This brings up another subject. I've heard the purple coraline doesn't like too much light, but the red and pink does. However ever tank I've ever seen is covered in purple coraline and has as much light being generated as a Las vegas casino. I will have (2) 250W MH 10k and (2) 96W Actinic 03 CF, will this be sufficient, hope so since I've already purchased them.
