1 Ounce Of Dichlor = ?ounces Of Bleach


Recommended Posts

Simple question, having a bit of time finding the exact answer....How much Clorox bleach, in ounces is the same as 1 ounce of Di-chlor....Richard, I am sure you know this off the top of your head.

One oz dichlor is approximately equal to ten oz 6% chlorine. More exact.....0.86 fl oz 6% Chlorox equals 0.09 oz dichlor at 60% available chlorine. It will vary slightly if using 56% dichlor or 62% dichlor.

The precise numbers depend on the true density of Dichlor, which varies, and as Tony says it also depends on the kind of Dichlor. I have generally been assuming a density for Dichlor that roughly translates to 1 ounce weight being 1 fluid ounce volume. When that is the case, then one ounce of Dichlor dihydrate (55.4% Available Chlorine) is the same as 8.6 fluid ounces of 6% bleach (6% is a weight percent of sodium hypochlorite; Trade % is 6.2% which is the Available Chlorine by volume; Available Chlorine by weight is 5.7%). If the Dichlor is anhydrous (the pure stuff would be 64.5% Available chlorine; it's often quoted as 62% because it's not pure) then 1 ounce of Dichlor would be the same as 10 fluid ounces of 6% bleach.

The dihydrate form of Dichlor is usually the more common one since it is designated as a class 1 oxidizer (an oxidizer that does not moderately increase the burning rate of combustible materials with which it comes into contact) whereas Dichlor anyhydrous is a class 3 oxidizer (an oxidizer that causes a severe increase in the burning rate of combustible materials with which it comes contact). Cal-Hypo that is greater than 50% is also a class 3 oxidizer; when < 50%, it's a class 2 oxidizer (an oxidizer that causes a moderate increase in the burning rate of combustible materials with which it comes into contact). Trichlor used to be considered a class 2 oxidizer, but was reclassed to class 1 a few years ago. None of these are a class 4 oxidizer (an oxidizer that can undergo an explosive reaction due to contamination or exposure to thermal or physical shock, and causes a severe increase in the burning rate of combustible materials with which it comes into contact).

One ounce of Dichlor dihydrate is also equivalent to two fluid ounces volume (actually, 2.7 ounces weight) of MPS non-chlorine shock assuming typical purity containing 43% monopersulfate.

Thanks both for your info. Trying to do a simple laymans cost comparison of bleach/borates and dichlor...leaving CYA out of the equation right now.

You might look at this post I made that compares the cost of various chlorine sources. Dichlor tends to be quite a bit more expensive; usually around double the price of Trichlor which on first appearance is the least expensive source of chlorine (but when factoring in pH Up or equivalent, it's not). Roughly speaking, Dichlor is 80% more expensive than 6% bleach, though this varies a lot on specific bleach prices.

The Borates will be a one-time per refill cost. It's also likely that one will be able to keep their water longer between water changes with Dichlor/Bleach than Dichlor-only, though it's hard to say by exactly how much so the "fixed" cost for the Borates and other start-up chemicals could be lower (spread out over a longer time).

If one doesn't get their pH under control via lower TA, then the cost of acid would need to be added.
