My tank's 5x2x2, holding 450 litres after displacement from gravel/wood/rocks etc. Because of a bad back I use four smaller filters (two Eheim 2028's and two 2217's) instead of bigger filters like the 2080 or 2260; I'd never be able to move them.
That gives me 4000lph rated flow/2800lph real flow, plus another 3000lph from two Koralia 1's I'll be adding shortly. But I'm unsure what would be the best flow pattern with six water outlets. I previously used a spray bar across the back of the tank, but I ended up with BGA along the front sand where tall wood blocked the forward flow and created dead spots. That was without the Koralia's, though, so maybe those will help alleviate the problem if positioned correctly.
The two choices I came up with were these:
On the right is the current setup, with all six outlets positioned so the water flows back to front, down the front glass, and back again. On the left is the option I'm leaning towards now, with two spraybars and a Koralia at each end of the tank; at one end the outlets will point down towards the front, at the other up towards the back.
Do you think that would work? Any suggestions are appreciated.
