When I worked at a municipal pool, we used Chlorine Gas in 4 foot steel bottles. It was evil stuff. You need test equipment so you don't over dose the water.

Pump 635 impeller shaft is
Here is a simple solution to your shaft impeller problem. First, you need to buy a brass (non-ferrous) round bar about 1/8 inch thick. Any other metal types WILL NOT WORK. Cut about 4 1/2 inches from the brass bar and verify it will fit in the impeller. If it does not, then you need to re-size it. The best way to do that is place it in a drill press and use a metal file (the reason for the 4 1/2 size). As the brass bar rotates, press the metal file against it until a desire size is reached. You may have to remove it from the drill press from time to time and see it will fit into the impeller. When the correct dimension is found, place it back in the drill press and use a medium grid emery cloth to smooth it down. Remove it from the drill press and cut it to the proper size (3 1/2 inches). Remember to round out both ends smooth before re-installing it back in the pump. Reassemble as normal and you are done!!! This should take about 30 minute to perform including installation. I did this to my Intex pump and it runs very smooth and have not problems with it.
Impeller in intex model 635 broken where can I buy replacement part?
A late answer but it might help future Intex impleller sufferers... they do not sell replacement parts and you won't find any impellers sold separately anywhere on the planet. I've had 1 Intex pool and 3 Intex filter pumps in 3 years. Last week the 3rd pump's impeller broke as well. I shan't buy their products again.
I need an impellor for
Hard to find!! I would buy a new one if out of warranty.. Around $48 new at Amazon.. $20 used ebay..
Good luck!
Intex pump strongly pulls water
It is likely that your filter is dirty. The filter's cartridge can be removed and cleaned with a spray nozzle on a hose. you will then need to reassemble, prime and restart. I hope this helps.
