Pool Shock by Aqua Org - 65% Granular Cal Hypo - Swimming Pool Shock for In-Ground, Above Ground, Spas & Hot Tubs - 55 Pound Pail

Great price for Hypochlorite Shock. Does not come with a scoop but I had a couple from other product purchases. The only down side is the top is not easy to remove and has already developed a crack. It is still secure. On another note, be careful when removing top. Hold your breath. Otherwise the Chlorine gas buildup will get you...I found out the hard way!

price of product is way cheaper than going to a pool store. product needs to be diluted and allowed to disolve in 3-5 gallons of water before adding to your above ground pool.

I would like to echo the comments from most customers with the hacks to workaround the shortcomings.1. Horrible lid and a badly designed tab that required heavy duty screw driver and piler to remove. It is worse than the driveway sealer bucket. Good hand exercise though!2. The plastic bag inside the bucket to hold the chlorine shock corroded and broke into 2 pieces. There goes the moisture seal!3. The lid is from the 19th century press seal type. It seals tight but very hard to open on a weekly use basis. Have a heavy duty screw driver handy to do some hand and finger exercise. I'm thinking about transferring all the shock powder to an empty bucket with a screw type lock lid for 21th century use.4. There is no scoop inside the bucket. Again, save the old one or use an old measuring cup.5. No mention of available chlorine on the label, the listing said 60%. So, use more since it is cheaper.6. Probably no stabilizer in the shock, need to buy it separately! There goes the saving!7. The sturdy wire handle may not be a bad thing, at least it won't break like the plastic one. Put a slit opened short PVC pipe on it or wear glove.8. The shock dissolved quickly in a 3-gallon bucket of water than other famous brands I used before. It leaves almost no residue which is a good thing and won't hurt the liner as much.Overall not a deal breaker but there are things for improvement going forward. Keep the price low, that's all it counts!

Product does not dissolve well. Leaves water cloudy for hours. Lid on bucket is pressed on. Hard to remove and reseal. Granules are large sized and packed in heavy plastic bag. Twist to reseal. Did not have problems dissolving with the other brands packaged in one pound bags. Will not be saving money again with another purchase.

This shock dissolves quickly and doesn’t contain stabilizer which can lead to chlorine “lock”. Container can be difficult to open but not as difficult as some other chlorine containers I’ve had in the past. The really cool thing about this chlorine is that the granules are in a plastic bag within the buckets so you have two opportunities to ensure that the product stays dry and airtight. If you’re new to pools and chlorine, this is important! I made the mistake one year of not ensuring that the container (another brand) was not tightly closed (mainly because it was hard for me to open) and left it in my shed over the winter like that. HUGE mistake. When I went into the shed in the spring, the chlorine smell was AWFUL and worse than that, everything in the shed made of metal was totally corroded. Lesson learned $$$Anyhow, to make reopening the bucket easier, I use the flat end of my corkscrew. Works like a charm. You could probably also use a paint can opener.Price was EXCELLENT, delivery quick and the product works. Enjoy your pool!
