vison 450

Hi guys, My first post but long time lurker. I bought a Juwel Vision 450 (100 gallon) tank with an Eheim Professional II external filter. The tank came with a dual T8 fixture AND a dual T5 filter. I have 2 x 36 watt T8s and 2 x 54 watt T5s This gives me 180 watts and a pretty low 1.8 watts...
