Super easy DIY nano tank w/scrubber

[Gapirri]

BUT what if my initial plan was to keep evaporation to a minimum ? (condition from SWMBO)
I guess that is easiest to do with a closed system, scrubber-top off-return pump in a closed tank with lid.
I dont plan to have a large amount of water in the sump, just the pumps and filtration stuff, perhaps even an extra pump to ensure the correct flow over the scrubber.

Please have a look again and comment.

Yes, that would keep the water from dropping and burning out the pump.

You still have a possible issue in that your sump has very little water in it.
But that is not really a requirement, especially with an ATS system.

How would one go about harvesting copepods from a scrubber such as this? would it work to have a sponge at the bottom of the sump to provide a living place for them. and then shake it out in the dt every few days?

No you don't want any sponges (or other mechanical filters) anywhere. You want the pods to just circulate around through the whole system so they can settle in the tank.

would the survive the trip through the pump?

cool idea,,just looks like the water level thing is the only hitch

[SantaMonica]

Baby copepods can make it through pumps. And copepods are the most abundant animals in the ocean.

this looks like the idea for me

I've been playing with much more complicated ideas for what is essentially a pretty basic thing lol

I'd nailed the idea of using a cascade from the display side over the mesh/screen but had been thinking of multiple chambers and lights coming down from the top!

Doh.

Cheers guys

How about you make the sump area very very narrow - perhaps a half cm - basically just enough for the screen. And put the return pump in the tank, connecting it to the sump. That way the sump could fill up entirely, yet the screen would get most of the flow.

EDIT:
I think I can answer my own question - algae will grow on the back glass if that back area is full of water....

It won't grow at all if it's under water.
