I added the Powerglo back to my tank and the red is better on my rainbows.
Power glo bulbs by themselves are a little dim, I think you'll be happiest with the fuller spectrum from combining them
Do you think ill have a problem that the bulb is 8 more ws than recommended?
i know that i put a 24 watt bulb t5 in a fixture that was for a 18 watt bulbs and it burnt out the ballast in about 30 mins
