Not at all, if you have surface film, try switching your filtration to a sump or a skimmer attachment for the aqua clear hob filters, this will skim the surface layer of water clearing it of foam and other detritus
If u decided to use a diy pvc u can check a vid on youtube how to make a fantastic one, this overflow can work with a diy wet dry filter IMO is the best filtration method for any tank
I would try adding some AC to whatever filtration / skimming method you implement. And using gloves.
