Greetings TFP'ers, hope all is well with everyone tonight.
Well good news bad news situation.
Good news is I finally convinced my father to go the BBB / Troublefree method...Bad news is his CYA is around 180 and his FC was only 2.0 and his pool is getting really cloudy (basically he got a new granular that is loaded with stabilizer and he uses the puck's so you know what that leads to)
Using chem's %'s from the CYA/Shock chart, for Regular shock it has 40% of CYA and for Mustard (which I think my Dad has ) it is 60% of CYA which puts a target Mustard shock right around 102 FC for his 19,900 gallon vinyl sports pool with a sand filter.
I did the CYA test and it was over 100, so got the pool store to just test that and they came up with 190, then I diluted 50% using spring water (they didn't have distilled) and came up with 90, took that and multiplied by 2 to get 180.
So we added A LOT today as his pool is cloudy and he is at his wit's end.
So there's the back story and my question is how high can the TFTestkits FC drop test, test up to? When I did the tests it would go from Red/Pink to just a very very light orangish brown and never get clear? So I even diluted it 50% with the spring water and by the time we got it up past 100 it started doing the same thing and I never seen this happen before.
I told him it would be best to drain but he didn't want to even after I told him once the shock process is done he would have to maintain a FC of 14 - 21 and that's just for regular and if he wanted to do the mustard min it would be higher.
Well sorry for the novel but appreciate the help as I just want to be able to get him straight and teach him what great things everyone taught me and I've only been doing this since April so still new at this myself but I'm still doing great.
I don't even know if its possible to maintain those high of levels or how long his shock process will take.
Thanks again and wishing everyone a troublefree pool.
