I just ordered reagents from tftestkits. Does anyone know how long it usually takes for them to arrive? I've run dangerously low (I think it's dangerous on my R-0871 regent and I'm hoping I'll have enough to test the next two days).
If you dilute your water with distilled water by half your OTO can be read as double and it will help you maintain your chlorine levels until you get your refills. It's not as accurate but it will tide you over and give you peace of mind.
