Could use some advice please


I am a long time saltwater guy moving over to freshwater planted and am a bit confused on the lighting. I have been using T5 HO and Metal Halide so long I am unfamiliar with today's lighting options for freshwater.

I am setting up a 20 long, which is 30" long and 12" deep. I plan to use a versa-top glass canopy. I am only interested in some lower-mid light, easy to maintain plants. I do not want to have to use any CO2. I plan to use Eco-complete substrate. Ive read that some plants like Anubias, java fern, and maybe couple swords would be a pretty easy to maintain tank. It sounds like just the Eco-complete and Seachem Flourish Tabs would be sufficient for those?

So I would like a light that would allow me to keep some plants, but not require CO2 or ferts.

The light needs to be able to sit on the aquarium, I can't suspend it. Is it best to just put something like this on the tank-

Or would I need 2 of those? Is there a better option than those lights?

Thanks for any help

For planted tank lighting, T8 fixtures were made obsolete by T5's. For a low light tank, check out various T5NO options.

Two of those T8 fixtures would work, but not very well. If I remember right, a lot of the little light they emit is lost due to subpar reflectors.

Obviously you will pay a bit more for better fixtures with better reflectors, but you will be happier long term.

ok, i'm having trouble finding a t5 no fixture. all of the normal vendors i use for my saltwater supplies have T5HO, which i know would be too much light. do you have a recommendation or link to a good 30" T5NO fixture?

I realize it is only 24", but the 30" model gets horrible reviews.

I'm worried about having too much light since the tank is only 12" deep. I want to keep this as simple and low maintenance as possible since i have 2 very young kids and not a ton of extra time on my hands. Going with 2 T8 bulbs @ 17W a piece would not be a good option?

For a low light tank it should work fine.

A T8 light should give you good low light, around 30 micromols, if you have 2 inches of substrate. You don't need two bulbs which might be too much light without CO2. Picking a bulb is largely a matter of what looks best to you. I would go for one of the 6500K bulbs, but I have no idea how they differ.
