Flow Question 18“ cube

[chipchipbro]

Hi guys

My tank doing fairly good but I am not sure if I run to low flow atm.

I do have the DC runner 1.2 pump which is 1200litres/hrs and also the tunze 6040 nanostream which can do 4500litres/hrs

Now, the tunze is on the left side flow direction to the surface and frontglass at maybe 30% power. The DC Runner output is on the right side (standard bullseye from red sea nano max) running full power.

Do I need to run the tunze 6040 with more power to get more flow?

Here a video of the tank and some corals.

I had a 18" cubed tank running the same powerhead. From the looks of the video I would not change a thing.
As it grows in you can up the power.
Nice system!

thanks mate! Sounds good to me.. i wasnt sure if I need more as the back of the tank is a bit quiet in terms of flow.
