We have a salt water pool and have had problems two years now. The chlorine level is reading high, ph is fine and salt reading is at 2800. I have noticed a lake smell from the skimmer basket. Are there any really good test kits that anyone would recommend. We replaced the salt generator last year so I know it is working. Everything seems fine but I do not think the pool is at optimal conditions. The bottom of the pool is slippery like we are getting some form of algae but you cannot see anything. Any advice would be appreciated. Thanks JB
