I'm a new to all this pool stuff.
I posted in Just Getting Starting, see geting-pool-chemistry-balanced-t65812.html
Test strips indicated off-the-scale CYA, I have drain approximately 50% of the water, CYA still very very high. On the recommendation of this forum I have purchased a Taylor K2006 test kit, and I have carried out the CYA test and I'm confused over the results.
I added 7ml of pool water, then added the correct CYA agent from the kit, to the 14ml line in the test bottle, shook it for 30secs, and then slowly added to test tube until the block dot disappeared, the dot disappeared very quickly, and the instructions tell you to read the number of the back of the tube, the thing is, the dot disappeared before it even reached the numbering on the back, does this mean it is really high...of the scale high?
I was wondering if the instructions meant the scale on the side of the tube, if so, that would be 1.8ppm.
