Had it running on my 135 Gallon - that would be about maximum size it can do. I was using an 1100 gph pump throttled back a little, but no pump included.

No pictures yet as I haven't cleaned it up. It is in good condition except for a break in the acrylic at the collection cup outlet port (for an external reservoir). I repaired it with some silicone, but it could use a better fix.
