Would adding another filter start a bacteria bloom?

I just recently added an AC300 to my tank to assist my XP3 for my 75g tank. I have 1x 8"Oscar, 1x 7"Pleco, 1x 7"Channel Cat. The bio-media inserts for the AC300 are brand new. I noticed the water was a little cloudy, and is still cloudy after the water change. Parameters are the same now as they were before.

Ammonia 0ppm Nitrite 0ppm Nitrate 15ppm (before a 25-30% weekly change)

could it be dust from the bio media ???

nah, I rinsed them in a bucket of aquarium water. Im not overfeeding either. Its bizarre

Unless you rinsed the bio max under running water for a couple minutes, that is likely the cause of the cloudyness. Give it a couple more hours to clear.

Ok thanks for the help. Probably might be what happened, I put the filter on a week ago, but when I water changed I did vaccume the gravel which might have stirred up some sediment and the HOB drained so it be some dust when it restarted. Ill check it in the morning.

adding an additional filter will never cause a problem in an existing, filtered tank.

taking away a filter can, however. all of a sudden your fish waste does not have enough bacteria to break it down and you can end up with a ammonia/nitrite spike.

Still a bit cloudy, and a slight odor to it. I am going to clean my XP3, its been a little a while. Im guessing thats the problem, parameters are still good.

just cleaned it, the polishing pad and the carbon were disgusting and smelled like ****. Should I water change 2 night?

Having a spike after adding bio media, is 100% normal....Whether it is adding to an existing filter, or add a new filter all together, expect a spike. Happens in my tanks anyhow.

Thank you, thats the answer I was looking for!
