I'm starting to get parts together for a Stenner install. I decided to go with a fixed 45MPHP, either the 3gpd or 10gpd...Assuming I add 1-2 qts/day, I'd run for 2-4 hrs for the 3gpd and 36-72 mins for the 10gpd. I'm assuming I'll be fine with the 10, but how fast can I safely add bleach to the system (just after the filter)?
