Filter 3 marina cubus 0.9gal
So... I maaaay have bought a bundle of 3 marina cubus "betta" tank (0.9gal each, 6" cubes, there won't be any betta in there, maybe a few neo shrimps) and now I'm wondering about filtration. If say, the 3 were set up side by side, could a single small canister filter (200l/h flow rate, for example) do the trick for all of them with a siphon tube between the 3 tanks ?
So the input would be in the first tank, that first tank would be linked to the second one by a u-shaped tube, then that second one would be linked to the 3rd one by another u-shaped tube, and in the 3rd one would be the output. Would that work, or is it a recipe for disaster ? I'm thinking that it would be a gain of space in the tanks, as well as less electrical sockets taken by tanks so small, and maybe more stability in the water parameters since it would basically equal a 2.5gallon, maybe slightly more if we add the water that's in the filter.
