Welcome to the forum! We have all been in your place- learning how to keep a pool can be confusing, there is so much that goes on with the darned water! Once you get the basics of your pool down, it really is easy. You are on the right track. Ordering a good test kit is the best place to start, this way you are always testing in the same way so you know if anything changes. The best part is you don't have to count on someone else. Before putting anything else in your pool, you can test if the stain is mineral by getting some vtamine c tablets, putting them in a sock and crushing them. Put the sock on the stain an rub. If the stain lifts off it is mineral. If you crush up a chlorine tab, put it in a sock and do the same, if it lifts it is from organics. Once you identify the stain we can better advise you on how to get rid of it. Please post your results,
Thanks

Watermom, Chlor-Brite is 99% dichlor...
Yesterday registered no chlorine so put 1 ounce in. Today heavy downpours and again no chlorine so put in 1 1/2 ounces..The pool is looking even better though. We have no stains and the green tinge seems to be lessening. The tinge was ONLY when we look at the bottom.
Test kit should be here Wednesday, hopefully, Curious about ALL chlorine levels. Alll the heavy rains raised water level about 2 inches! Should I drain or let it dissipate?
Marie, Love the sock advise..Good to know natural ways of keeping pool cool!!! Thanks.
