4 Year's Experience - Quick Update

Theiere's comments, I believe, are all correct - I certainly meant Sodium Bicarbonate for the TA!  As for CYA "lock" Theiere is correct - you do have to put more Chlorine in the pool - as we found out when choc'ing.........

There are other posts which reference a table to show how much Chlorine is needed at different CYA levels.   Chlorine / CYA Chart).

One other thought I did not mention - I believe it is essential to get a good pool testing kit.  I think without this I just would not have been able to get accurate figures for the Pool Chemical Readings and hence would be "flying blind".

I have both the PoolCool Cl/pH/TA and the Scuba+ Cl/pH/CYS and can recommend both.
