I considered the seeded sponge my good bacteria. I spent $28.00 and got the whole sponge filter. I had a pump, air stone and tubing, so I just hooked it up and plopped it into the tank. Some of your bacteria will be dead, so you still have to do huge wc for 5 days while the good bacteria catches up with the bioload (poop) from your discus. They can really poop!
Have you cut up a sponge like that Daniel? I’m just wondering if he should cut it up in the bag it arrives in rather than out of water? Good way to spend the time while the bags acclimate to the tank temp, right?
