We have lived in our new house for just over 1 year, and this is our first pool. approx 10K gallons in ground gunite with cartridge filter. We had our first massive rain fall in a short amount of time and the pool turned green within an hour or so. Clearly we were on the low end of chlorine...at last check it was in the normal "range". It tends to run on the higher side of ph.
What is the best approach to rectify? I have granular shock, which I can add, so far I've just added 3 tabs and turned the pump back on (it had timed off). It's a clear green, I can see the bottom, and it happened very quickly, so I can't imagine algea already being present? There certainly isn't any growth or anything in or on the pool surfaces...just really full of rain water and now a greenish tint. We'll be checking the levels here soon, but I thought I'd post first to see if I should just call our pool guy out to handle asap or do anything more ourselves until he can get here to minimize any further issues. Our pool guy comes once a month to support our cleaning and chemical work - we'd eventually like to do it all ourselves, but we felt better having a monthly "check in" to make sure we don't screw anything up right off the bat.
