I was wondering if anyone has run into lower pH issues when using something like all for reef or carbo calcium. I currently am having a lower pH issue (7.98 on my calibrated hand held pH tester) that I did not have before and I am not sure if it is related to switching to the DIY all for reef. I am concerned about carbo calcium producing bicarbonate and co2 and no carbonates, thereby lowering pH as well as making the production of calcium carbonate more costly to the corals. I am currently planning on getting a co2 scrubber to hook up to a nano skimmer in an attempt to solve this as I would rather not dump out my all for reef (which to my dissapointment has actually not been able to keep up with potassium and iodine (salifert kits) which had been stable when I dosed the red sea trace potassium and iodine (sparingly)+chaetogo+seachem reef builder+red sea calcium.
