Reverse Tunze Nanostream 6040

shorediver · Feb 7, 2020

Hi,

Does anyone know if it's possible to have a Nanostream 6040 pump run in reverse? And if so, can that be done from its controller or via the 0-10V line?

I'd like to have my tank have a circulating flow in one direction for a few hours, then reverse it for a few hours, to get something like a simulation of tidal flow going. I realize I'll have to have an programmable controller for this like an Apex or Profilux, but for now I just want the future-proofing.

If not the Tunze pump, what would you suggest? I'd like to avoid buying two pumps if possible. This is for a 40b tank. I already have one Jebao RW4 but that can find a home in the saltwater storage bucket if it won't contribute.

Thanks!

The only pumps I know that can run in reverse in the manner you have described are the Rio Polario and Maxpect Gyres The Tunze cannot pump in reverse.

Thanks. And I think the Gyres can only do so with an additional kit right? I don't really want a Gyre because of maintenance headache, but if an out-of-the-box Gyre can do backwards flow in a single pump that might change my mind.

Will have a look at the Rio too. Appreciate that info.
