Help with pH

[jimbo222]

I'v had the same issue for the past year
7.7 ph with no ill effect's on my shrimp.
Finally last month i found a solution by running a quarter inch hose to the outside and attaching it to my skimmer intake. and now ph is at 8.2 , never seen it this high.
and for some reason my skimmer is pulling twice the amount of goo.
