Sean - I have read closely Ben's "High pH" operating guidelines (http://www.poolsolutions.com/gd/hiphpool.html) (http://www.poolsolutions.com/gd/hiphpool.html).
He doesn't directly address SWG chlorination systems, but does say that sodium hypochlorite is an acceptable form of inorganic chlorine to shock. I take that as an implicit approval of high pH operation with a SWG.
The PoolPilot manual recites the familiar pH range of 7.2 to 7.8. What are your thoughts on running in the 7.8 to 8.2 range, assuming all the other levels are maintained as Ben's recipe prescribes? It looks like the only departure in recommendations is Ben shows 100-120 for Hardness; the PoolPilot specifies 200-400.
I have my new PoolPilot (Dig220/SC60) still sitting in the box awaiting the larger pool replumbing project, but I am close to putting it in. All of Ben's high pH recommendations look good to me, primarily because my water tends to a natural pH of 7.8-8.0 using Trichlor - so I expect even more upward pressure on pH when I go completely to the PoolPilot. Thanks for your input.
