Hello Revhendrix,

We just completed our conversion over Memorial Day weekend so my advice will be from a satisfied newbie to a "new" newbie!
In answer to your questions, I think you will only need the Clorox (6%) but buy a lot. We have a 14000 gal IG Fiberglass and we used about 65-70 gallons. We found that by testing it every 2 hours (since we were home) and keeping the FC at 15ppm (free chlorine which you will test with the FAS-DPD kit) the conversion went extremely quickly (started on Friday night, were in the pool on Monday afternoon!) We tested and added bleach every 2 hours to keep it to 15ppm. (Make sure you continue to backwash the filter, watch the pressure, if it builds, it is getting restricted with the "gunk" from the pool. We backwashed several times per day.) When adding the bleach, be ready, the color and cloudiness will shock you the first 4 times (minimum) you put bleach in the pool. I guess you could use the shock from the pool place but it may have other ingredients or solids in it that you do not need. The bleach worked EXTREMELY WELL!!! We put the bleach in with the filter running normally, pouring it at the return to the deep end. Your goal is to keep the pool chlorine level at 15ppm till it maintains that reading overnight AND to have a CC (combined Chlorine) reading of 0. Once you achieve that, you can add your stabilizer and that is where the sock comes in. We put ours in an old white cotton sock and tied it to the "eye" that the rope between the shallow and deep end goes through. That worked just fine, took about a week to get all dissolved. As far as harming the vinyl, I have seen other threads on this site regarding that and it seems that 15ppm will not harm the vinyl (anyone can correct me here if I am wrong on that issue). Changing the sand is not difficult, but if it was changed last year, I doubt if you need it changed. You can ad a little Diatamatious (sp) Earth (DE as it is called) to your sand filter, that will help it get smaller particles out of the water.
You will not be sorry you are doing this, we have never (I repeat NEVER) had water so clean and clear!!! I cannot say enough about finding this site!
Looking at your ph, it does look a little high since other threads here have said that ph a little lower works best with the CLorox level. Ours during the conversion was about 7.2-7.5. When we started this, we knew NOTHING about what the water chemistry should be and I was extremely overwhelmed! I had Ben rush ship a kit and BOY WAS THAT WORTH IT!!! In just a few short days, I feel I learned what it takes to get the water right and how to test it to make sure it is right. I learned all the acronyms (i.e. FC, CC, TC, ALK....etc) all of which I knew none of. I was amazed how quickly I understood it all once I got the kit and started testing.

Good Luck and keep us posted. Give it a few days, it is SOOOOO worth it!
