excellent explanation on the air draw matching the skimmer - running a skimmer with the air intake almost closed makes for an inefficient unit.
body and bubble plate of the vertex alpha cone 170/atb 1050 v2 skimmer - doesnt need to be built like a tank. I dont know why everyone needs a skimmer that can withstand being run over by a trunk. Its sits in your sump and doesnt exactly move around. Maybe go with a better quality collection cup if you drop it while cleaning it you dont shatter it. Replacement cups should be available and cost effective. Larger cup would be nicer than a small one.
sicce 1000 pump over the aquabee unless you can get the aquabee replacements for under $120.
external pump over pump under body design (I find the pump under bodies always end up being to tall or are a crap skimmer cause the body isnt big enough.
most sumps are only 12" wide - make sure the foot print has atleast one side that is under 12"
adaptor for pump intake to attach bio pellet reactor effluent - cheap
honest ratings capability
easy to disassemble and clean.
solid set of english instructions available online.
