Wet VS Dry Skimming

[Jessie55]

What is better i have been skimming more to the wet side as i was told it pulls more. The other day i added some kent marine trace elements and within an hour my skimmer foamed like crazy. Connecting one dot to another tells me that wet skimming could possibly be removing alot of good along with the bad. Or trace elements is crap....either way im going to dry skim for a while and see what happens.
