I don't remember seeing anyone say that there was such a thing. Why aren't you considering simply using bleach?
There is a cal hypo product in a different form that does not have cya but its not used the same way as the trichlor pucks and you CANNOT mix trichlor with cal hypo - yikes.
If I am going on vacation for a longer time without someone to babysit the pool, I will clean well, superchlorinate/shock, cover and set my pump timer to run longer than usual. I have never had issues.
I use bleach while at home, but Im going on vacation and have no one that can care for the pool. I want to put some tablets in my chlorinator so I can atleast have some chlorine level while away.I will leave th pump on low 24/7 while gone. My current cya is 70 and I dont want to raise it. I thought there was a form of non stablized chlorine that came in tablet form.
Thanks
John
Yep, nothing out there. How long will you be gone? Maybe just shock, cover and run the pump. Hope for the best if you can't get someone to come over. If its short term, my guess is the pool won't suffer much except lower chem levels when you return. Keeping debris out of the pool with the cover on will help.
Try piercing a tiny tiny hole in a jug (or a few) filled with bleach and leave it floating. It may dispense enough to get you through.Quote:

There are two types of Cal-hypo tablets that do not add CYA to your water and are supposedly slow-dissolving. Both are sometimes called "Duration".
One is wrapped a plastic capsule that you then dispose of. Get this type.
The other is not and will dissolve in a skimmer in a matter of hours, and block the skimmer...Guess how I know! Don't waste your time or money.
HTH used to make the plastic type but now makes the caplet. There is a sister brand that I can never remember the name of that makes the plastic capsule.
Again, that's what you want, that plastic-wrapped Cal-Hypo capsule.
Looks like I'll have try this method, Im going to be gone for 8 days so if I do nothing I will definately be at 0 colorine by the time I get home. Im leaving my solor cover on to keep out as much crap as possible.
Back to the Tablets - I should know this, but whats the difference between dichlor and trichlor? I thought one was not stablized and the other was?
Thats the reason I like the BBB method - simple and easy to understand.
Thanks for all the help

Almost all the tabs are Trichlor now AND just recently a lot of them have copper in them as well. The dichlor tabs are around some places but not anywhere I have looked recently (and I HAVE looked) The difference? Ummm...I know this one but it escapes me. Two vs. three (di vs tri) chemical compounds/active ingredients - the chlorine, buffer (cya) and other ingredients like copper (to act as an algaecide) not counting the inactive filler crap some have. Thats my best guess off the top of my head, but I bet if we look it up on the site, its here somewhere. Chemgeek?
Tri-chlor & di-chlor both have stabilizer. The difference is tri-chlor also has a "clarifier"
My understanding is -
Di-chlor has Chlorine and CYA
Tri-chlor has Chlorine, CYA and Acid
Dichlor and trichlor are both stabilzied chlorine (chlorinated isocyanurates). Trichlor has a pH of around 2 while dichlor has a pH of around 6 so both are acidic. Trichlor is slow dissolving so it is suitable for forming into tablets for use in erosion feeders. Dichlor is very fast dissolving so it is sold in granular form and is not really suitable for use in erosion feeders.
Dichlor adds more CYA to the water than trichlor. For every 1 ppm of FC added dichlor will add .9 ppm of CYA while trichlor will add .6 ppm.
Hope this helps.
Edit: some companies will include other ingredients such as copper sulfate as an algae preventative, clarifiers, sodium tetraborate (borax) as a pH buffer, etc. into their formulations of these products but these have nothing to do with whether it's trichlor or dichlor. Also, the number of chlorine molecules attacted to the cyanuate structure determine if its dichlor or trichlor. Dichlor has two and trichlor has three. This is why dichlor puts more stabilizer in the water then trichlor for a given amount of chlorine. There is one third more chlorine in trichlor than in dichlor.
Sorry, this is just plain wrong. See Waterbear's explanation.Quote:

If your CYA is high, using Tri-chlor while you are away will send it through the roof.
When I'm away, I have someone dump 1 gallon of bleach in the skimmer every other day and that's all I need. I have the pump on a timer, and leave the solar cover on. So all my father-in-law has to do is dump in the bleach every other day.
I knew someone would show up with the right explaination! Thanks.
That's what I always thought. As my mom used to say...That's what I get for thinking! :p It didn't even dawn on me to think about the di & tri chemically.Quote:

Actually saw some cal hypo pucks at wal mart neighborhood store. I'm thinking of using these when I go away on vacation.
Every 1 ppm Free Chlorine (FC) you add from Cal-Hypo will increase your Calcium Hardness (CH) by 0.7 ppm, but that's not usually a problem and represents a much smaller percentage increase in typical CH levels (i.e. the 0.6 ppm increase in CYA from Trichlor out of 30 ppm CYA is 2% while the 0.7 ppm increase in CH from Cal-Hypo out of 300 ppm CH is 0.2% or one-tenth as much).

There is another Cal-Hypo 3-inch puck available under the Sustain name. I travel frequently and use this product for my daily chlorine use. I do use bleach to shock but find this puck helps me maintain my chlorine level while I'm away. The puck is not wrapped in plastic and does not erode in a day or two. Every bucket comes with a plastic dispenser and a sliding lid. It holds two pucks, which usually last approximately one week. Sustain also makes other products for shock, clarifying, etc. but I don't use any of them. I'm a BBB kind of guy who uses these pucks to maintain my chlorine without stabilizer. They have a website at www.askjoepool.com if you want to locate a dealer near you. I'm not in the pool business! I live in CT and my login name should give away what biz I am in! Cheers! :)
