Grim, been reading this thread for weeks and it has helped but I'm still a little confused. I just ordered Aquactinics TX5 HO 36" fixture with
1 Aqua sun
1 Super Actinic
1 Pure Actinic
2 Aqua Blue +
I'm wondering about bulb placement since sites 1,3,5 are on one switch and 2,4 are on the other. Right now planning to have 2 and 4 come on first and go off last. Your suggestions appreciated. Hope I haven't messed up. Also have retro T5 with 2 bulbs that I'm currently using to supplement PC that I might still be able to fit on the tank with the new fixture. Would 7 39w T5's be too much on this 65? It's 24"deep. I now have mostly softies and 1 crocea clam.
