ok yesterday added what was in the 20ppm range of bleach 4 times plus aearate the pool 24x7
Today as requested dug up history which which was way to attach a Excel sheet but here goes and hopefully some answers that will help you guys and gals solve the issue.
Date CYA PH FC TC Alk
7/09 7 6 6
8/8/09 151 7.1 1.3 1.3
8/22/09 125 7.1 0 0
8/23/09 125 7.3 0 0

So it appears my CYA was very high in 09 and I closed with 0 CC 0 FC .I would have closed around Labor Day .Not sure why it drop from 151- 125 but looked like had some issues that went to pool store two days in a row
Now for 2010
Date CYA PH FC TC Alk Hardness
5/14 55 7.1 0 4.2 203
5/16 56 7 0 9 197 Water was somewhat cloudy and thus went to pool place two days in row. Would have done normal start up with shock and algacide ,metal out plus phos out.Using 3 inch tabs tri chlor is side chlorinator. Did the recommended triple shock every three hours for one day or 6 bags of shock each time .Then left town as emergency in SC
5/25 110 6.5 0 0 186 Here is when added the murtaic acid
5/29 110 6.5 0 0 166 Started the Borax and Bleach between 5/25-5/29
5/30 70 6.7 0 0 191 Continued the bleach and borax
5/31 70 7.0 0 .5 210 Aerate,4 applications of 20 ppm bleach
6/1 78 7.0 0 0 210

Test kit OTO so can only measure TC .Ordered the K-2006 last night . Cannot do bucket test because no FC test kits

Reading threads it appears I had a issue with high CYA and TC-FC CC last fall at closing but when opening the CYA was at 55 .Thus as thread stated this means the CYA was converted??

So any thoughts on what to do other then wait for test kit? I will add Borax today for the PH

At the pool store 4 out or 5 people complaining about no chlorine readings.They are pushing Caribbean Blue product . wow

await a reply
