Water Chemistry help - very High CYA
« on: April 01, 2008, 12:18:59 pm »
I made an earlier post about my spa's apparently high chlorine demand.  I took the forum's advice and purchased a Taylor K-2005 kit.  From what I can tell, my Ph is quite low (6.8-7.0) and my CYA is off the charts high.  This is likely due to ineffectiveness of my chlorine based on historically low Ph (apparently i don't do well with test strips...)

Is a drain and refill the best option at this point (it has been over 4 months on this initial fill)?  

Also, what are the potential consequences of a very high CYA level?  Could there be any long term damage to the tub?

Any help is very much appreciated.

Thanks,
Russ

Russ,

Do drain and refill...4 months is enough even with perfect water.  I wouldn't worry about the CYA doing any longterm damage.  Thank goodness you got the Taylor...well worth the money especially considering how excellent the booklet is... 8-)

The booklet is great.  So on a drain and refill, what is the recommended cleaning procedure?

Just did mine last Sunday:
1.  Drained and refilled
2.  Opened equipment bay including controller cabinet and did a visual inspection.
3.  Wiped down waterline with a Tub Rub
4.  Applied 303 to pillows
5.  Applied 303 to cover, all sides
6.  Added 3 tsp. dichlor
7.  Jumped in after temp hit 100...aaaahhhhh....
Started around noon, finished process about 3 or so, including beer breaks, and was soaking at sunset with a martini!
 8-)

Thanks for the step by step, sounds too easy!  I'm in Massachusetts, so here's hoping it's relatively warm this weekend...
