I have medium light on my 40 B with a 24/7 on top. I'm seeming to have good growth on the plants I have but curious as to what other plants you suggest. I'm on vacation now and can think of all the names of my plants but some include hygro low grow, apono ulvaceus, rotala rotundifolia, rotala mini type V, chain sword, and some others I can't remember. I dose excel daily and micros and macros on opposite days. Thanks!
