Help with ATI/Kessil setup

[coralor]

I do like the T5's in the middle idea better. Especially too because one 48" ATI 8x bulb is much cheaper than two 4 bulb fixtures. Thank you!
Hoping a 48" ATI will be sufficiently long enough for a 54" L tank with a narrow overflow on the 34" wall end. From what I've read that should be plenty. Opinions anyone?
To make the tank any longer (ie and use a 60" ATI) makes the tank kind of long for where it will be sitting.
And for help with the over flow, returns and power head positioning should I be starting another thread? I have some ideas and questions based on my own experiences I would appreciate bouncing off someone. Please😊
