I've read TFP site in the past but am now adapting to methods. I have just ordered a Taylor 2006 and waiting for it, but test results are from standard testing kit (not strips) I bought from local pool store.
I had some iron stains on my vinyl and steps that were effectively removed with an"clear result (Haviland)" stain and scale remover. I put in 3 quarts yesterday. This morning the water looked great. Added about 1/2 gallon of 12.5 liquid chlorine, and 8 oz of polyquat.
I backwashed the filter.
FC much higher than 3. ( best I can say with testing kit I have)
CYA best guess is about 140.
I've not done an alkalinity test for quite some time.
I then turned on the heater and after 3 hours the water is cloudy white. FC and ph are the same.
Could turning on the heater cause a reaction the turns the water cloudy?
Any suggestions are appreciated. Thanks for the help and for the forum.
