325l tank and planted it up with some great plants from TGM. I now have a question about filtration, or more precisely water movement. I am using a Back to Nature modeled background which has probably some 25l of space behind it. I divided this space into three chambers, using thick foam pads, of which the middle one is filled with filter foam cubes. I am pulling in the water through a hole on the left hand side with an Eheim 2322 thermo filter (500l/h), through which it is filtered mechanically, before pumping it into the second chamber of the background, which contains the foam cubes. The water runs through the main foam cube filter before being soaked up again by another E2322 (I use some more biological filter material in this filter) in the chamber on the right hand side, before being pumped out through a hole at the top of the background. There is another outlet at the bottom of the background for possible excess water to flow through.
I am very confident that the filtration is working - to my understanding the slower the pass through rate, the better the filter will work. I am getting concerened though about water movement, after reading a few posts on the forum. I do think it moves reasonably much, but I read about desired flow rates up to 10x the tank content, in order to effectively spread CO2 and nutrients...
What do you think, thanks in advance for your help.
