Heyya folks. That 96 watt quad light I bought (Coral Life) was only going to get me store credit, so I kept it. That's fine. It's only 20" long so I'll prop in up on some wood or something and put aluminum on the side so the whole tank gets the benefit. Anyways, all 4 bulbs are 50/50. I believe that it's two seperate bulbs, as I've never seen a 4 bulb set (though my eyes are virgin to the marine world), so if I can find an actinic I'll get it. My question is, are they necessary? And if so, can I use the current bulb for 9 months until it's no longer pushing the energy my mushrooms need? Thanks alot folks. If the AC picnic happens, I'll bring chips for everyone!
