Water Flow in Planted Tank
I recently received a very generous donation of plants for my 40g breeder planted tank. Originaly I had anachris naja, crypts, an anubias barteri and some vals. The only tall plants were the anubias and anachris but with the addition of all the new plants I have much more plant activity throughout all of the tank, from substrate to surface.
When I set up the 40g breeder I purchased a power head at random and ended up with a 'Sicce Voyager Nano' that is rated to 530 GPH and is FAR to powerful my tank. I currently have a HOB filter (actually hanging on one end of the tank) that is not producing sufficient flow on its own. In my photo the HOB filter is on the left side and the power head is in the back right. I am planning to switch to a canister filter (Fluval 306) at some point.
I am thinking of placing the power head under the HOB so the it 'helps' push the water exiting the HOB across the surface of the tank where in theory it should hit the far wall and go down, correct? Is this a good idea?
I was also thinking of putting sponge or some material to obstruct the flow of water in/out of the power head to reduce the intensity. When I turn it on my plants are being abused in current form (and location). Has anyone used sponge or a solid material for this?
The impeller seems like a soft material, I was thinking of cutting away some of it to reduce the amount of water it moves. Thoughts?
