I'm installing a new proiein skimmer on my 55 gal. tank but not getting "sticky" bubbles. PH is 8.4 and salinity is @1.26? I havent checked carbonate hardness is this a factor?
I agree with others. I don't think water hardness matters. Also, if it's a new tank with nothing in it (ie no live rock curing, no fish being fed, etc.) you're not going to get any skimmate.
