Ive read many posts from fellow reefers and Randy himself that I shouldn't worry about my water PH being high coming from the RODI unit. But I want to see if I can specifically get an answer to my problem
The water that is made from my RODI unit is 8.8-8.7. I usually make 30gals at a time, it reads 0 tds. I change out my filters and membrane every 3 months which some might say is an overkill but ill take peace of mind anytime. Now when I mix the water with Fritz salt to 1.026 salinity, alk is 8.0-8.5 depending on the batch, but my PH than reads 8.6 to 8.7.
Now 24hours later, I add this water to my tank, which is a mixed LPS/SPS/Softie tank that I dos with BRS calcium, alk, and magnesium. I have this controlled over my apex, and my PH CONSISTENTLY in my reef tank is 8.67-8.77 within a 24hour period. When I have my refuge light it drops down to 8.67, during the brightest time of the day my PH is 8.77. ALK is consistent 8.4, calcium 440, and magnesium I barely measure but I don't think these have anything to do with PH levels, besides alk. Nitrates range from 10-20ppm, and phosphate according to hanna is .02-.03 if anyone is wondering.
My question is, ive been able to keep my PH pretty consistent, should I even worry about lowering my PH? Ive dosed vinegar before,30mls a day, which is nothing for 150gals of water volume, only to bring PH down, but only to see it go up again an hour or two later. What other solutions are there so I can lower my PH from my rodi unit so I can overall lower my PH in my reef tank to 8.0.
