How do you stain the plaster of a swimming pool a blue-green color?

Answer 1

Do you want to stain the pool these colors? Or have you already done this thru lack of knowledge of swimming pool chemistry? If the latter, you have grossly added too much muriatic or dry acid to the pool. Unless your area has acidic water then you still have failed to correct the problem with chemicals made for that purpose. The pool has been in an acidic condition for some time in order to get these stains. The stains are a result of improper chemistry balance - pH and alkalinity. The stains are coming from the copper pipes in your system - if no copper pipes then the heater heat exchanger - it is copper. Adjust your pH to and maintain at 7.2 to 7.8. Adjust you alkalinity to and maintain at 80 to 120 ppm. You need a good four in one test kit to do this. Cheap test kits do not give you what you need in order to maintain water quality in your pool. You have a sizable investment in your pool - don't skimp - it will get you every time.

If you have caught the problem early enough it may give you no further headaches. Wait the approx. 5 to 8 years for when the water needs to be changed and then have the pool professionally cleaned but be sure to get someone you trust and get recommendations. See what work they have done before deciding on any one company.
