I'm beginning to think that it might just be better to either dremel/remove baffles from the elos sump, or just use a different sump all together.
but FWIW, another elos mini owner on here was able to fit an Aqua euro 55 skimmer into her sump, (a crappy skimmer, but I hotrodded it with a sedra 2500 pump and meshed the impeller).
I believe she had to put the pump in the chamber with the return pump(same as the original)and take out the slanted baffle if im not mistaken.
the thing is, they dont sell that version of the aquaeuro 55 anymore...
they updated the design by direct injecting the pump into a bubble plate,
so it wont work, unless you find an older version of the skimmer, then change out the shyte resun pump that is worthless on it.
so hence my suggestion to just screw all that nonsense, find a plastic/acrylic/glass container to use as a sump, and then get a skimmer worth a damn, add a small fuge, attach a $30 media filter for GAC and GFO, and boom, your done.
it's just sad because the elos sump is really cool looking and works pretty decent except for the crappy skimmer.
and in their defense, they have at least come up with a plumbing piece you can attach to the ATO to clean out the skimmer injector every time the tank tops off with water. which is the main problem with that or just about any post pump venturi skimmer.
and that's my gripe, what business does one of the highest quality aquarium/filter manufacturers have making $600 dollar skimmers with stupidass venturi injectors??? not even a pinwheel eheim pump?? really??? for that price? WTF!
