Raypak protek shield replacement

[tiona24]

Has anyone figured out when these (protek shield) have to be replaced? And also what to expect as they degrade . I know it says in the manual to replace when it’s reduced by a certain amount of weight but I can’t find anywhere what the original weight might be. Also, I’ve only had the heater for a year (Raypak 406a) we watch the pool chemistry to ensure it’s in line, but is the attached image normal for one season of use?

When you say replace, do you mean emptied and put back on, or do I need to buy a new one and where? Mine is full of blue stuff, and I noticed that in week 2 after installation 2 years ago when my sister's hair turned blue. Every Pool guy has said it's normal, and not to empty it. (Not that I could if I wanted to, it was impossible to get off. I'll try the strap wrench).

Welcome to TFP.

It should be opened with a strap wrench and replaced. Read RayPak Heaters - Further Reading

Can anyone tell me if this is normal? I see on another thread to use a strap wrench to remove it, I'll try that. But when it says replace, does that mean just empty it? Or do I need to buy a new one? Have had the heater 2 years, and it's always had this blue stuff in it, and the pool guys say it's fine but nobody can explain it.
