Buildup of a 210 gallon Reef

[tgunn]

Penductors are positively NUTS.. I tried two in my 4' tank. With the pump (PCX-70) pushing water from the sump in the basement, the flow with the pump at full power was absolutely insane:

And I didn't even have them aimed at the surface; they were aimed across the tank.

The flow shot across the tank and rolled down the opposite side, causing the sand to get moved around qutie a bit.

That is exactly what I need with a 6' 30" high tank.

Thank you very much MickZu! I'm glad you enjoyed reading through it.

I'm not sure why but when I replied to your post I didn't see a picture before. Now that pic is showing up. Good Lord!!!

Welcome to RC MickZu !



Is that pic of Tyler's tank insane or what? That surface is totally boiling. I had two penductors at each end of my tank pointing toward the opposite ends, and it was really, really strong. If I didn't have a closed loop I would have set my tank up with penductors...

The flow was absolutely crazy. I think in a tank longer than 4' it would work out better because you could aim the penductor across the tank and the flow would have a chance to diffuse by then. With the 5000 GPH from my closed loop this was just too much.

The water was actually welling up and forming waves that would crash into the overflow quite loudly.

And that's just 2 eductors on a PCX-70 that's fighting the basement headloss too!

Good lord... Am I going to be able to keep sand with basically an iwaki 70 with two penductors?

Also, do you need to use small PVC from sump to pump and from pump to tank?

 

[MacnReef]

No need to change your PVC size...if anything make it larger. The Penductor puts a restriction on the pump, thats why you need a pressure pump.

Your sand is pretty established so it might not move at all.

The thing I found with the penductors is that the flow is in a very tight strong beam that disperses around 1/2 way across the tank to the point it won't really harm anything, so positioning was tricky when I tried them.

I ended up dialing back my return pump about 50% and leaving them running over night, each aimed across the tank and into the corner. I ended up still getting sand movement because of them though. That said, I think as with everthing it could be tweaked...

If I was running a barebottom system I'm probably have just aimed them down and bounced them off the glass to prevent the surface agitation I was having..

I just used the existing 2" plumbing that runs from my sump up to the tank and the existing 1 1/2" manifolds on each side of the canopy. No need to downsize the plumbing.

I'm still planning on taking another reefers suggestion which is to use one penductor and have the other nozzle essentially open but restricted to "balance" the flow between the penductor and open pipe end.

I'm sure you could tweak it to your setup, but beware that it's a helk of a lot more flow in a pretty concentrated beam.

Darn cool things those penductors!

You’re right rdmpe, I haven’t read your thread yet.
But I did click on your red house and all I’ve got to say is “awesome”

Well done!! :thumbsup:

I'm thinking about replacing my Panworld 50px-x return pump with a panworld 200ps with a pair of penductors. Anyone know a good deal about that type of setup?

Sorry im not much of an equipment guy but what are penductors and what are their purpose? I saw the picture with that crazy water movement is that from them?

 

[thrlride]

Hard for me to explain but the end result is huge flow from a much smaller pump than otherwise would be required.

That's not to say the pump is small, the pump I want is still 1700 gph pressure rated pump.

As thrlride said, it's basically a way to use a pressure rated pump to generate a LOT of flow.

You're basically using a pump that can push a lower amount of flow at a high pressure to get a lot of flow. So for example, a pump like a PCX-70 would be using around 300w of power (that's what mine uses) and it's 1500GPH flow was probably around 3000-4000 GPH after the penductors.

Contrast that to my Sequence 1000 closed loop pump; it can push a large amount of flow at a low pressure. I have it with open 1 1/2" nozzles and it pushes 5000 GPH and uses around 350w. So same amount of power and similar amount of flow, just a different way of generating it.

i just hung out with him last weekend, so i know he's still alive! :lol:

 

[thrlride]

LOL, I'm still kicking.

No updates on the tank really except that stuff is growing in quite slowly. I had a clownfish just disappear. Kinda sad considering I've had the chap for over three years.

Hey JR, did you get tickets to the October race yet? I snagged two near finish line tickets from work as a reward, wanna go?
