I assume I can get cyanuric acid from places like Home Depot, Lowes, Walmart, etc. What should I watch out for in buying cyanuric acid? Any other ingredients to avoid?
My Intex SWG uses a pair of copper electrodes to generate copper ions and Intex has a spec (0.1 - 0.2 ppm) on copper levels. I think I had to add some copper solution to get things started. Where is a good place to find that- pool store?
Oh yes! can I use last year's Taylor test kit chemicals?
