Help me solve a problem.

Someone out there must know a way/the name of what I'm looking for.

Basically I want to pump water from a sump tank to a main tank without using a pump that has an impeller. For instance lets say I wanted to have guppies in the bottom but if they got pumped up to the top, not get shredded by an impeller.

I know this can be done via air. I'm going to look more into that. But is there an electrical pump that can achieve this somehow? Perhaps a venturi style thing as well?

I saw once and have yet to find it again but it was a pond pump that would pass debris through like leaves and such. I'm sure it would work for fish too.

You might want to look into jet pumps with aventuri style application. This could be done with propeller type pumps as well because the pumping of the water completely bi passes the main water sources.

I've only looked into this briefly. But here is a link of what I am talking about. The main water supply in this video could be recycled water from either the sump or main tank. You would need to screen off, and or use sponges to keep small fish out.

It would be simple to section off the sump with some foam = make a matten filter, and then use any pump you want. Fish would be protected.

The use I want to use this for is live brine shrimp and daphnia. I think it might be easier to circulate it between tanks than protect it from being sucked into a filter. With the matten filter though, you might be onto something because I could partition the tank very far away from the intake and that might do it, not sure yet though. An intake sponge on the pump itself turned down to a slight trickle was still too much, brine shrimp/daphnia were pinned to the intake.

Don't sump pumps for basements push out debris as well, meaning they wouldn't have an impeller system?

^ I believe those are jet pumps. I've never actually researched them so I don't know exactly how they work.

aqua lift vac pump??

I just found some jet pumps on kens and wondered if they would work too. Reminded me of the process of the jet motor on my dad's fishing boat. No propeller to get damaged on roots and trees and passes through the weeds, mosses and such without creating issues. hmmmm, oddly still fish related hehe

What if the tanks were level and you did a fish bridge then moved water back and forth (left tank to right tank then on a set interval move water from the right tank to the left) thus causing water to flow both directions through the fish bridge?

I have considered this as well. I can use a slightly higher tank and air lift it from the lower to the higher one. Jet pumps is definitely a direction I'm researching more.

I'm thinking that if you had enough filter area, then the water velocity across the filter would be very low, and then on the other side of the filter, you could use any pump you wanted.

You could section the tank using a wall of gray Matala mat with a layer of floss over it and have the pump on the other side away from the brine or fry. Massive area that flows to the pump, so massive reduction of suction on any small area... (planning this on our feeder farm to protect fry) Might need regular cleaning, but then it might be cheaper than alternatives.
