What's the difference between a china brand skimmer to a more expensive euro/us made ones?
I've noticed that bubble magus don't have a valve to control air .. Which is easily solved ,that's what I did and it's skimming better compared to without an air valve .. Always skimming wet even at max water output.
That's the diff from an expensive skimmer to cheap ones rite an air valve? Or is there other factors like reliability? Well ,expensive pumps do breakdown.
