There are 2 problems with a HiC2 pool:
1. Testing pH requires an additional step (dilution with *distilled* water) OR use of a pH meter.
2. Killing algae is a trick, because if algae grows, it can take 30+ ppm to get rid of it.

#1 is not a real problem; #2 can be, if you get mustard algae and end up with 55 ppm of chlorine, it will take weeks for it to drop, and will be hard on swimwear that whole time.
Well, I think for now I'm going to try the HiC2 pool. I'm going to cross my fingers that I don't have to deal with algae.

Are the instructions for testing pH by dilution with *distilled* water around?

Does this mean the 7.8 reading I have is not valid?
