So.. it sounds like you have a few days before you leave.. if that is the case.. get some CYA for the size of your pool (again use the pool math app). You should be able to get it to into suspension in an hour or so. by putting it in a sock, letting it get mushy, and squeezing it out. Some people put the sock in their skimmer baskets. The water flow in the basket has the same basic effect as squeezing but slower and you don't have to monitor it... Then once in suspension it will take days to stabilize..
Under shoot the CYA .. that is target for 60. if you overshoot you will have to drain and refill to lower it.
Yes, based on Tenab's earlier feedback that was my plan to try to raise CYA before I leave. Great you think it is doable.
I think I'll go shopping on Monday morning for
- CYA to raise to 60
- Pucks & floater, not 100% I'll need them, but won't be too expensive to have as a backup.
When I get back tonight, I'll measure FC, CC, pH and assuming FC is >= 6 after running the SWG at 100% for since last night. I'll turn off the SWG and do an OCLT overnight, hopefully telling me if I have an algae problem to deal with, or "just" need to find a way to maintain FC for the 12 days I'm away.
I'll also try to find someone that can make FC measurements, adjust SWG production/pump run-time and add pucks if need be.
One question I still have, do I need to worry if FC goes too high while I'm away, or can I set the SWG production on the "high" side avoid it becoming too low ? This will be particularly relevant if I fail to find someone that can make FC measurements while we're away.
Thanks a lot for all the advice. I'll update the thread tomorrow once I have some data.
