great thread
I'm just getting started with corals, after 7-8 years of FOWLR.
I have two types of zoas and I'm (hopefully) getting another 7-8 types from an order next week, so I'm looking to get peak conditions for these guys.
I think i've unconsciously decided to have a zoa/paly-dominated tank. the variety is amazing.
Anyway, what amount of light is considered sufficient? I just tend to put everything at the top of my tank, and I currently have Armor of Gods (doing great) and some RPE's (not budding, very long stalks, poor red color), so i have a mixed bag of success.
I just replaced my 175w HQI's last night. I had 20k's, replaced them with 15k's.
In additon to the two 175 metal halides, I have two 92w PC acitinics. All of this light is part of a hood.
I think this is enough light, (is it?) but does anyone think that it's enough light for some zoa's to like mid-tank-level?
And will the 15k temp of the new bulbs be an improvement over the 20k bulbs, which have been in service for a year?
Great thread.
