I currently have Aquachem 6-way test strips to test our pool water until we can get a better kit. All the information I have to go on is the color codes on the stick to the ones on the back of the bottle. There are numbers there but they are general numbers, yet I will list what the bottle says for that color if it helps. Aquachem has a website where you plug in the colors from your test strip and they recommend what and how much products you need to fix your water. But I know if the color shows pH low with a 6.8 above that color that I don't need pH down?! Because 7.2 is ideal. So these are the test results I can post....
CH (color code B) Low 100
TC (color code B) Ok 1
FC (color code B) Low OK 1
pH (color code A) Low 6.8
TA (color code B) Low-Very Low 40
CYA/Stabilizer (color code A) Very Low 0
Seeing as this is all I have, I plug it in the website by the color code listed on the back of the bottle matched to the test strip. The site says I will need 4.5lbs of Stabilizer, 20.0lbs of Alkalinity Increaser, pH needs adjustment with .5lbs of pH down, and CH is low add 6lbs of Calcium Hardness Increaser.
Does adding all that end up making the pH go up so that it would need pH down? I just find that strange. I am sorry I can't give you better test results, it's just what we currently have until we can order something better. Hopefully someone can help us out here. Also, we live in Tennessee, so it is terribly hot and humid here with PLENTY of sunshine on the pool the better part of the day. Maybe knowing that will help also. And we do know that we have soft water here. So I can understand calcium hardness increaser. Any advice would be appreciated.
