Alkalinity stuck at 0...after 50 lbs. Alkalinity Increaser

[heyaim]

The alkalinity is stuck at 0. After putting in 25 lbs. of Alkalinity increaser it did not raise. Another 25 lbs. of Alkalinity increaser and still it's registering at 0. What could be causing the Alkalinity to lock up like this? This is only a 9000 gallon pool!

What are you using to test with? 50 lbs. would have raised your TA by 400ppm! YIKES!

I'm afraid Watermom is right; something is SERIOUSLY wrong either with what you are adding, or with the way you are testing.

Check the packages: if they say "sodium bicarbonate" or "sodium acid carbonate" or "sodium hydrogen carbonate" as the ingredient AND the material inside was a fine gritty white fast dissolving material . . . you added the right stuff.

If so, toss your kit!
