I have a slight problem with the new Tunze Nano skimmer ... the top cover on the black box does not seat securely as it keeps popping up one end. It seems to me like the air tube is a bit too long & it pushes the cover up. Would it be OK to shorten the tube just a tad??? And the air adjustment screw is really tight! I can't seem to turn it by hand ... is it supposed to be like that??
