Any specific brand/model you recommend? Nothing fancy though, only to move the water and agitate the surface.
Thanks
Thanks
Hydor ones work well and the magnet mounts are nice.
Thank you Becca, it looks good but the customer review stories about fish getting electrocuted are kinda scary 😆

This might be shocking to you (see what I did there), but many Amazon products are knockoffs. I actually avoid buying things like this on Amazon. If you want to be absolutely safe, there is a type of propeller pump that has the motor on the outside, but it WILL COST YOU (think hundreds). I can't remember what it's called.
FWIW, my hydors produce voltage, too, but it's induced voltage that results from a motor running in the tank. As I recently learned, this is different than actual current running through the water (amps) and is a given if you're running any sort of pump in a tank (askJLW about this one). I had problems finding an affordable tool for measuring amps that would work in an aquarium. I have "volts" coming from the hydor in my 55, but they're not anything that will harm the fish because it's not an actual electrical current. Same goes for my 33.
The other thing to keep in mind is that this is a much bigger issue for saltwater than for freshwater. Saltwater is more conductive and more corrosive than freshwater.
Just stick a block of poret foam to the intake. Makes it easy to clean.
I had or have an odyssea pump like that I bought a long time ago. As far as i can remember it worked pretty good. Still does I think. The light fixture on the other hand wasnt so good.
I have had great success with the Maxi-Jets in tropheus tanks. If you are are just looking for movement you can set them up in the circulation mode. Used the many times in
Tropheus tanks. Just remember, in circulation mode you don't need to go big. The smaller ones do just fine. On the seventy fives I would just use one 400 on each end of the tank and sometimes only one. You can get them from Chewys for about 9 bucks.
The only thing I can find on Chewy with that price is 2.5w fountain pond pumps lol
