I just stopped by Jacks to see if they had anything left & the SEIO pumps are all on sale for $20 ea. I purchased two of the M2600's & two M1100's for each of my tanks. I wanted a pair of vortec M60's but I obviously couldn't pass up the $20 ea sale.
If anyone is interested in them they have the M640 & M840 or whatever their models are.
Has anyone used these in the past? I see they offer a flow timer & also a magnet to hold these vs the suction cups it presently uses. Wondering if I should order them somewhere or just stick with the pumps the way they come?
