I thought my tank was really blue with just the t-5's on. I also need to figure out what brand and I don't have a ton of money right now so I really want to find something that will be nice.
2x 14K phoenix DE, on dual BlueWave ballast, with no supplement.
I will never change bulbs. Finally found the color I wanted. I probably could get a little more growth with another combo but it's a minor issue compared to a simple dual ballast set up and nothing else.
