Jebao PP4s ordered, on the way here!

[Nano101]

Excited to see what these little guys can do. They will be replacing two Hydor 850s with a Hydor wavemaker. I have a light already set up in my cabinet that will be on a timer, so I can use the night mode without having to have the controllers outside my cabinet. I hate seeing equipment.

 

[Brad Bessett]

Hope you ordered seat belts for your corals!

 

[Nano101]

I figured if they can handle the two 850's, I can dial down the flow with the PP4s. I only use the powerheads for the back side of my tank, the front corals use flow accelerator nozzles. They get a gentle breeze. Hoping I can just hone in on the control part.

 

[Brad Bessett]

These are for a 12 gallon tank?

No Detritus on my sand bed! and right now at least no sand storms. Crystal clear water. Skimmer picks up anything suspended. Not even using a sock. Everything passes through chaeto, then my Remora S, then to the return chamber

Well I ran two PP-4's in my 45 gallon cube and had major sandstorms on the lowest setting. I ended up having to scramble to buy two 18W DC power supplies to drop the wattage and slow the pumps down (they come with 24W supplies). I can guarantee you are going to run into the same issues and probably worse if you are running a 12 gal.

Be prepared for some SERIOUS movement.

Like my 850s, I bounce the flow off the LR. Why would I get more flow with a PP4 than a hydor 850?

 

[Brad Bessett]

P.S. I run a SPS dominant reef and need the high flow and it was still waaaaayyyy too much.

I recently upgraded to a 90 gallon display and now run 2 PP-8's on the lowest setting and still have sand movement all the time.

Because the water deflectors and impellers are much different. You'll see soon enough

Hope I can control it. Worst case scenario is I'll use night mode on continuous settting

 

[reeferfoxx]

For a 12 gallon tank i would have ordered the Jebao SW2 nano powerhead.

 

[Brad Bessett]

Night mode on continuous defeats the purpose of getting them but yeah, that's an option. Just be ready to look for low wattage DC power supplies.

How would I convert the power to 12v (or whatever I need)? Can someone walk me through that?

 

[Nano101]

Soo, if too much blow, I could cut the wire to the power head and use this as a step down?

 

[Nano101]

Or can I just use a 12v power supply (with correct current) and connect it directly to the controller?

 

[reeferfoxx]

Jebao pp4's usually come with controllers. Why would you need a hydor wave maker?

 

[Nano101]

I currently have the two hydor 850s with a wavemaker. Changing out for the PP4s

 

[Brad Bessett]

No, you'd need to buy a lower wattage DC power supply (what plugs into the controller). You'll see what I'm talking about when they arrive.

I would put the wavemaker on ebay. If you've never used jebao powerheads, you'll soon learn
