Welcome to our forum.
I typically shock with dichlor but the other night I used MPS. My TC level was around .5 ppm before I shocked. I used the MPS that came with my HS starter kit. I believe it's buffered since they recommend using 3 TBS per 250 Gallons. My spa is 450 Gallons so I used 5 TBS. I also added 1 TBS of dichlor to get some sanitizing power. Anyway, tonight I checked my FC and it was around .5 ppm and my TC reading was 3 ppm. My water smells fine and believe the MPS did it's job. I've used MPS a few other times and had the same problem. I used a K-2005 Taylor test kit. Is it possible for MPS to give you a false TC reading?
Silly question guys from someone who hasn't even had his spa delivered (next week). Why shock with MPS rather than Dichlor? I understand MPS does not kill bacteria and some even use MPS AND Dichlor to shock. Any reason not to just use extra Dichlor?BTW I plan on using a silver cartridge (Monarch or Nature 2) as well.Thanks,Marc
And lastly.....gturn said "A clorine shock raises the Bromine level quickly, because it chemicaly converts to Bromine, when using clorine as your sanatizer it raises the Free Clorine levels."I think I'm misunderstanding something, because chlorine cannot turn into bromine.....isn't it that chlorine present with bromides helps somehow to convert the bromine to its sanitizing form?
