Hi, I've just started getting into planting my tanks, and i was wondering if it's okay to just use flourish? I'm a little weary of excel because i have some little shrimps and i don't want them to get poisoned or something. Also, the root tabs are a little spendy for me. If i absolutely have to, I'll use them but I'd rather just use flourish if i can. Right now i have a ludwigia repens floating (I've heard it can be a floating plant) and some sort of crypt, i dont remember exactly what kind. Any help would be appreciated!
