Ph Level for Calcium Reactor?

[tofubox]

Hi guys,

Need some urgent advice on my calcium reactor. I understand that rowalith melts at a certain ph level. Done some research, some say 6.3, some 6.7, some 6.5

Since im setting up my calcium reactor all over again, what ph should i be setting on my american pinpoint controller? It has high and low reading.

If i am targeting for my effluent ph to be 6.5 can i set high as 6.51 and low as 6.49?

Any bros there using american pinpoint ph controller for ur calcium reactors? What should my settings be for starters? Before i start tuning?

By the way, im using a Deltec PF509, with fixed paristaltic pump, Bubble rate at 1 bubble/ sec. Is this right?

Advice most appreciated!

Calibration n accuracy of the probe is a variable. For me, I always measure the water outlet dkh to see if it is over 40. If not, I will lower the controller cut off limit. Measurement is done when the ph is at the lower cutoff limit.

U also need to regularly measure the tank dkh to check if the reactor output is sufficient to meet your tank demand.

This is my practice, it works for me HTH
