it was nice meeting everyone today. Just a reminder, calibrate the refractometer with ro water and make sure it reads 0. I helped to calibrate two for 1st timers one was correct, another one was off by .001. We then tested it on my tank, I have it at 1.024. For those people using hydrometers u will have a shock to c how high the specific gravity is.
hey Ron, thanks for everything once again!
to tell you something funny, i was shocked to see how low the specific gravity was! (1.020)
