If it holds that much I'd say it's fine. You just have to do water changes often since it wont have a filter.BOD said:it holds about 2.3 gallons...
I think that's more than 3 gallons...not sure though so if someone else knows better please correct me. It would be easier to find heaters for a bigger tank but you can find small ones if you look. If I'm not mistaken someone has posted a thread that listed some small heaters.BOD said:i was thinking 50% twice a week...what about this one its 15 litres..... is that more or less...i dont know how u work it out![]()
