Non-Optimal Water Level for 9010

[pjf]

I am using a 6080.50 magnet to hold the 9010 skimmer's neck at the same level as the rim of my sump tank. The skimmer cannot be lowered any farther otherwise the collection cup will hit the rim of the tank.

Unfortunately, the water level is at least an inch below the blue guideline on the skimmer. How much does this impact the skimmer's performance?

According to my experience, there is little difference.

As long as the skimmer is submerged at least 9.4" it should work but the air flow may have to be increased to compensate.

BTW, why not use the sump kit and then the water level will be inconsequential as long as it is below 11" and above 4"

Is your Tunze configured as a main tank skimmer or as a sump skimmer?

I’m going to need some guidance as to whether the sump-configuration or the aquarium-configuration is the best for my setup. The manual states that sump-configured skimmers must be placed in "quiet" water. But my sump is very turbulent with a ~800 gph air-water flow. In the picture, it will be held by a magnet on the upper left portion of my sump which is now occupied by a Remora Maxi-Jet pump. The Tunze's blue-line will be about an inch above the water level.

I’m having an acrylic sump cover shaped around the skimmer to control the salt spray. Since there is no mention of placing an aquarium-configured skimmer in “quiet” water, I assumed that this was the preferred configuration for turbulent water.

If the sump-configuration is more appropriate, do I need to install the output pipe with the foam cartridge? It will be useless for catching micro bubbles in my turbulent sump. Unless it is needed, I prefer not to install it.

Thanks for your help!

You cannot use the sump configuration with a magnet holder, it needs to rest on the included base to work properly. I would probably use the tank configuration.

i have a related question:
my skimmer chamber is about 14-15" full of water in my sump. should i create a pvc + eggcrate base to raise it up? I'm guessing up to the little water line?

i have a 9010

If you are trying to use it in the in sump mode then yes, otherwise I would just suspend it from the edge of the sump with the brackets.

I'd like to experiment with the in-sump configuration. What is the difference between suspending the skimmer with a bracket versus suspending it with a magnet? (Must the skimmer rest on a base when in this configuration?)

The skimmer has to rest on it's base when used in sump. You need to use the solid base plate.

Here's what I want to do:

1. Insert the solid base plate
2. Suspend with a magnet
3. Leave off the angle pipe with foam

Will that work? Thanks!

 

[Kinetic]

have you thought about just raising the skimmer with a platform made of pvc and eggcrate or similar?

 

[rvitko]

I don't think that will work, the problem is that you need to use the pipe and to reinforce the base plate and prevent water leaking out it needs to rest on a solid surface.

i have the 9010 and i have tried to supend it while it was set up for a sump, and no it didnt work. You need to weight of the skimmer pressing down on the bottom plate to make a good seal.

My Tunze 9010 must be installed with its neck against the rim of the sump. The blue line is 1-inch above the surface of the water. I have listed 4 options to remedy this. How would you rank these options in skimming effectiveness?

A. In-Tank Mode with:
• The blue line 1-inch above the surface
• The adjustment valve opened to allow more air
• Skimmer held by a magnet

B. In-Sump Mode with:
• The blue line 1-inch above the surface
• Skimmer resting on a platform

C. In-Tank Mode with:
• Baffle modification to raise water level to blue line
• Skimmer held by a magnet.

D. In-Sump Mode with:
• Baffle modification to raise water level to blue line
• Skimmer resting on a platform

Thanks!

as far as I know, if you use the sump configuration then the blue line doesnt matter...as long as it below the output pipe. But it does have to be resting on its feet for in sump mode.

 

[pjf]

So how would you rank the 4 options?

i have only run it in sump mode. The two sump modes should be the same since water level should not matter.

Roger,

My Tunze 9010 is held by a magnet with its neck against the rim of the sump tank. It cannot be raised or lowered. The blue line is 1-inch above the surface of the water. I have listed 3 options to remedy this. How would you rank these options in skimming effectiveness?

A. Leave things the way they are:
• In-Tank Mode
• Blue line 1-inch above the surface
• Air valve adjusted to allow more air
• Skimmer held by a magnet

B. Build a platform for the skimmer to rest on:
• In-Sump Mode
• Blue line 1-inch above the surface
• No magnet

C. Modify baffles to raise water level:
• In-Tank Mode
• Blue line matches water level
• Skimmer held by a magnet.

Thanks!

I would choose B as the skimmer is slightly stronger when use in in sump mode. When used in tank a portion of the water is recirculated where as in sump the skimmer is a 100% flow through design.
