How much flow is too much flow in a 20G Cube (AI Nero 3)

[RonnieSimmonz]

Hi All,

I am trying to dial in my flow / power head placement before I add some coral to the tank. I recently put an order in for a few hammer corals and a bunch of different zoas. I plan to keep SPS in the future once I’m ready to make the leap and would prefer to not have to change much at that time. Here are my AI Nero 3 settings. Any feedback?

Tank: JBJ AIO 20 Gallon cube with stock pump and flow head

Excuse the awful picture...but tank layout for reference

Could probably go higher on top end, like 60% and 30 on the down side, and turn it up to medium, more random. the corals will let you know

If your planning on SPS, you will want another nero3 if not 2 more.

3 Nero 3’s and my all in one pump for a 20 gallon? That seems a bit much don’t you think?

Nope, not at all actually. Otherwise I wouldn't have suggested it.

When I had a biocube(only 10G more water), I ran 2 mp10's on 80% reefcrest, and a jebao pp4 for SPS. It's not all about the amount of water the push, but how they push it, and where it's pushed too.

You want chaotic flow(more pumps firing at different times and different strengths), more then laminar flow(one pump pushing one direction).

You could probably do it with 1 pump while you have frags, but they will grow weird as they tend to grow into the flow. Also when your frags start to grow, they will block quite a bit of flow with only 1 pump.

In my 80 cube I currently run 2 mp10's, 2 jebao pp8's, a gyre, and a nero 3.

That’s insane! I guess I’ll be ordering another Nero 3.
