I have a HOB skimmer and wonder if it's a good idea when topping off my tank or adding R/O to adjust the salinity by adding the R/O water via my skimmer vs. pouring directly into my tank.
I dont think it really matters. It will mix it up a little better, but it will mess up your skimmer production temporarily. I would just add it in front of a powerhead in the main tank.
