Hi All
I have a mini tank like the one below it's 15 litres including 2.5 litre sump at the back , It has a collection of shrimp and is largely overgrown.
It's been really useful for putting fry in.
Initially I started off with an airlift but it wasn't enough power to get the enough water through the filter media.
I then bought a 4.8w brushless DC pump thats USB powered , this fits in the 45mm x 45mm x 200mm space but is massively overpowered and noisey.
I've restricted it down a little with a mesh on the onlet, that I leave half blocked. but it doesn't fit the noise.
Has anyone tried running them off 3v rather than 5v?
Has anyone found anything that works?
Why can't manufactures declare noise levels, be great if there was a standard test. I have a bug bear about manufacturer that declare anything as Silent..
silent should be ZERO db it has moving parts so it's not silent..
