Hello,
We have a new (to us) home in Tucson AZ with a 11,000 gallon pebble tec pool. When I first moved in a friend helped me with the chemicals but we quickly learned that the CYA was above 120 so last month I drained the pool and restarted. I believe that the former owner had used the stabilized tablets (dichlor/trichlor?) exclusively and this caused the high CYA.
Ok, now for the question: I want to make sure my pool does not drift into high CYA again. For now I have been using them to actually bring up my CYA and bring down my Ph and this has been working well. I'm right about where I want to be now for the levels and want to know what the "Braintrust" thinks about the use of the four chlorine types:
The NST Tables are 10.5oz each. A 24.5lb Bucket of them gives you approximately 37 tablets. At $125 for that 24.5 lb bucket you are paying ~ $3.37 per dose.
Can anyone shed some pros and cons of these?
Thanks much
Rob Z

I'm right about where I want to be now for the levels and want to know what the "Braintrust" thinks about the use of the four chlorine types:
- Diluted chlorine liquid (walmart, etc)
- Stabilized tablets (dichlor/trichlor)
- NST tablets which are ~ 70% Calcium Hypochlorite
- Calcium Hypochlorite powder (~ 70%) .
- Keeping in mind that I am concerned about the stabilized tablets but I understand that they will work well when I travel I would like to refrain from using them for normal maintenance.
- The NST tables are very expensive and when I compared the active ingredients the NST Tablets are ~ 70% Calcium Hypochlorite.
- Why not just buy the powdered Calcium Hypochlorite (like Power powder plus from Leslie's) or (CALCIUM HYPOCHLORITE POOL SHOCK BUCKET from inthewswim.com. Then I could use my Stabilized tablets (dichlor/trichlor) when I'm on vacation?
