Right flow?

I have a 20 gallon dt and a 10 gallon sump. In the dt i have a koralia nano and a mag 5 from my sump providing flow. Is this enough flow or should i add another nano?

 

what are you keeping in the tank ? and plan on keeping in the tank?

 

I dont have anything in the tank yet im just starting the cycle. I plan on keeping zoanthids for sure and some other corals but not sure what yet. And fish obviously haha.

 

yeah depending on what you want to keep will be the flow you want. you could always add another k1 to the mix. on my tanks I never inclued the return flow probably because I always forget to add it. zoa and most softies do not need alot of flow but you can have the k1 hitting the tank and the nano hitting the surface.

 

I would also add at least a K1 pretty much regardless of what you're keeping, I would probably go up to 2 K1's or maybe even a K1 and a K2 if you are keeping SPS.

 

I believe that reef tanks should be about 40x-50x turnover. If you have a 20 gallon, I would suggest at least 800gph.
