Just cleared out over a dozen Italian Val plants as well as some shale. I gave it to my wife's elementary school. They're making a few small planted tanks for grade 2 classes. It is my plan to replant a crinum calamistratum where the Val was in my tank. I'm also adding another 2 bulb t5 fixture so in total I'll have 2 t5ho, 2t8 and 2t5 in my 4x2x2 dirt tank. I dose flourish excel daily. I have heard this plant requires high light should I be okay with this setup? How bout co2 requirements?
