Starting resurfaced pool

[Kidney]

Great info PoolDoc!

2) So with all forms of chlorine adding some salt, no need to worry about rust with bleach then ;-) Re CYA biodegrading, I will keep an eye on it anyway and can add as needed. I just don't expect much loss if maintenance of FC level prevents slime.

3) To evaluate the LSI, I have so far used the watergram wheel in the K2006C kit *and* the water temp provided on the display of my Hayward H400FDN heater. I wonder what this temp really corresponds to now that you're mentioning this. I believe it is really close to what the temp is in the pool. Based on your explanation, I understand I only need to adjust the temp reading at the heater by +20 when it runs. I will take a look at the LSI calculator.

Re vacation/away time, I found a procedure about this on the Super Simple Startup Recipe page that does use polyquat. I guess this is what you were referring to. Interesting.

Re protozoan cryptosporidium, I found the procedure apparently from the CDC to fight it at this link: http://www.floridahealth.gov/healthy...ponse_reco.pdf

2) You could take it that way, but it's not what I meant.

3) The LSI value that matters, with respect to your heater, is the LSI of the water 1/32" of an inch away from the interior of your heat exchanger pipes . . . and yes, THAT water will be at a higher temp than your pool water.

4) I'm working a vacation page. Polyquat can be a helpful tool with any approach. Basically, your options (which can be combined) are: use a feeder, use a floater, use an SWCG, use polyquat, maintain borates > 60 ppm, maintain phosphates < 100 ppB, follow HiC2 (high CYA + high chlorine) and raise FC > 30 ppm before leaving, cover your pool.

The crypto guideline has been updated since I last saw it. It was amusing to see how closely it aligns with what I tell guards: "It's not the nice t##d that will make everyone sick; it's the disappearing brown cloud!". Then, I usually 'share' with them information about a black bear's first meal after hibernation.

PoolDoc:

2) Not sure I understood you. Do I need to worry about the salt that bleach adds and/or disappearing CYA?

4) I'll be glad to read your vacation page. Hope I don't miss it especially since I'd like to learn about borates and phosphates. That Phosfree product at Leslie's really has me wondering what benefit it could have....

5) I have CC and its level could rise. How do I get rid of it? increase TC 3 to 4 times my FC reading or in some other way?

If there are more current guidelines re crypto, it would be great to know even if there are no bears in sight here 8-D

Actually, the BEST way to manage the risk of crypto in YOUR pool is to keep anyone who's feeling a bit loosey-goosey out of the pool. Instead, send them to the bathroom with a magazine and a bottle of loperamide (plug-em up) pills.
