Hey guys, I've had a setup since new year, I bought it already set up from a friend. Im wanting to change out the filter for a bigger/better one as the one in the tank isn't very good. I know all about the bacteria etc so I know I can't just swap filters but I was wondering if it would work running 2 filters (new and old) until the new one is seeded with bacteria?? Would this work and if so how long would I need to run the new one for and would it be ok for the fish?? Thanks
