i have a 29gal and was recconmended that at least a 15k light should be used for coral tanks... i just replaced my 10k t12 coral life bulb with a 18k t8 power-glo bulb... its next to a actinic blue bulb... i can see that the power-glo is a little bluer when i turned it on and the coral life was brighter and less blue, is the power-glo weaker? or is that blue supposed to be there... whats your recconmendation
