What is the recommended level of CH on vinyl pool, with Ti heat pump

[Scandela0629]

Morning to the pool gurus.

I have been reading all weekend, and looking for the current thoughts on the level of CH for a vinyl pool (SWG) using a Jandy Ti heat pump. The Jandy recommended level is 300 per owners manual.

My current level is 50.

In TFP pool school, I see the following:

"Is Calcium Level Important to Heaters?

Direct-fired gas heaters tend to build up a thin layer of calcium carbonate on their internal surfaces over time. This thin layer acts as a barrier to physical metal erosion (from high water flow rates) and chemical attack (from chlorine). However, this film is not indestructible, and it can come and go over time depending on CH and pH levels.

This does not apply to Heat Pumps, electric heaters, or solar heaters."

Does that mean I can "ignore" Jandy's recommendations? Or should I raise the level to the 200 or 300 level?

Thank you all!!

These is no chemical reason for needing CH in those devices.

That is up to you.

Jandy and other manufacturers tend to simply cut and paste the same generic water chemistry recommendations in all their products. They do not tailor them to a specific product need.
