Feeback on HTH Chorinating Modules at Walmart

I was looking for feedback on HTH Chorinating Modules available on walmart.

I found the Dichlor recommended in this thread at Amazon, but it will be 2 to 5 weeks before it is shipped!

I was hoping to get by on the HTH modules in the meantime, unless there is some major issue I should be aware of.

Thanks,

We don't recommend the HTH product.

Do you have current water testing results taken with a drops-based kit? Specifically, do you know what your CYA (stabilizer) level is?

What kind of pool do you have and what is the volume?

Welcome to the Pool Forum, by the way!

Try this link -- at least in the east, this is available immediately

Kem-Tek Pool and Spa All-in-One Concentrated Chlorinating Granules @ Amazon

Note that this is the 5# size; other sizes should show up as well. The 25# size is also available, but the 12# size shows a 2+ week wait.

We're finding it VERY hard to locate un-diluted dichlor. The only reliable local source we've found is Sams Club. The dichlor they sell (24 1# packs or a 50# bucket) is at an excellent price, if available. The dichlor commonly sold at Kmart, Walmart, Lowes and Costco, as well as at most pool stores, is blended or diluted.

In some markets, Home Depot sells the same Kem-Tek product you'll see if you follow that link. If you can find that, it should be OK, too, though probably no cheaper than Amazon.

The "HTH Chlorinating Granules" (your link) is calcium hypochlorite that is heavily diluted with magnesium sulfate (Epsom salts) (MSDS at Home Depot)

I can post the complete the pool test form when I get home (at work now). I have the HTH 6 way kit (with the Taylor K-2006 on order). When I tested after initial setup (bleach only), the CYA test didn't register. By that I mean the solution was supposed to turn cloudy and at some point obscure the black dot in the bottom of the vial. The solution was practically clear and a full vial had negligible effect on the visibility on the dot.

My Cl levels tend to be at the bottom of the scale in the evenings (before adding chlorine) and at the top of the (HTH) scale in the mornings (~5 ppm IIRC). My pH is currently around 7.6 after a couple of treatments of Borax. It had gone from bottom of the scale to 7.8-8 after my first treatments, but I've been letting it set a couple of days with no new Borax.

Intex easy set (inflatable top) 15'x48" ~5000 gallons. ((15/2)^2 * 3.14 * 4 * 7.48=5257.62 )

Thanks, the Super Simple Pool Chemistry Recipe thread was a great help getting me started.

As I indicated above, I grabbed a 2# container of the HTH Chlorinating Granules for PoP-Up Pools (along with several gallons of Clorox and Borax) from Walmart when I got started. That's running out quick hence the search for a longer term dichlor solution.

Thanks!

Ben gave you some links above that may help. You won't want to use dichlor indefinitely, however. Only until your CYA is around 50 or so. Then, you'll want to switch to bleach so your CYA level doesn't get too high.
