Low quality that is..
Now if you are going to go shrimp tank on the 40b, why bother with a sump? I am a true believer of sponge filters for shrimp tank. Anything else is just more work and not necessary.
because it's going to be a planted shrimp tank. and sponge filters are big and ugly. the sponge filters are for my soon to be breeding tanks
i'm thinking about breeding some kind of fish. maybe endler's, maybe guppies. if i could get the rainbows i had before, i would love to breed those. who knows, i may just end up culturing bubonic plague or something in those tanks. just for fun of course...LOL
