My tank has about 75 litres (about 20 US gallons / 16 Imperial gallons).
For a tank with Sewellia lineolata how much movement of water is best for them? Lowest to highest ranges approximate?
Just looking at external cannister filters to make my river tank (not a manifold design but something with the aquarium sealed at the back to create a directional flow) work better.
What does anyone reckon?
After some calculations, I found this is the speed the water has in a filtertube: An Eheim 2028 pro II, moving 1000 liters an hour through 18 mm tubes sees the water going through the tubes with this speed.
Clearly, this speed is not attaninable in a tank. Putting it in other words - the more the better
So, I'm worried about too much flow but also don't wish to be disappointed with too little flow.
Happy fish keeping!
