Recirc mod question....

[adamatic]

On a recirc mod, what's the best set up - intake from the top and output to the bottom or vice versa?

 

[UCanDoIt]

vice versa

 

[adamatic]

Ok, but doesn't that mean that I'll be taking 'unfractionated' water from the bottom and mixing it with 'fractionated' water at the top? What's the underlying principle behind this?

I don't know. I have just started looking at recirulating skimmers.

 

[TexasPete]

I would think it would be best to take the water from th middle of the skimmer and have it come out at the bottom.

 

[TexasPete]

I have asked about this on another thread so I might get an answer there.

take from the bottom so that you suck in fewer bubbles.

You want to take in water from the bottom and inject it with the bubbles above that point. The idea is to pull in water and then mix it with air and inject it into the skimmer body. If you take in the water/air mixture instead of just water, you'd probably lose efficiency and possibly performance with the skimmer.

Just my thoughts. I've never seen a recirc skimmer set up other than drawing water in from the bottom and injecting it with the air higher than the point where it was taking in the water. So, if it were any better the other way around, I think we'd be seeing it done on the recirc skimmers being sold now.

This is not a technical response, but if you inject water with air at the bottom of the skimmer, then there's probably a greater chance of microbubbles spilling out into the sump too.
