That depends what her filter is. Is it one which contains a single sponge? Or does it have multiple sponges and/or ceramic media? It should be fine if you take up to 1/3 of her sponges.Right i managed to find a spare sponge for a filter so would i be ok to swap a whole new filter for one of her used ones? Or will that affect her tank??
This is the "bacteria in a bottle" type of products which I was talking about earlier. I have not seen any proof that they do anything, but if you happen to have some, I don't see any harm in putting it into the tank, then continuing with a fish-less cycle using ammonia.I also came across some Filter Start, is this any good to start the bacteria off? Or is ammonia the best thing to use?
