Ok. Just to get caught up. I took all the rock out of my main display and put in 25 gallon brute trash cans. Then removed all the sand and put the in brute trash cans as well. Once everything was removed. I filled the aquarium with fresh water and vinegar and rant for several hours. It took about a couple hours for it to get the calcium off the back glass. The overflow was bubbling with killy worms and the same thing for inlet into sump. Here is pic of tank with vinegar.
