I purchased a 90 gallon tank and it came with a somewhat new Coralife T5 48inch fixture. https://www.amazon.com/Coralife-Aqualight-Output-Fixture-48-Inch/dp/B0030YFEP4 The fixture seems pretty good. It has 2 bulbs. One is a 10,000k bulb and the other is a blue bulb. During testing, it seemed a little too blue for my tastes so I put it on my 55 gallon and didn't like it at all. My blood parrot looked purple. I'm thinking that removing the blue bulb and putting one of these https://www.amazon.com/dp/B01CJFQYOO/ref=twister_B071DRQ6BB?_encoding=UTF8&th=1 on instead will solve my problem. Perhaps another 10,000k bulb? The box the fixture comes in says you can do any combination of bulbs so feel free to experiment. It details the props of each bulb as does the Amazon listing does. Before buying anything, I'd like to see what it all looks like on the 90 gallon when it is all set up. Does anyone have any experience with this fixture? Like I already said, I'm pretty sure this issue can be easily solved with a different bulb. Any thoughts or ideas?
