Using Thrusters as wave makers in aquariums

Have any pictures of it in your tank? Curious what the guard looks like.

The mp4 above doesn't play for me.

Ceratinly curious to see how these work out long term. Would be a significant savings over other large pumps for large tanks.

Very clever. Looking forward to long-term feedback.

This is very interesting! I'd like to know how these hold up without leaching metals over time.

With your guard design, how do you prevent things from getting sucked through the back and chopped by the thruster blades? Would you surround this portion with a mesh or sponge? Is this only to prevent large fish from getting pulled through?

This is concern only if I run this at 80 % power, I have already asked my resource to add more support bars to make tighter and narrow so fishes won't get sucked in

Very cool project!!

here is the video link I found for t200

Nice vid, Ravi, and cool idea to adapt the bow thruster though I'd be mindful of putting aluminum components into the tank.

Using a marine grade thruster as a wavemaker is a very interesting idea! I didn't even know they existed

One of my main concerns here, as others have already mentioned, would be how it will behave on 24/7 continuous duty. Those marine drones, which it was designed for, are mostly battery operated and are used for a few hours only each run. I do not expect much issues with properly cooled (immersed in water) BLDC motors, and there seem to be no other moving parts that would wear with time, but I still would be cautious. Would like to see how it goes in a few months time.

My other concern would be heat. Based on the photo of your power supply, it draws 94 watts of power. This is close to having a 100W heater turned ON continuously, and is a significant heat. Did you see any temperature increase in the tank so far? What kind of cooling do you use? If we convert this heat into evaporation, very roughly, it will vaporize one gallon a day.

Wasn’t sure if this was a bow thruster or what kind. I see now a water scooter or drone thruster. Sounds good I’m following. Needs to be screened well cause anything sucked into it will get shredded! I’m sure there is not a stuck impeller default either.

AMAZING NEW PRODUCT!!!
instantly turn fish into fish food!!!

This is a printable 3d weed guard for the Blue robotics T100 and T200. never tried it but hope it helps.

that should be easy to do by using an amperage sensor and relays. But it is a good idea
