Well I am getting a lot of good coraline growth so far but today it looks like I'm getting some dinoflagalates again, ughh. I think honestly something is wrong with these bulbs, they are coralife ones that came with the nova extreme pro fixture so they are less than 6 months old, but do you think I got a bad batch of bulbs or something? Cause when I had many pieces of live rock in my temporary tanks for my fish I was powering them with 36" sunlight supply t5 fixture with no problems whatsoever with algae, with nitrates really high too, but no problems at all with any types of algae especially dinoflagalates. Also, when I started experiencing problems with them the first time it was right after I switched to the nova extreme pro fixture. So do you think it's worth a try to change the bulbs out?
