I've read in earlier posts that the CSL 50/50 bulbs are not really actinic. Is this true? I just purchased some 50/50 10,00k/actinic 03 pc bulbs hoping that it would be the one thing missing from my coralline equation. I had a 10 gallon nano set up for about a year with 32 watt 50/50 csl pc and my water parameters tested perfect for what shoild stimulate coralline and I even added rocks with it on it and it never spread. If anything, it died off or was covered up by green algae. Now that I transfered everything into my 125 gallon, I have the same problem. I've had 325 watts of CSL pc lighting on the tank with no coralline growth whatsoever. My corals have always done great, but no coralline. Am I right in assuming that by adding the actinic 03 bulbs, I should have a much better chance of growing coralline than with the CSL pc's?
