Four months ago I switched over to T5 from PC lighting. Since then my zoanthids and pallys have decreased in overall diameter by at least half, have basically no stalk to them and their skirts have become very thin and stringing. (Has anyone ever heard of this)?
My tank has a 36†Tek Light fixture and giesemann bulbs. Bulb configuration is Pure actinic, actinic+, aquablue, then actinic+ from front to back. My tank is 36†long and about 17ish inches tall, Skimmer and hang-on filter. The fixture is about 10-12†for the top of the tank and basic water parameter are testing where they need to be.
They are growing and spreading rapidly but there is definitely something going on. My other corals seem not affected; this particular tank has clams, sps, lps, shrooms, softies, anemones and all are looking great. I am at a bit of a loss; I have not changed anything other than lighting. Do I have too much light, wrong configuration, lamps to close to tank, or is there something else( not lighting) that I am not aware of.
I have already posted this once so forgive me but, I know there are a lot of aquarist out there with more experience with zoa's than me. Any advice would be helpful.
