Question for Ecotech Mobius Users

radiata · Tuesday at 4:21 PM

I picked up a Versa pump on BF for use as a dosing pump for a DIY nitrate filter. Can Mobius be programmed to pump 3 gallons an hour continuously? I'm asking because the Mobius app only gets two stars out of five in the Google App download site. I expected more from the app, especially from Ecotech.

it can definitely pump continuously, but i'm not sure about the rate. AI says it can do 3.1 gph, but i'm not sure about AI...

i think the biggest drawback with mobius is that the connection is only via bluetooth.

Agreed, it's hideous that I can't connect it directly to wifi

Thank you for the replies. Despite my second guesses, I might have to go with it. I can't find any continuous dosing pumps with a greater GPH, in the event my testing tells me that I have to increase the rate.

Do you have apex ? Can't you just use a pmpump? With a flow meter ?

Thanks for the suggestion, which could happen. Right now, I have an Apex PMUP running continuously with a restricting RODI tubing ball valve. I'm measuring the output of the filter to verify GPH flow, BUT I'm not that happy with the variability of my measurements.

I've never seen any nice things said about Apex's flow meters. I especially don't think they can measure a low GPH volume. Can you recommend any reasonably low rate flow meters?

what about a tom lifter pump? old tech i know. i have a nib never used you are welcome to have to give it a try. iirc they are around a gallon or two an hour.

FWIW ~~~ I just looked for water flow meters on Amazon (search there for "water flow meter gpm"). Most of those for sale are some sort of electronic, and unfortunately have metal parts. One like this might be suitable for my needs:

Your thoughts will be appreciated.

FWIW, I'm a (very) old Aqua-Lifter fan. When I first came across them many years back, I emailed CPR telling them that they could/should be used in their hang-on overflows to eliminate air collection. They then did. But, I never had a thank you from them...

Anyway, I have no idea if they can handle any back pressure, which I'd currently need. Thank you for the thought. If it worked and I needed more flow I could probably just add a second pump!
