Victoria SPS Dominated Reef Owners

Maybe because of a combination of lighting spectrum(color) and par? You have a lot of bulbs that peak at or near 450nm. That produces a lot of blue color. You are lacking some other colors. You can try to get some other color bulbs and play with the combination to see if your corals have better color.
Also these blue bulbs don't have as much par as some other bulbs that peak at lower spectrum. I don't have links that show the par of T5 bulbs since I am only interested in metal halide bulbs. But you should be able to find out the information by googling it.

Christy,

I'm not actually running Zeo - just using a few additives and now using NP Biopellets.


George,

The Blue+ lamps actually have pretty close to the same PAR as lamps that would be rated some where around 10,000K to 12,000K.

See this site for more info about T5 PAR values: http://home.comcast.net/~stevelarsen00/site/?/home/

actually his bulb choice is great, personally i am not a fan of middays and would run a aquablue + (or something similar instead).

As per K i barely post it due to the same reasons as you guys. i do a cap once or twice a month of TA K. Funny thing about water changes, i find that i get better results with only doing a 10% water change once every 2 weeks. You could also look into dosing b-balance for trace minerals. I haven't started dosing it yet but plan on it in the new tank once i have moved.
