Finally think I have this tank sorted.
Long story short, we went away about six weeks ago for five days and left the sister in law to feed the fish. Because of the heat at this time of the year and the fact that we have two aquariums in the man cave which is on the top floor of our house we have ceiling fans installed to help cool them.
When we got home at about 11.00pm the smaller of the two aquariums was more like a pet cemetery, which I could smell as I walked in the front door downstairs. The fan had been turned off, multiple dead fish (which appeared to have been dead for days), mountains of food in the tank and the water was hot and white.
Unbelievably the big Angel fish and a number of others were still alive.
Emergency water change that night and a total tank overhaul the next day. For weeks any other fish I would introduce would die in a couple of days, now after numerous water changes and filter cleans all appear to be happy and healthy
The aquariums are a big part of the man cave and it was driving me nuts.

As you can see the aquariums are a big part of the room.
