Best setup for micro / nano bubbles ?

[strawberrydreams]

If I had an aquaponic setup and just wanted to add the most amount of DO to my sump tank would a protein skimmer pump with the needle wheel put out more micro bubbles compared to a mag drive type pump with a Venturi attachment?

What pump or setup would achieve close to nano bubbles without have an actual nano bubble generator and gas fusion tank ?

Without knowing specifics it's hard to say. Which pump? And - is there any evidence that a pump can provide 'nano-bubbles' - definition unclear - and - since many people aren't concerned with this - I would say - it's a non-issue. However why are you wanting to add the most amount of DO to your sump tank - if thats the question - are you measuring DO? If not - there is no answer.

I don’t know which pump , that’s why I’m asking if anyone has experience observing which skimmer pumps might have more bubble output .

I was thinking of using a pump which can put out lots of bubbles utilizing a Venturi type system in the protein skimmer pumps in a moving bed filter to add lots of oxygen to the k1 media instead of using airstones.

It's unclear whether 'more bubble output' - which can be adjusted by the Venturi of most skimmers. Unless you're measuring DO - I'm not sure you can say - but good luck on your search

Thanks. Would you know how if there is much difference between a reef octopus pump and a bubble king , or other pump ?

Can AC pumps be fitted with the pin wheel type impeller found on skimmer DC pumps ? I’ve read that the pin wheels help chop up the sucked in air bubbles , but DC pumps don’t have very good head or back pressure.

I don't know. And I'm not sure there is a lot of good data anywhere except from the companies themselves as to those questions - or whether there would be any difference. My question to you was not a criticism of what you were asking - but - merely a wondering about 'why you're asking' - why are you focusing on Dissolved O2 levels with out any way to measure them. You could consider an oxydator?.

I’m going to set up external plants in an nft chamber that will also help to clean the fish water ( aquaponics ). More oxygen will help the plant roots, reduce pathogens , and help with the nitrifying cycle, and I’m not a fan of air stones. Will look at what an oxydator does. Thanks.

So you're talking about freshwater plants then ?

Yes.

I would consider something that can super generate O2 - there are numerous H2O2 based products out there

Aeration is up to 75% of the operating costs of wastewater treatment plants. They all use fine bubble aeration (air stones).

I’m only aware of h202 dosing pumps used in greenhouses. You can only add so much before it becomes unsafe for plant roots. Usually 10 ppm is a general baseline.

I agree, and think an air pump would be an easy solution , but they are so loud , or have an annoying hum that makes it uncomfortable to have a set up in a living areas.

Also thought that since I’m using a water pump for the filters maybe I can utilize that energy and get air bubbles using some sort of Venturi or “nano Venturi .”
