I just bought new filters for my goldfish and Betta tank, penguin minis. The old filters I had were horrible which was the reason for the change. I put the new filters in 3 weeks ago and left the old ones in at the same time. I took the old ones out yesterday and the tanks got really cloudy which means I may have a mini-cycle on my hands. I added stress zyme and ammo-lock (which detoxifies ammonia). Is there anything else I can really do? How long will this most likely last?
