okay will do ben, 54w t5 controllers wont fit in my length tank so i have to go with another set of 39w t5s. With the pair i got already that brings me up to 160w bearing in mind its only around a foot wide the tank and the lights will be on top of each other a bit will this be okay for the moment? I may be able to push a twin set of PC's worth it?
BTW i getting these new lights coz of a bet my dad lost over my sociology gcse mock result, i proved him wrong and got a high A!
