Features
- POOL SHOCK TREATMENT - Rx Clears Super Shock contains 68% calcium hypochlorite, yielding 65% available chlorine making this similar to Mega Shock, but slightly less concentrated. This shock will raise your free chlorine levels, water hardness, and pH levels giving you crystal clear water for a more enjoyable swimming experience. Due to its high percentage of chlorine, Super Shock is very effective and efficient for a quick chlorine boost.
- MIX BEFORE YOU FIX - It is best to dilute Super Shock in a bucket of water before dispensing it around the pool which can prevent liner staining and cloudy water. Add this powder to a bucket of water before you add it to your pool. Add a 1 lbs bag per 10,000 gallons of pool water.
- POOL SHOCK WITH ALGAECIDE - Kill the algae in your swimming pool by adding 3 bags of shock per 10,000 gallons of pool water. Rx Clear strives to provide quality products for a safer, cleaner, and more enjoyable swimming experience. When it comes to correcting your swimming pool, Rx Clear does it all giving you crystal clear water that fits your needs.
- WORKS BEST AT NIGHT - For the best results use Super Shock at night in order to prevent the sun from eating up the shock since it is not stabilized; its best to shock when the sun isnt out for maximum performance. Do not swim for 8 to 10 hours after application.
- POOL CHLORINE SHOCK - Maintain your swimming pool or spa with reliable pool chemicals and treatment supplies that you can depend on from Rx Clear. The Rx Clear brand is the premier choice for a trusted cleaning product to keep your pool in its best shape.

My grandson came to swim in the trunks he had in the lake. I got the worst case of dark green algae. I threw everything at it for a couple months. I thought I had it gone and he being 4 threw a toy that hadn't been cleaned back into the pool. Instantly got it back. So I bought this at the end of the season and it worked hard and fast. I was so impressed I ordered 12 packages and got a 6 months subscription. Lol. I have 24 packages so I'm ready. It's a 30'x52" pool. I purchased for this year suits and trunks and a life vest that all stays here so it doesn't happen again. Lol Thank God I found this one.

For the first time in 25 years, the pool developed mustard algae. Used 3 bags one evening, one the following evening and it’s gone. Of course, there was the obligatory brushing, vacuuming, and filtering for 36-48 hours, but it is now perfect. I changed the filter each day, not wanting to breed more algae only to add it back into the pool. It takes time and effort, but it was worth it. Did I mention I live in Southern Arizona? The pool allows for outdoor time, and helps to lower body temperature, along with being relaxing.

Pool chemicals were getting hard to find this year towards the end of the summer. Most of the local shop were either out or the prices were so high, we just couldn't afford it. Amazon came through again. I was able to buy just the right amount at the right price. I prefer the 73% calcium hypochlorite. But for what I needed this 68% did the job.

I would buy this again. I have a 15 inch round 52 inch high pool. I only need one pack per week to maintain the chlorine even in the hottest weather. The store said use 1/2 a pack but the heat wave was eating up the chlorine so we bumped it up to 1 pack on Sunday and have had no problems since. Works great! I use it along with my algae killer once every 3 weeks and if the ph needs to be bumped I would use baking soda but so far had not needed to do that.
