The four I have now are 28 watts and are 4100k I wasn't sure if you could get different ones. Thank you so much for your help. I'll be getting the other bulbs tomorrow or Friday.

Mikaila is correct. I didn't know 4-foot T8 came in 28w, but doesn't matter. I certainly agree that you only want two tubes lighting. I have this (two 4-foot T8 tubes) over my 4-foot 70g, 4-foot 90g and 5-foot 115g, and it is more than sufficient for low and moderate light plants, which is the majority. Even with this I have to keep it to 8 hours or algae takes over. It's all about balance.

And the 6500K are the best plant tubes. With your situation, you can easily go with the less expensive hardware-store tubes. I use GE, Phillips, and have used Sylvania. T8, 48-inch, the "daylight" with 6500K. Just look for the 6500K as all three manufacturers make one tube with this K. They are all 32w, or were, but that doesn't matter as the length and Kelvin is what you look for.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
