I'm running the new variable seio's with controller a few maxijets and flow from sump for a turnover of 3400gph, about 40x. MRC calcium reactor, along with a controller for the lights, ph, reactor, temp, time etc..That much flow kinda suxs for zenia and cloves, kinda their standing upright, then they get blasted with some flow and then they get bent over. All the softies get transfered over to a 30g softie tank on Mon or Tue, so that will free up a good portion of the tank.

Just upgraded the righthand side light to a Aqualine AB 20k and it's awesome.
Left hand side is Pheonix 14k, I'm going to swap the 14k out for a either an XM or Ushio 10 this week. So L side is 10k, R side is 20k, grow out on one side and color up on the other. I may swap out the lights on the left side for SE bulbs and fixture, that way I can get a 6500k and go for ultra fast growth. I could really careless about the funky yellow color from the 6500k bulbs as the tank is in a remote part of the house and lights are usually on only while I'm at work
