Sometimes brand name bleach features a stronger concentration of chlorine and some super cheap one has other salts that you shouldn’t be adding to you pool, a couple of leaky caps which might end up hurting you. So, carefully inspect the container, check the label for contents and purchase the cheaper one. You are going to dilute it anyway.
CHLOROX (BUY ON AMAZON),
Regular bleach (BUY ON AMAZON)
Ultimately, the brand name really doesn’t matter, it is the percentage of sodium hypochlorite in the bottle that matters.
The normal ratio is 6%. If the ratio is not shown on the bottle it is less than 1.15%. Even name brands will have sales of watered-down versions of their own brand name for sales, so always read the label.
Getting a gallon of discount bleach for a buck actually costs more than paying 3 bucks for the 6% name brand, it takes over 5 bottles to equal 1 bottle.

Clorox Vs Generic Bleach
Household bleach (also known as chlorine bleach) is a common name for the generic version of Clorox, which is typically used to remove stains, clean and do laundry around your home.
Chlorox is a little more careful to make sure they are always full strength, while some of the discount brands (or generic chlorines) out there vary a little more, but they are mostly always close enough so that’s not a deal breaker. The normal ratio for Clorox is 6% so If the ratio is not shown on the generic bottle it is less than 1.15% which sucks!

Similarly, there have been some few reports that discount brands raise PH more than it should, but I have never faced such issue before in my life.
Personally, I don’t think there is need to pay the extra buck for a brand if the generic one meets all requirements.
Note: Be careful with the dollar stores, super-duper discount stores, etc. In most cases, it is either the bleach is old and weak or simply started out weak to begin with.
