sodium or calcium hypochlorite

[stepowell7]

guys,

I am looking to supplement the tablets I am using in my 17000 gallon pool.
I am using liquid chlorine with is 12.5% sodium H/C.
I am wondering if a 1lb packet of shock containing 68% calcium H/C is cheaper/ more conventient and will add more chlorine to my pool. I think 1 packet would be enough just to supplement my chlorine.

Thoughts ?

or do I have this wrong and should be comparing liquid chlorine to Concentrated Chlorinating Granules . If that is the case am I getting more for my money with granule over liquid chlorine

did you read the BBB method yet?

the reason for the BBB method is tablets usually puts in too much CYA and it could take a lot of
chlorine to shock.
if CYA is low enough just a small amount of chlorine is needed to shock the pool.

If your pool needs additional Calcium or Cyanuric Acid, then Cal-hypo or dichlor might be an economical solution. Without knowing your test results, there's no way to tell. Maybe you're already too high on CYA or CH? You could end up making a bad situation worse, which is no saving at all.

This article in Pool School will explain the advantage and disadvantages of the various forms of chlorine.

Without information on the cost of each source of chlorine, we can't answer that. Other factors also come into play, such as your current CYA & CH levels and what type of pool surface you have.

Chlorine is chlorine is chlorine. Depends the unit cost and if you want the byproducts in your pool or not.

This would really help us answer your question. All forms of chlorine will sanitize the pool. The determining factor as to which form of chlorine is best for you starts with determining the current CYA and CH levels of your pool water.
