Missing pool guy

Postby esa1178 » Wed 09 Sep, 2009 19:41

My pool guy has gone missing. A such I have to stabilize the pool. If I give you all my pool test levels, can you help me select the right amount of chemicals needed to balance?

PH = 6.2

PPM FREE CHLORINE = 0

PPM TOTAL ALKALINITY = 40

STABILIZER = 0


I have a half dozen 3 inch chlorine tablets in a floating dispenser.
Thanks!

For future reference, use the Pool Calculator to determine what chems you need.

First, your PH and TA is far too low. Start with 130 oz by weight of washing soda.

Second, you have no chlorine so add about 1/2 gallon of bleach, unscented with no additives.

After about a 1/2 hour of circulation, retest and see where you need to go from there.

Use borax if you only need to raise PH.
Use washing soda (soda ash) to raise both PH and TA.
Use baking soda to raise mainly TA.

If you continue to use the pucks, they will eventually raise the CYA so I would just use more pucks right now to maintain the chlorine.
