Sorry, I misread -- I thought you said you still had 1/2 tub. Don't buy them for that purpose. Decide how you want to go first. If you DO get trichlor, or dichlor, get the from Sams Club in "PoolBrand". That product line is one of the very few that's unblended . . . and it's VERY cheap.

I understand WHAT it means to dilute I'm just confused as to WHY you suggest it. Your method with dilution doesn't match the method described in the test kit so I'm wondering what is the purpose for testing a diluted sample for CYA as opposed to a standard unaltered sample straight from the pool?
Allows test of levels over 100 ppm.



I got the 23,000 gallon number off the Robelle site. Either I miscalculated or they have it wrong. Thanks for fixing it.
Nah. They didn't "miscalculate": they know what they are doing. "Bigger" sells -- so they all calculate volume at the 'spilling over the edges' level.


I'll keep testing of course but how long will it take approximately to bring the CYA level up using Trichlor tabs......month, two months, whole season?
Since you don't have trichlor (my bad) if you have access to Sams, get either their PoolBrand shock bags OR their 50# bucket -- both are cheap; both are unblended.
