when you do a water change of 50% or more and clean your filters at the same time you will get foggy water most of the time , thats what use to happen to me , the tank basically has to go through a cycle all over again, you kill most of the good bacteria when you do both at the same time. I have a 180 gallon tank and run 2 xp4 filters. when I clean the tank I only do 25% water change and clean one filter only, and a week later i will clean the other filter. when I clean my filter I take a bucket of tank water before the 25% water change and dump all my BIO MEDIA in. I have 4 extra baskets for my xp4's so I just put clean sponges, chemical media, fine filter floss, Then I take the bio rings right from the bucket of dirty tank water with all the crap on the rings that is all your good bacteria.
(And I let the filter fill with the tank water before the water change)-- and let the filter run for a few days= and then do a 25% water change. Then a week later I do the same for the other filter and no water change till a week later.( So I do a 25% water change about every two weeks!) never had a problem since.
If you only have one filter I would only clean the filter and not do a water change at the same time, I would wait a week or so then only do A 25% water change at most. Thats what works for me and never had water fogginess ever since. And if you do a complete cleaning I would save 1/2 of the water from the tank in a Rubbermaid clean out the tank and add the tank water back with de-chlorinated water and clean the filter a Week later. to try to preserve as much of the good bacteria as possible.
This is what works for me and hope it might help you.
