Bleach Question during Conversion

[SPILL]

Thanks for the response, Grace. Things are looking up, I have been relentless in the testing and shocking, using only 6% bleach. Today the water is Mt Dew green but clearing - I can see the bottom. Also the filter seems to be flowing better. I would highly advise anyone doing this with a DE filter to change the medium at least once during conversion. DE is cheap and it does capture a lot of gunk. I have been careful not to add too much bleach at once to avoid any negative consequences, been through 14 gallons and I figure will need about 6 - 8 more to complete the job.
Question: Once things clear up, to get rid of the CC will I need to shock to whatever the CC level is? e.g. Baquacil is gone, cl holding at say...2. but CC is 15, I assume I would need to shock to 15? For how long? Only then will I add CYA to stabilize...and replace DE once more.

You're probably going to need more than another 6-8 bottles of bleach! I've been at it dumping bleach since Sunday afternoon and it's a light cloudy shade of green now. I must've dumped 20-25 gallons of 6% bleach and one large bottle of 12% pool store shock/bleach already! I'm still not there.

I'm going to Leslie's pool on the the way home and getting 3 more industrial strength 12% bottles of bleach. It's about to rain heavy tomorrow and I sure don't want all my work to go to waste because of the rain....

Good luck with your conversion! Hopefully we'll get there soon!

I did amy own conversion 6 years ago, and I helped someone with a conversion two years ago. The most important thing is to Keep your free chlorine in the shock phase. Forget about the cc - it isn't the effective chlorine. You must test the chlorine at least 2x a day - more if you can and keep the chlorine at shock level. Most important is to get the chlorine up at night when the sun goes down - and if the sun is strong try to get a test in the afternoon. The conversion will go faster if you brush the pool then vacuum to waste daily if possible, filling as you go with fresh water. The more often you keep the chlorine up, the faster the conversion will go. Don't worry about any other readings till the water clears. Your ph may test high, this is because of the chlorine. You don't want to add any cya in it because then you have to have a higher chlorine shock leve, if you have cya make sure you are in shock levels according to the "best guess chart". Keep the filter running 24/7 - backwash and vacuum to waste, add more water. If you have a DE filter the more you change the DE the better the goop will filter out. If you have a cartrige then try to clean it as often as you can. If you have a sand filter backwash often - and when conversion is finished replace the sand. You will know when the conversion is finished when you hold fc overnight, the water is a nice clear blue, the pool looks like you want to swim in it Conversions take a lot of work, and a lot of patience - the more work you do the less patience you need Hope this helps.
