A Must Have
I just received my EHEIM Skimmer last night and installed it right away. I have a Fluval Floral Planted Aquarium. It had a heavy oily with a lot of dust particles on the surface of the water. I am running the Fluval C2 filter and two Finnex Ray2 Planted+ lights and I was getting a lot of surface glare. As soon as I installed the EHEIM Skimmer within 10 actual minutes I had a crystal clear surface ALL of the surface oil and dust was gone. I have it running on the lowest setting and its working great. The EHEIM skimmer is a bit big for my 8 gallon tank but soon enough the plants will hide it.
I had to make a screen for the inlet part of the skimmer so that my shrimp would not get sucked in. This morning I found two of my shrimp hanging out on top of the skimmer inlet. They seem to like it there and I am not worried of them getting sucked into the skimmer. I used the screen I had to attach my Java Moss to the back of the tank.
I also added some more buoyancy to the inlet. With the screen it did not allow it to float as it was design to.
These modifications are not a big deal and easy to do.

Excellent and Easy to Use Surface Skimmer
By Mike S.
The EHEIM Skim 350 is an excellent surface skimmer for freshwater and saltwater set ups. This is an excellent addition if you are looking to eliminate the unsightly and problematic oily film on the surface of your water. The assembly is straightforward and very simple. The Skim 350 has four parts. The bottom part is the motor housing and you'll be able to see the propeller on top of it. The middle part attaches to it and this is where the water outlet is placed. Inside there is a small foam coarse filter. The top part attaches to the outlet housing and is hollow inside. It also houses the surface skimming part, which floats freely and will adjust to the water level. The color of the unit is gray even though it looks black in the photo. It will look dark gray until submerged in the water when it will look light gray. It won't matter to most people, but be aware of this if you're trying to match the color to blend in with the other equipment you already have.
SIZE AND DESIGN: The skimmer is about 6 inches high (intake tube extended almost completely) and about 2 inches deep and maybe 1.5 inch wide. The small size makes it less obstructive and easy to place in the tank, but requires more frequent maintenance because the surface area of the foam filter inside is also very small. Also, the outlet nozzle cannot be adjusted to direct the water flow.
EFFECTIVENESS: This skimmer works extremely well. It will clear up the surface of oil and debris within minutes. You can run it continually or on a timer, if needed. The power output can be adjusted to accommodate just about any size aquarium. Also, reducing the water output eliminates the bubbles formed by air being sucked into the water column when the water is drawn into the unit. WARNING: If you have small fish or juvenile fish, they may be sucked into the chamber when they swim to closely to the skimmer.
SOUND: The skimmer is completely silent when submerged.
EASE OF MAINTENANCE: This is the only downside of this model. Because of its compact size, the filter foam inside has to be regularly cleaned. In a heavily planted tank where bits of leaves and other debris are more common, the filter foam will need to be cleaned out at least twice a week.
Overall, this is an excellent skimmer and I highly recommend you buy it. It's worth every penny.

make sure there is no air under the floating head piece if you want to run the unit on higher speed.
By Amazon Customer
It is a perfect alternative to expensive and big protein skimmers if you are looking to keep your water surface clean to promote oxygen exchange. I am running my tank on canister filter that has no problem keeping water crystal clear, but unfortunately it does not clean oils from the water surface. EHEIM Skim 350 is very economical (only 5w) and cleans water surface very well.
If you are having problems with occasional microbubbles, it is because of air pockets getting sucked in. I was running it on minimal speed, since anything more would suck water so fast that I would get air with it and the unit would breathe out a pack of microbubbles. Problem was that water was not going in fast enough. I ended up submerging whole unit into the water, turning over the floating extractor piece under water so there is no air under the floating head so it doesnt float so high and more water gets in. After getting rid of air under the floating head, I assembled it under water and brought unit up to the water surface. No it is working perfectly. the extractor head still floats, just not as high so more water gets into the filter and there are no more microbubbles on higher throughput.
