Hi Fishlore fam. Help, help, help. I took out my filter sponge that had been in the aquarium for like 3 months and rinsed it completely. It’s a single filter sponge. Lots of debris came out of it when I rinsed it by squeezing tightly in another bowl of water containing the same water in the aquarium. I put the sponge back and ran the filter and it worked as usual. The next thing I noticed after some couple of hours is a milky cloud (I guess bacteria bloom) in the aquarium. I got confused and scared and watched my fish (paradise and guppies) with close attention. After some hours the milky cloud cleared and the aquarium went back to normal clear water. WHAT JUST HAPPENED?
