I hated the fact that my returns and drains came from the same spot so I re did there turns and brought them up over the back, also got more flow out of my water blaster pump.
I know I'm pretty new here but I just did the same thing with my evo LEDs. I was running two 20 k 120 w evos and just added one t5 ati purple plus. I love the color and am debating on adding another t5 bulb, either a blue plus or a coral plus.
