Recommendation for new pumps

bheron · 11/10/2020, 09:07 AM

Hi Roger,
As I mentioned in an earlier thread looking to replace my ol faithful 6080. Going to stick with the Tunze brand b/c of my great experience with the product and support here. Dont need anything over the top. Looking at the 6125 and the 6105. While I do have an Apex its looking like controllable (DC?) types might be more than I want to spend. Looks like the two I mentioned have some sort of control. I have a 220g medium stocked tank that the 6080s worked well for.

thoughts?

Thank you for the kind words.

6105 is controllable, 6125 is not. In general I prefer the controllable pumps for most flow situations as the ability to pulse and alternate is very useful for creating a more natural flow pattern. The 6085 is the current equivalent of the 6080. The main drawback to the DC pumps is that they won't last as long, the circuitry has a finite life span, which typically if well cared for is around 8 years, after that the capacitors will fail to hold a charge and the motor would need to be replaced.
