I have two (2) Tunze 6080 Streams powerhead pumps (2250 gph) with Suregrip Magnet holders.
$140 obo
$120 obo (works fine but the $15 propeller could be replaced if your fussy)
In operation for 2 years. Currently running on 120G sps system.
I don't have the original Tunze suction cup mounting assembly as I threw that away when I purchased the superior Algae Free Suregrip Magnets.
