Sorry about the late response.. I was out there scrubbing till the wee hours, then I conked.
My CYA before va-ca was hovering from 0-40. My spa was completely draining into the pool every night the pool turned off. So my CYA was nearly depleted, because old sock just couldn't keep up. The repair guy came and replaced a Jandy activator with a Hayward one. RIGHT before we left last Wednesday I noticed there was a small air leak on the suction side somewhere, and the pump had a leak in the joint right after the unit. The spa continued to drain down anywhere from 4"-6". The check valve was replaced just last year. So thinking it was an O-ring in one of the valves, Mike ordered some... they came when we left. The trip was a "SURPRISE!!!! WE ARE LEAVING FOR SAN DIEGO in the MORNING!! (Which was really sweet... even tho I had a pool crisis on my hands.) So off we go. I asked my daughter & neighbor to come check the pool level every day at least... so it was being filled everyday. I left bags of store type shock out for them to throw in every day. They swam everyday.. but no shock was added.
Came home to black "dots on all the ledges and floor, green spots of algae all over. That's what I scrubbed off last night.
So I currently have RED, off the charts PH - Zero CL Zero CYA.
The first cya sock is empty.. so I'm thinking about running to Leslies and buying that quickie liquid stabilizer to get SOME CYA in the pool. I just added MA and Bleach. I'll take a reading in about 20 minutes to get a starting point.
I tried putting silicone around the base of the leaky pipe, waited 5 hours for it to dry (100+ degrees outside) - that didn't work. I took off the leaking activator to find the o-ring and replace it... but it was a different size, so I lubed it up and put the old one back in for now.
The pool guy is coming to fix the leaks after he orders the parts.. Below is the leak after the main pump.. and air bubbles in the check valve. Oh yeah, the booster pump is not coming on at all, hence no polaris.
If I can just get my water under control, at this point I'd be thrilled. I've decided to let the pump run 24 hours a day to keep the water level up.
