Hi,
I've been following the ABCs for a while now and my numbers are all within range as far as I can tell yet when I brush at times, I still see a small layer of green algae being peeled off of the walls. I SLAM my pool and brush it heavily and despite being within range, algae still seems to grow on the walls. It's not crazy bad. When I brush it, the water becomes a little murky, but after 2-4hrs of filter running, it typically comes back to clear without adding more chlorine, but it seems suspicious still.
I SLAM'ed my pool 2 weekends ago ( and just SLAM'ed it last night)
FC: 14 due to SLAMing (typically around 4-5 but can drop as low as 2-3 right before it gets additional chlorine during the day at 8pm)
pH: 7.4
CYA: 30
Alkalinity: 90
CH: 390
water temp: 77F
Uncovered
robot runs : every 1-2 days.
I tend to add 2ppm of liquid chlorine daily to maintain the right levels. I brush it every 2 days.
I somewhat regret having pebble tech in the pool as I feel like the little pebbles tend to harbor and hide some of the algae (ie: creates opportunities for it to hide on the walls). I wish we had gone the route of polishing the surface and making it nice and straight instead of roughed like it is now and wonder if that's not contributing to it at some level.
Any idea what could be going on here? I'd be happy to share the daily results (ie: right before chlorination) for the rest of the week if that helps paint a more accurate picture.
