Flow control & Surface agitation

[JayaMukherjee]

Hello,
New to Nano

I have a small 12 x 12 x 12 inches planted nano tank this has a Ehiem 150 Classic filter....


The flow is high and there seems to be too much turblance (video attached)
The plants uproot with turbulance as i have Fluval Plant and Shrimp Stratum which is light.
I want to have less flow so that my guppy and shrimps can stay well (this I achieved by clogging the outlet with a sponge) but surface aggitation reduces
is surface aggitation required even with canister filters

Please suggest how to have optimum agitation with less flow

You could put a bit more media in.
Also the media will slightly "polute / clog) so the output will get less slowly.
I'd like a flow.like this hahahha

It's full with media (ADA bio media) no space left

But it is quite new clean ?

Try covering inlet and outlet with sponge sheet...
Or you can attach the outlet to a top filter...
A box on on top of your filter which holds water and slowly releases it in your aquarium passing it with a cloth media...

Hi JayMukherjee,
You currently have a filter pushing 300 litres per hour in a 28 litre tank.

If the filter had no media it would be turning over ten times the volume of the tank per hour . Even with the media it’s still turning over a lot of water every minute.

To answer your question.
No you don’t need that much surface agitation. Yes a very small amount of movement on the surface is helpful with oxygen transfer but not that much.
Block the flow any way you can you will still have more than enough surface agitation.

Hi Experts,

This is what I have done to control the turbulance and have good surface agitation

Is this Surface agitation enough or something else to be done
Please suggest

Hi ,
While you are waiting for an expert I will add my comments if I may?

That looks like a good amount of surface agitation for almost any day of the year.

Only in the extreme heat of a very hot Australian summer heat wave would I consider an added extra air stone to be of any benefit.

As another non expert I agree.

As mentioned since this is a new pump, the outtput is high but will decrease over time.
Looking at the pics / vids, I do not see the outlet spray bar attachment. I would try the spray bar attachment, it may allow the output to be released across the entire area versus one spot. It still may be alot but then it was recommended to enlarge the holes in the spray bar.
By no means an expert, but... it worked for me.

Good Luck!

Well my advice is to get a smaller filter. A nano filter. A sponge filter driven by an air pump or a hob moving 160lph. But hey I’m no expert either . Or even better get a 40l tank .
