Currently using a 6' Aqualight Pro 150w version with 13000k Geisemann bulbs which are good for punching through the 29" depth of the 220g reef tank. I am in the process of switching over to a 250w version with 14000k AquaConnect bulbs so I can bring home more of my sps corals that are currently in Chin's & Marie's tanks
Been very happy with the results produced with the Geisemanns even on this deep tank, because I'm softies/lps heavy.
Hopefully the upgrade won't blow my breakers. Wanting to go 250w DE because I can then add glass tops over the tank without worrying about light loss, which was a real concern with just 150w over 29". Hopefully everything will work out this week & I'll be able to reduce my evaporation rate & room humidity.
On my frag tank, I have a dual 65w PC unit with 9375w GE bulbs that have been very good for colour & growth.
