I have a new spa for about a month with the in line spa frog system. I have went crazy trying to get this correct. Finally after 4 weeks and the bromine cart is still full I realize I have no water flow through the frog. I took cap and carts out and turned pump on. Nothing. Finally took inlet hose off and turned pump on. Had flow. Hooked everything back up and now I have flow through frog, must been air locked.. So back to my question. After a complete drain and refill. I had a calcuim level at 100. I was going to set it to 200. Calculator said 4.6 ounces of calcium. For 310 gallons.
Now I cannot get a red tint when checking calcium. Taylor 2005 kit. I can check tap water and it's about 100. I'm taking a sample to store today. Any ideas? Thanks tony
