I replastered my pool with Sider Crete about 6 weeks ago and expected that as it is a cement based product, there would be a higher than usual acid demand for the first few weeks. This was certainly true and about 27L later it is still requiring more than I would have thought.
I am testing at least every second day, and find I need to add between 500ml and 1L of acid depending on the previous use (deck jets, SWCG) to get the pH back to 7.2-7.4, after it has crept up.
This may well be normal, it just seems a lot. What would be considered "normal" for a 6 week old plaster pool?
