when I add frags, I readjust mine slowly using window screen on top of egg crate. I just remove a layer every couple days over the course of 1 or 2 weeks. That way it doesn't have to succumb to variances in water flow, if I were to start at the bottom and slowly move it to the top.

I've noticed some of the colour coming back to my open brain frag finally. It browned out when I got it about 2 months ago, and today I noticed it's red coming back. I think the major changes I did was change 30% of my bulbs to actinic (had zero actinics before hand).

I also changed the photoperiod from 13 hours for 4 bulbs, and 12 hours for the other 4, to 12 hours on the actinics and 8 hours on the 10k's. Some colour's returning now to some of the browned out frags from a while ago.

What do you guys think about Tek - 36" HO T5's?
It is 39 Watt not 50W so would you get nice SPS colors from 36" inch long 39Watt unit or woud you go with 250 watt DE MH instead, for 36" long tank?
thx.

I used to run a 4x39W Teklight over a 46 bowfront. I only had LPS/softies so it wasn't a big deal to keep those guys growing. I'd go for the 6x39W 3-foot unit for SPS.

How deep is the tank? I run a 4 bulb 36" Teklight on my 36" tank. Love it. Stays cool and is amazingly bright. Some of my softies love it, some of them not so much. My 1 Monti Cap seems to like it as well.

My tank is 24" deep, thinking about 2 HQI DE pendants or 6x39Watt HO TEK t5's.
