I run a 48 inch T5 6 bulb with two 36" reefbrite Luni Lite actinics. Works great.
I’d suggest running 4 blue plus, a coral plus and a purple plus. For the reefbrites it all comes down to how much you want to spend. 2 are better than one and one is better than none. Reefbrite xho’s are the best option but are quite expensive. I use the reefbrite techs and they work well, little cheaper than the xho’s. Be sure to get all blue reefbrites, no need for any whites
So would 6 bulb t5 be enough for mixed reef with some sps near the top ? Basically should I add a good reefbrite for more par? Or just get one for the shimmer and blue pop ?
What bulbs do you have in them ? And where did you buy your reefbrites ?
