yeah , the thing is i have a timer on my lights but i dont have dual compacts , it only holds one bulb so i have to change the bulbs after the 2 hours , its a pain in the ass but its what i have to do till i get the money to just buy dual PC,s i was thinking about going to home depot and getting a PC, fixture for 30 bucks then just make my own cover , but to get back on subject yes i do mean for coraline and algea and what not ,
The specs are 50/50 Combo of 6500k Trichromatic day light phosfphor and actinic 420 phosphor in the same lamp ??? Provides high intensity full spectrum illumination strong in the short wave length blue region essentail for photosynthises corals and inverts. thats all it really says ,. And about the actinic lights being on for 4 hours should it be more or less or it that fine ??
