Hi I did a 50% water change today at noon.

Last water change was a week ago.

I did not do anything different. The only thing I did extra was I pulled off the top of the tubes from my UGF and inserted the hose for the water change all the way down there in an attempt to remove the junk from down there.

Then I feed the fish and left for a few hours. I just came back and the water is really murky almost milky. I have never seen this before.

The fish did not seen to be stressed, or at least there is none that I could observe.

I am going to do a water test now and then need to decide if I should change the water again.

Not sure what to do.
