Hi all.
So I need some help here. I have a 40B tank and I also have a Tek 6 bulb T5 light. I have it on my tank with the brackets in the highest position possible which puts my lights about 12-14 inches off the water. I have some SPS coral in the top of half or so of my tank. I have a monte cap which is practically dead. Its glued to a rock that I cannot remove. It sloughed something aweful. I've all but written it off. I have a monte tree that is about at the same height and lost some color as well, but seems to be doing ok with a piece of eggcrate above it. I some sort of green sps that I picked up off the $10 rack at my lfs that seems to have colored up nice, but has also started bleaching around the edges. My frogspawn which is on the bottom doesn't fully extend anymore (but other than it won't go fully extended like it did with my last light, a cheapo 4 bulb Oddysea, it seems to have good color and does extend about half way). The eggcrate also covers the frogspawn. Under the Oddysea light, it was growing well, doesn't grow much. I have a handful of zoas that seem to be doing well. I have a yellow and green Acan that seems to love the light about mid way up the tank.
Anyway, I say all that because I think I have too much light. I currently run ATI bulbs. 1 Aquablue special, 1 Purple+ and 4 blue+. If I were to replace the purple+ and a blue+ with True Actinic, would that take some of the pressure off my corals? Current schedule: 2 blue+ from 12:00 to 10:00. Full strength: 3:00 to 7:00.
The bulbs are about 7-8 months old, so I'm thinking they need to be replaced (that and I had a massive algae bloom recently). If the acentics would ease up for my coral, I'd like to do that. Or maybe I should just run the 2 blue+ for a while? I'm kind of at a loss.
Water params are good. No Nitrate/ite/ammonia. DHK 8.5 (a bit low). Ca 460. 0.25 phos, but I'd bet that is from my top off. I have new di resin coming in the mail. Been almost 9 months since I replaced that :-(. I don't know Mg, got one of those test kits coming as well.
