I’ve been a long time supporter of Tunze products. I currently have their osmolator top-off device, 2 Tunze nanostream 6025s, and 2 Tunze streams 6065s. I recently had some problems w/ my Tunze 6000 controllable pump. Since this pump is discontinued, some parts are no longer available. I contacted Roger, the man behind Tunze USA, and he informed me to send it in. After looking at it, he said he could fix it for $25 or offer to sell me their current controllable pump, 6105, at a huge(did I say huge?) savings. I opted to get the new pump and received it yesterday.
The new pump is a major improvement from the old pump. The new brackets allow the pump to swivel in all directions; the old pumps would only allow left or right movement. The new pump uses a computer laptop looking power supply and the driver is built in; the old pump had separate driver and power supply. My old 6000 was rated for 1850gph, the 6105 is rated for 3,434 gph (don’t ask me how they figure these numbers out?). I can reduce or increase the overall power of this pump w/ the supplied 12v, 18v, and 24v jumpers. This pump is so much more versatile the the old one. I just hooked it up to my APEX controller and it’s controlling the Tunze to pulse from 30% to 100% power. Nice flow. Two thumbs up for Tunze!
