I have two F15T8 / max plant growth zoo med flora sun's 18", on a marineland 46 gal bow front. I have been guessing it is low to med so I am looking for plants according to that.
Thanks for the help.
Your T8s are 15 watts per bulb. So, you have 30 watts of light, that's very low. You can still grow Anubias, Java fern, and some varieties of Amazon sword. But, you'll have to limit the plants to those that require low light or shade.
You can also float stem plants like Anacharis (Waterweed), and Pennywort. Both will grow well close to the light source.
