Re: Cloudy pool/white stringy(snotty) stuff?
Hi, Star and welcome!
You have come to the right place and you have been given some TERRIBLE guidance.
1) throw away the calcium hardener and super clarifier. The first isn't for vinyl pools and the second rarely does any good.
2) put away the pH Minus and whatever you are using to shock the pool unless it's plain, unscented laundry bleach.
3) go out and get a simple drop test kit, called an OTO test kit from either a pool store or Walmarts or K-Mart. Try to find one that measures chlorine to 5 and Bromine to 10 (you won't use the bromine side) rather than the usual ones that go to 3 and 6. Measure your chlorine and pH levels with THIS and report it here. Forget the strips. They won't give you valid information. They seem easy but are VERY difficult to read correctly--half the time you can't anyway. IMHO, the BEST OTO kit is the Taylor K-1000. If there is a Leslies store buy their OTO kit, as it's probably the K-1000 rebadged with Leslies name on it.
4) Forget everything the pool store tells you about what the correct levels are.
5) Go to our sister site at PoolSolutions.com and take about an hour to read and absorb what's there. Pool care is actually simple, but you need good test information and a realization of what to do.
6) If you can drain and refill it might be easiest to start anew with a clean pool and fresh water, but, if not, I'm going to guess your pool is a 12' round with about 3' of water. That means it has 339 cubic feet or 2500 gallons.
7) If you can, take a water sample to the pool store to be tested but don't buy anything just yet, no matter how hard they push. First post the results here and we can advise you on what you need. Be careful: Pool stores make tons of money by scaring people, particularly novices, into buying stuff. Ten to one says they try to get you to buy phosphate removal. You don't need it.
For now, pour in 2 quarts of bleach after sunset and keep the pump running. Yeah, bleach. And post the the tests from the OTO kit. Test in the morning after adding the bleach, and be prepared to add two more quarts.
Once we get some numbers we'll either help you clean your water or, if you go the refill route, help you keep it clean with nothing more than bleach, borax, baking soda, your pH down, and ONE chemical from the pool store called Stabilizer.
