Alright, last post regarding my 40B, I swear! I'm planning on setting up a fairly low tech 40 breeder, hopefully a finnex planted+ light, good filtration, dosing with excel and maybe trying to get into dosing other nutrients?, as well as possibly some form of planted tank substrate. I'm coming from a 60 gallon planted tank that I don't dose, and that only has pool filter sand (I use root tabs), but in reality even with the finnex planted+ on there, no amount of light coming through 2 feet of water seems to be enough for these finicky carpeting plants. So, now that I'm only working with 17 inches of depth, really about 15 after substrate, what can I do? Is dwarf hair grass an option? Dwarf baby tears? I think dwarf sag might be a bit tall as a carpet for a 40B, but what about crypt parva?
