    You essentially have a fiberglass pool with the Fibertech having been applied. There is no need to add calcium in that situation.

    Actually, I thought the CH recommendations were similar to plaster for some reason? They are in Pool School ...

    Low CH is typically not an issue with anything other than plaster. High CH levels can result in scale developing in the pipes of a heat exchanger so you wouldn't want it too high.

    Fiberglass will experience cobalt leaching from the gelcoat at low CH levels. We don't really know how important that is, so we recommend CH around 220-320 for fiberglass pools.
