Help, I messed up. I opened the pool this weekend and it was pretty much a disaster, nasty and green and 2 foot low. My dilema is I've run out of the R-0871 reagent for testing FC levels. I reordered but it will be a few days until it gets here. I have an OTO kit but it only goes to 3 and I am trying to shock the pool. My last reading was 14 FC .5 CC so the 3 limit doesn't help. Is there a trick I can use to at least get a ball park to know if I'm in the shock level using the oto kit?
