Why no one wants Cal Hypo?

Why no one wants Cal Hypo?

GiggaWat

Cal hypo is typically more expensive than bleach and also increases CH which can add up over time. It’s long term less problematic to use bleach than Cal Hypo but in a pinch, it’s fine.


slow_connection

Sure it raises your CH, but only trivially. Cal Hypo also has a much lower pH than bleach, which means you use less acid and can more easily keep your pH under control which saves money. Furthermore, keeping your pH under control means you're keeping your alkalinity under control, which saves more money. I've been out of the industry for a few years, but back in 2015/2016 bleach and cal hypo (at least in bulk) were about the same price.


GiggaWat

I agree, and you're correct. It's a trivial addition.


churningmesilly

Yeah so it’s my sense people may be overlooking this wonderful product. The marketing guy at Hth needs to step up.


slow_connection

It's usually marketed as shock, I'd say 99% of pools that use cal hypo as their primary means of chlorination are commerical. Residential stores always recommend trichlor bc it'll fuck up your CYA and keep you coming back for more shit to kill the inevitable algae


churningmesilly

That’s why I ask. Shelves are fully stocked with them. Not sure if they did better with their supply chain or demand is bad. Clorox shock is expensive and has long term implications (cya) but those are nowhere to be found. Just seems people are not buying Cal Hypo when they are happy to buy Shock with CYA.


GiggaWat

Yeah it’s odd but glad you’re asking the right questions.


mulberrykid

What’s wrong with shock with CYA just need to make sure not to over do it with anything that has CYA


bulldozer6

I suspect they're asking because they can't find other options. Sounds like the only thing they can find is cal-hypo and shock. Keep looking for liquid chlorine!


churningmesilly

It’s not a sustainable solution and CYA shock is extremely out of stock (in store and online)


mulberrykid

Oh I see I was confused I thought maybe I was using the wrong thing haha


Trav116

I was talking to a pool guy last week. The plant that produces something like 50% of the country’s supply of chlorine tablets burned down recently. So you’re seeing the results of a supply shortage.


USMBTRT

I've been using cal hypo for years and love it. I've never had a big issue with my CH creeping, but splashing kids and winterizing every fall help a lot with water turnover.


churningmesilly

Still don’t see a reason for this disparity. To summarize: 1) Out of stock are all of the below for which only one is a known supply constraint (i.e. pucks due to fire) Liquid Chlorine, Pucks, Clorox Shock 2) What is not out of stock and is full on shelf is Cal Hypo. 3) Why are people choosing to not buy Cal Hypo even though all other chlorinating option is not available? Or is the Cal Hypo company just so much better in supply chain and that they keep in stock while people are buying it up?


interested_sortof

Could it be based on location? In AZ, (at least in the recent past) I and others avoid cal-hypo because we already have pretty hard water with a high calcium content. Preferred to avoid adding more. Like CYA, the remedy is a partial drain to remove it. So perhaps you're in an area with hard water as well?


mattvait

Cal hypo is not stabilized so no cya. Never noticed an effect of calcium levels even when used with the old method of daily addition. Cal hypo does add undisolved solids to your water and you will see some sediment. But it's the original and there's nothing wrong with it per se


swerve408

I had someone on Reddit die on a hill saying pucks/tablets were superior to liquid. I don’t think he understood the concept that liquid chlorine doesn’t “burn off” quick if there is an appropriate amount of CYA. And CYA does NOT leave your pool unless you physically drain or dilute the water /u/noahdrizzy try explaining yourself

swerve408

You’re the one who told me tablets with cya were superior over liquid haha don’t get all angry because someone called out your bs. The fact that your so upset about your wrong chlorine choice says a lot!

Settle down kiddo

Cal hypo raises your Calcium faster


churningmesilly

Faster vs what? I don’t think Calcium rises on its own.


stillwaters23

In areas of the country where it’s hot and fill water has high CH (like the southwest), then it does rise on its own. As water evaporates from the sun and heat, the calcium gets left behind, and refill water adds more calcium, and the cycle goes on until you replace water. So cal-hypo just makes it worse. In the eastern (wet) side of the country it’s not a big deal, because fill water tends to be softer, and the rain exchanges some water, as does closing for the winter. Also a lot more use of vinyl in pool construction which is less sensitive to CH.


TNT21

There was a fire at a major tablet/puck manufacturer. I dont think that effects the liquid bleach manufacturing/supply. Yes more people probably prefer to use tabs in the float but it think its more of a supply issue not that people dont want liquid chlorine.


bulldozer6

Supply for liquid chlorine wasn't affected but it's demand is probably up due to difficulty finding tablets...next thing you know liquid chlorine is harder to come by.
