I haven't needed to SLAM the pool for 17 years. Last week we experienced a "significant weather event" and the pool finished up with a belly full of mud.
And it was the day before the Easter break and we were going away for a week. Oh well - just turn it off and deal with it when I get back.
Yes, it was a lovely shade of green.
Didn't bother testing the FC - had to be 0 so just tested the CYA which was around 30 so I added 13l of liquid Cl. (It's labelled as 125g/l which I believe corresponds to 12.5% on the Calculator here but it acts more like 6% so I just leave the calculator to 6%). Should have raised the FC to around 15. Tested it an hour later and it read as 16 so looking good.
However, oops, that was the last of the r-0870. Normally, I like to stay ahead of the game but slipped up this time. Of all the times to run out of reagent!
Hmmm... there's that old bottle of r-0870 which I put aside when I got the new bottle last year. As expected, it had gone pretty hard. Nothing to lose so let's just "scrape" some off and try it. Turned the water a nice pink colour and read as 17. Don't quite know what to think of that. But the new reagents won't arrive for a few days. Time for some creative water treatment.
After 3 hours it had dropped to 12 so added 3l of Cl and it tested back up to 16. All I can do is brush and brush and add a couple of litres every couple of hours and see what happens.
This morning, it's a pleasant shade of cloudy blue so something's going right. FC dropped to 12 overnight. It's a cartridge filter so I'll just clean it once a day. The infloor vents are keeping the floor agitated nicely and saves me the bother of vacuuming at least.
I'll just keep doing this until the new reagents arrive. I'm guessing the water is going to be clear before this happens so I don't know whether to trust my dodgey reagent or just gradually back off the amount of added Cl after it clears. Any suggestions welcome.
Thanks,
Paul.
