You did not mention how big your tank is. But considering glosso, you should be able to grow it without a problem. Your only indicator is if your glosso grows longer stems than usual. That only means you do not have enough light. Good luck.

That is only a 10 inch high tank! Even a 2 bulb T5NO light, with typical very poor reflectors would give you high light. If you hang that light about 6 inches above the top of the tank you should still have good low medium light, and much better uniformity of light over the substrate. With good CO2 glosso should do fine.

All of the Coralife T5NO lights I have seen or seen pictures of had poor reflectors, so I suspect that one does too. At 17 inches it will give you only low light, but with good CO2 you should still be able to grow glosso. It might be harder to keep it from shooting towards the water surface and being leggy, so you will need to prune more often.

Can u explain to me the difference between a good and bad reflector? not the obvious stuff but other than having to be shinny whats does it have to have to be a good reflector?

With a good reflector you can look at the bulb(s) and see both the bulb and a reflection of the bulb or even two reflections of the bulb on either side of it. With very good polished aluminum reflectors it can be hard to tell how many bulbs are real and how many are just reflections. Each of those reflections is almost like having another bulb lighting the tank. With a poor reflector, the manufacturer hasn't left enough room on the sides of the bulbs for a reflection to be there, and/or the reflector is just a flat shiny metal part under the bulb, not one that directs light down to the tank.

All it takes is looking at the installed bulbs to see what kind of reflector you have. It helps if you have seen a good reflector before, like an AH Supply bright light reflector. Also, look at the photos of known very good T5HO lights, and try to count the real bulbs - it will be difficult to do that.

ok that makes sense thanks for the help. with this fixture if the glosso doesnt work out should i upgrade to a t5ho fixture? or do u think i can still grow a large enough variety of plants to be happy with what i have?
thanks again =)
