Hi everyone! It's me again, back with some questions about under gravel filters.
I'm wanting to set up a nice big fish bowl (10" tall/6" deep = 2 gallons?). I believe what I have for it is an under gravel filter, at least that's what someone said when I posted it before.
My questions are:
- How do I use it? Is it gravel, filter, gravel? Do I mix charcoal, sponge filter stuff, biomedia or anything else for the under part?
- Live plants. When I use the google, about two thirds say don't and one third say go for it. I /really/ want live plants, as this will likely hold snails and a betta.
-- Along with the live plants, what about using dirt as a substrate? I assume it's a silly thing to ask, but you can't know unless you do lol. What about under gravel stuff, under gravel filter, thin layer of gravel, thin layer of sponge filter stuff, gravel, dirt, gravel? My gravel is on the smaller side, so I'm not worried about thick layers.
Thanks! This will hopefully be a far easier setup than the little metal tank haha
