Surface skimmer problem

[plant talk]

I use a surface skimmer as shown in the attached picture.But I encounter a problem.The light pipe sometimes has this repeat action, suck down and shoot up cause by the inlet suction of my cannister.This action create alot of air in my cannister and release a lot of bubble through the outlet of my carbon dioxide reactor.

Anyone who use this kind of surface skimmer had encounter this problem has got a solution?

Any better surface skimmer in the market?

The in-flow from the top is too strong. Reduce the inlet by turning the stick on top clockwise (or anti-clockwise can't remember ). This will stop the repeat action and stop the air flow into the filter. Think it will helps

turning it clock wise but not to much other wise all the water will be suck in from below. Just fine tune it until you got balance between top and bottom.

I have just did a tuning on the inlet and manage to stop the lightpipe from going under the water.But narrowing the path on the input, does it cause the cannister to work harder and shorten the lifespan of the cannister?There is also a loud whistering noise from the inlet pipe.

Could it be due the strong suction/ pump rate of your canister? I used to attached an Eheim 2028 and faced the same problem. I deduced that it may be due to the small inlet surface area of this type of skimmer.

You also need to adjust the amount of air trap under those white floating inlet. I use it with 1000l/h eheim2217 without problem

Thanks to all for the information, I will wait and tune till it is right.
