hi
I am currently running matrix in an external canister, but was told it would work better in a push rather than pull config.
I was thinking of putting the matrix in a bubble magus mini80 instead , but the flow through a mini80 is 660l/h.
Would this change the filtration to non-aerobic ?
Would it work better to feed an airflow into the mini80 and have it aerobic ?

I think we run too much flow thru the matrix even if its sitting in the sump

I agree with this @2una! Matrix can and does remove nitrates but given how most sumps are set up, I think this ability is limited. Interesting thread on RC as well, would be good to try something like that.
 
So I moved the matrix from my external to a mini80 in the last compartment. Gives me space now to put in an auto tip up tank.

Sorry to ask a stupid Question.
Is it better to have low flow or higher.
In lumens terms what does each flow effect what.
I'm also running matrix in a reef octopus reactor. So I'd like to know low flow or higher flow
 
tank water passed through there should take at least an hour to fill a single liter to be effective.

what are you attempting to control/reduce?
 
My homie understanding is along these lines:
With higher flow = more available oxygen = aerobic - which is great to get from ammonia to nitrite to nitrate.

But to get rid of the Nitrate we need denitrification to happen (Nitrate to N gas which is what removes the Nitrate)
For that we need Anaerobic......that bacteria needs to have a lower oxygen supply so it then starts pulling apart the nitrate instead.

In theory those anaerobic bacteria can live on the inside of the matrix stones with probably the aerobic ones living on the outer part....the outer part ones help consume oxygen which in turn should help the inner ones ....
IN theory....but i don't think that works too well unless you get the stones in some slow a flow as possible.

Take the flow down too low then other problems start arising because there's too little oxygen.

Dube that reactor blanked off with a 1/4 jg fitting & a tap at the top might do the trick.I don't find those BM reactors are very adjustable

At this point it was purely to assist in filtration like LR.
That's why I ask the stupid Q what's are the different effects with high or low flow

Very simple answer (because it is more complicated than this) but low flow areas usually grow bacteria that remove nitrates and higher flow areas will produce bacteria that breakdown ammonia and nitrite (insofar as the nitrogen cycle is concerned).

That said, it is exactly as @zippy asks: What is it you are wanting to achieve/control?
 
then slow, you may have to play with it, but the controlled flow out of the reactor depending on your media in your reactor should be real slow

How slow, let's say 17ml a minute, roughly a liter and hour. Once again dependent on your reactor size and media.
