last time using beckett skimmer,the tuning part is damn lazy.. haha
after changing to deltec, just need to on it and after setting ONCE to wet or dry skim, it will always stay at the level.
seeing so much skim mate after 1-2 days and cleaning it often makes me feel that it's pumping hard, compare to weipro, which will take quite long to have the skim mate i had for deltec for 1-2 days.
in any case, the end user who uses weipro is happy, and the fishes in the tank are happy, wei pro will be a good skimmer, it all depends on individual and budget
