I guess in some aspects a continuation of the natural weir thread....call it plastic avoidance. is there any reason we could not make a natural "skimmer"? We dig out the location to place the skimmer already - why couldn't we just extend the liner similar to the natural water fall weir method into the cove, close up the opening a bit to say 10-12" weir, rock line it, use mesh w/ lava rock or?, fabric filtration and some other methods too if desired like bio balls, etc. A mesh or screen also could be inserted in front of the pump walling it off - somewhat a recreation of what Savio and some others do to semi-isolate the pump for removal, cleaning, etc. The filtration would be easy enough to yank and clean, an area could be made as large as one wanted to house filtration too as far as that goes. The cover can be simple as flat rock or even a regular skimmer cover if that trips ones trigger. Could the whole thing actually be as simple as this? My tiny brain makes me think it indeed is as simple as one wants it to be - and doing it this way I don't believe I would lose any filtration ability, rather maybe gain some? I know Mother nature has to do a great job of hiding her slimmers since I have never seen the plastic box yet Call me nutty for even thinking this if you want - but if I am I need to understand why too???!!! Has anyone done this or heard of it done?
