that is the link to the light fixture that i bought it says it is compatible with a t10 flora glo but i just dont see how it could fit if the fixture is 48 inches. it also says the fixture is ment for a 55 gallon tank but i figured it would be ok since they both said 48 inches
You can relax, it will fit. I don't know the technical stuff, but I have 48 inch tanks (a 70g and a 90g standard) and 48-inch fixtures and the 48-inch tubes fit exactly. ... You intrigued me, so I just went and measured one of my 48-inch tubes and from end to end (not including the pins) they are exactly 47 inches, so that's how it's done.
Your new fixture is the same one that I recently bought to replace my old one that after15 years gave out; btw, they cost $240 here. It is a very good fixture, i really like it. The reflector is excellent, and the electronic ballast works very well. It comes with two tubes that are garbage, but I took them out and used my preferred Life-Glo and such.
Did you get two Flora-Glo or just one? Can you exchange it/them? Reason I ask is that although I have never tried this particular tube, I am skeptical that it will be adequate, notwithstanding the blurb that it enhances plant growth. It is 2800K which in my view is too little (should be 5500K minimum, preferably 6500K). You may like it, but I suspect it will appear quite reddish/purplish, given the spectrum graph and low kelvin rating for this tube. You might like it mixed with a Life-Glo 6700K tube to balance. That's your choice, but I would suggest this tube on its own (or with another same) will not be the best. Petsmart will I'm sure exchange it as you haven't used it. We were talking about Life-Glo previously, and I still think that is the best for a planted aquarium and natural colours.
