Hi Dave, it sounds like your tank hasn't cycled properly due to the high nitrites, which is probably why the fish have white spot due to stress.
After the 50% water change you do today, you will need to do around a 20-25% water change every other day, which will help to reduce the nitrite level, and also put some good elements back into the tank water.
Also do not stop the filter, or clean it unless absolutely necessary as the bacteria culture will have to develop inside the filter, which will in turn reduce nitrites, and aerating the water with an airstone will help reduce the nitrite level.
If the problem persists later with the white spot, then I would add a mild white spot treatment such as protozin.
