Aquarium Advice Regular
I was considering starting a 10 gallon aquarium to accompany my 20 gallon, and I was wondering that if I wanted to cycle the tank faster could I take a filter cartridge already in use on my 20 and use it to cycle my 10 faster. And if I did pwc on my 20 and put a few gallons of the removed water into the ten gallon would this speed things up? (for all those who lack patience)
