Recently, I calibrated my Hannah HI98103 meter. The meter is seems to be accurate according to the testing solutions, and gives a nice reading with a +- .1 reading.
I tested my tank in it came at a dangerously low 6.8, but, my alkalinity is at 11.2. My question is two fold
1. How did my pH get this low? Both the reading in the aquarium and the reading in a sealed gallon jug of unused 1.025 salt water are 6.8, but my RODI is a normal 8.2. Could the salt be a bad batch and should I get new salt? (Currently using a bucket of Reef Crystals)
2. How can I raise pH safely without raising my alkalinity if it's even possible?
