Question

[Gastonreef]

I have a 34 gal rimless tank I'm starting to cycle but I keep having the sand move around making a bare spot. I know it's has to do with the powerhead but I don't know where to put the powerhead at to keep this from happening?

Put up a pic, maybe we can help.
Hey and welcome to R2R!

Powerheads in my experience start out pretty strong and will even out. you can use a sponge of floss or Plastic canvas to cover them till it breaks in.

Welcome to R2R! You could point it to the surface to break the stream up a little. That could help or a smaller powerhead.

 

[Joey waid]

That's what wanted to say. Point it upward. You could get a smaller one that does not move as much water too..

 

[Gastonreef]

I'll try that out

 

[Gastonreef]

Here the bare spot

 

[saltyfilmfolks]

Here the bare spot

Ah come on, we wanna see the whole tank:D
we like tanks.

and well be able to give you a little better advice on placement.

what size return pump do you have.

 

[Gastonreef]

ehime 1260 return pump and a rw8 powerhead

 

[Joey waid]

I would say that's a huge power head.

 

[Gastonreef]

I have it on low

RW 8 is too much for that size tank. You can try and salvage it though by using intermittent pulse. Switch to W1, speed 1 light, and turn the dial to about 11 o'clock.

 

[reeferfoxx]

Oh and point the the pump toward the water surface.

 

[Gastonreef]

Will do and will instill have good flow

 

[reeferfoxx]

Just try and play with the dial. Between 7 and 12 o'clock are the best settings for wave action.

yup. everything reeferfoxx said.
If you aim it up and back, so its has a lot of water in front of the head it will slow the flow(it working harder to push more water.. also if its pushing against the return flow it will create turbulence(and thats really good) and it will slow the flow from the PH even further.

 

[Gastonreef]

So take the powerhead and aim it at the return lines

Point the powerhead up and towards the back part, aiming at the overflow.

 

[saltyfilmfolks]

itll take some trial and error. And once you set it, ler it run for a while too.
IME sometimes I look over at the 55 and stuff has stopped waving. Then 15 min later it starts again.
Its a pretty fluid process.

 

[Gastonreef]

This is the settings I have it at now

If it works for you and isn't throwing sand everywhere, go for it. Otherwise, you'll have to wait for coral to determine correct flow.
