Ok, weird question time. So i just bought a tetra 1-3 gallon filter. Just so i could use the air pump and airline tubing that comes with it to make an air-stone. It was cheaper this way. Anyway, I now have a filter i am not using that is useless without the pump and lubing. I was wondering if i took out the filter cartridge and put it in one of my 1 gallon betta grow out tanks, just the carriage straight into the water, would it do anything? Grow beneficial bacteria? Help the tank in any way since i don't have a filter on it at all?
