I am getting a lot of small what appear to be copper flakes coming out of my heater and then into the pool. I figured this may be my heat exchanger going bad so I bought a new one and installed it. Same problem still. Any ideas?
Heater is a Sta-Rite max-e-therm 400,000 btu
ph level is kept a 7.70 via autopilot total control system.[attachment=0:2jaqo392]copper flakes.jpg[/attachment:2jaqo392]
