I have a 47.5 tank (37L X 18W X 21.5H) with two linear strip T5 bulbs of 39W each--the hood is sitting right on top of the tank. There's about 4 inches of substrate.

I saw a chart here that indicated whether I had low-medium-high light and I can't find it after doing a search.

My tank is on it's way to be being heavily planted and I'm trying to figure out if I need more light. My set up came with 1 39w and a 78w bulb. I was told to swap out the 78w or risk getting algae so that's what I did. Now, I'm not so sure.

Here are the plants and their number:

Cryptocoryne crispatula var. Balansae 10
Aponogeton madagascariensis 1
Microrium pteropus var. Windelov 1
Crium natans 1
Criunum calamistratum 1
Vesicularia dubyana 2
Numphaea zenkeri 3 (bulbs, not sprouted)
Cryptocoryne parva 3
Eleocharis acicularis 3
Anubias gigantea 1
