Think hairgrass will grow OK without C02? I'm fine with it growing slowly, I just want it to be healthy.
I'm not stuck on having the grass, I might be tempted to go with the easiest green carpet I can make work low tech.
It will be fine. Some put it in a Unfilter unheated really low tech bowl. That is what I am going to do with DHG. Newman has some in his bowl currently.
Just my animals:
0.2 Cornsnakes, 0.2 Bearded Dragons, 1.0 Water Dragon, 0.2.1 Crested Geckos, 1.0 Tiger Salamander, 2.0 Anoles, 0.0.2 Red Eared Slider Turtles, 0.0.1 Map Turtle, 0.0.1 Hermit Crabs, 1.0 Hamster, 1.0 Rabbit, 0.1 Horses, 2.2 Dogs, 0.2 Cats, Chickens, Ducks, Oscar Tank, Planted Bowl, 2x 10 Gallon, 2x 0.5 Gallon, 5 Gallon, and Planted 25 Gallon Tank....Is that it?
