Using the method above in my Geo 818, I was able to raise the pH in my reactor which in turn helps maintain a higher pH in the display. My tank is a 240 absolutely packed with SPS that grow like weeds. My min/Max CaRx pH is 6.9 and 6.95 respectively. My Alk is a rock solid 8.7. my skimmer is a SRO 5000 and runs 24/7. Display pH is 8.37 and runs a wonderfully consistent wave never dipping below about 8.1
hi ndrwater , you dont to anything to maintain your ph that hi with a carx? im thinking about putting one online but im worried my ph will drop form 8-8.1 to under 8.
