Hello all! I've nearly finished cycling my 10 gallon fish tank! Woot woot! :;banaman I'm filling it up halfway (so 5 gallons), and it has a quality heater as well as a light filter that I'll put pantyhose over if need be. I took off two 15 watt full spectrum daylights from my 55 gallon tank, and can use either one or two (they fit almost perfectly!) So I need recommendations for 1) A ground cover plant 2) Substrate (preferably cheap, but it's only for a 10 gallon, so if it's a bit pricey, it's ok) 3) If I will need CO2 injection (and if it's safe for the betta or not) 4) Any other tips Thanks so much!
