How about this set up
Screen would be 9"x14" water will be coming straight from overflow running at a rate of 140gL/Hr
On both sides T5 will be connected straight onto the acrylic design over the entire length of the device.
2 x T5 38W 3700K
ATS will drain into a seperate chamber just in front of the return pump chamber seperated by an airtrap
oh and it will be connected to a 150gL DT tank
Any other info you might need to give some extra advise?
