The difference between 40 and 60 ppm is within the testing error of most CYA tests, although strip tests aren't that accurate.

Take a look at the Best Guess chart in my signature below. With a CYA of 40, you'll want to maintain your chlorine levels between 3-6 ALL the time. If you drop below 3ppm, you risk an algae bloom. So, each evening, add enough bleach to get back to around 6. If you find at the next evening's testing that you have dropped below 3, maybe go just a little higher for the evening dose. (Maybe try 7.)
Gotcha...I will keep you in the loop on this.....Algea scares me...
Guys and gals....
This BBB method, is awesome! A few questions....
1. My water is in perfect shape per my taylor 2006c test kit (CC, TC, PH, CYA, etc).....So, how often do I need to shock? 18,500 gallon pool, means to my fuzzy math......1 gal bleach=6 ppm on a 10,000 gal pool..so I need...6 gal of bleach to get above 15ppm on my 18,500 gal pool?
2. Water softener? Thoughts? Ideas? Am I retarded? The guy who installed the pool put something in the pool and it made it feel silky smooth....no idea what it was.....
3. I can not find polyquat 60% here in DFW? Any ideas?
4. Anyone use this for a timer on their pool pump...http://www.honeywellcentral.com/prod...-timer-ti1062u

#1 - On your pool, 1 gallon = ~3 ppm chlorine
#2 - It's a matter of perception, but to some people, pools with salt feel that way. Borax also has somewhat similar affects, once you start getting above 50 ppm borates.
#3 - It's getting hard to find locally; it's still available online.
#4 - You'd better watch the inductive (motor!) load limit. It is listed for a 1HP motor max, but my experience has been that consumer grade electronics don't do well when you max them out.

When should I shock the pool? Once a week? After heavy usage? What do you all do?
Many thanks in advance..

Most of the time, I only shock when CC is > .5 but I will shock after a very heavy rain storm. If you are able to keep your CL in the recommended range (Ben's chart) you may not need to shock very often at all! Good luck.
10,000 gallon IG vinyl liner pool, BBB user, salt added to 2300 ppm (because it makes the water feel great!), new liner/new water on 6/23/11, algae-free since 2006 (at least that's as far back as I remember). 1HP Hayward 2-SPEED CONVERTED Superpump, Hayward sand filter, PS234 test kit.
Goal: To remain completely algae-free for the life of this new liner!
Life lesson: It is what it is.
