well just changed the substrate in my mbuna tank to sand as gravel isnt best for them here is a few pics of how i did it.
started with this.

Step one catch and bag all of the fish and float them in the bath in water the same temp as there tank.

step 2 remove all filter media and rock work from tank and place in 80ltr dustbin.

step 3 start to drain off all the water from the tank into the 80ltr dustbins i used 3 to drain my tank.

Step 4 remove all old gravel and replace with new cleaned sand sorry didnt take and pics of this add rock work water and fish and the all done hey presto and here is the finished article obviously it will clear up in there over the next few hours.
