again a new starter

[Paul Vingerhoets]

Hello, mij name is paul living in the netherlands.
I own a zeeaquarium now it's about 200 l. Now. This one will be going away and there is a new one coming 180*70*65 cm. I also want to start with ATS

I do have 1 question iss it possible to make a upstream scrubber with only te water from bottum to top ?

I mean putting the drain from the disply down to the bottom of the sump with a slot in it en put the screen on top of it ? As if a waterfallscrubber wrong site up

I hope somewone understand what i mean. My englisch writing is bad i now.

Best regards
Paul Vingerhoets

Well yes I suppose you could do that, but if it is a submerged device like that you can just go with a standard upflow scrubber type design and not use the slot pipe. Just direct the overflow line into the chamber with the screen in it for water turnover

Welcome.

Yes you can do that, like this:

I don't think there are any bubbles koming out of the drain, the overflow will made out of 2 pipes 1 low en 1 high in the lowest there is a valve for silensing out.

but where are the air bubbles for ? to diliver co2

[Floyd R Turbo]

supposedly.

You can add a venturi for air. You will need to experiment first.

A better way is to let the overflow splash down into a growth compartment.
