Just did a water change and...

I just did a water change and I cleaned out my Canister by washing all the baskets out. I went to hook it back up, I primed it and everything, waited 2 minutes, and when I plugged it back in all kinds of white stuff came out of the spray bar like white flaky stuff.
Is this just stuff that was built up in my outlet hose and spray bar?

My filter is also being very noisy. I have taken it back apart several times and made sure the impeller is in securly. Now it's almost a sound like the filter isn't full. In the actual canister itself I hear a lot of swishing of water going on. And up by the spray bar it sounds like there is air coming out.

Sometimes this happens to me too, it will all get sucked back in the filter. No need to worry

Yup, every time I do it I have junk get shot out into my tank but it will get sucked back up.

I always do the filter first, for the same reason, all the crap coming out of the filter when I turn it back on. Not to worry, just do the filter first, then the water change.
