2000 gph flow through 2 gallons of bio media.

OK would 2000 gph flow be more efficient than 600 gph. Though a bio ball chamber, in a sump?
If I use a submersible pump high flows are easy and use less watts.
Working on a internal filter for a 75 gallon. That will be heavily loaded.
Only concerned with ammonia, nitrification.
thanks.

Many many gallons of bio balls?
You are opening a can of worms with this question. Imo higher turn over rate for mechanical and lower turnover for biological.
If this is your own setup in the picture I would go for 600 gph or 1000 gph at most

Why the lesser flow?

Why the lesser flow?

I believe the reasoning would be that it would allow the bacteria to better obtain the nutrients, as it goes by them slowly; I have no idea if thats broscience or not though

Why the lesser flow?

It gives more time to allow for contact with bacteria. The bacteria have a better chance of pulling unwanted pollutants from the water.

 

[millerkid519]

Both of those answers are correct from my point of veiw. But if you increase the flow more bacteria will grow is the big question... because it will take more bacteria to process the water...

I am not sure myself, of what would be optimal.

I know in waste water treatment plants, the tank that nitrification takes place in is a violent air bubbling white water.

That's called a bio reactor. The idea is to get air on the media and help degass.
