I tested it in a bucket of water before putting it in my shrimp tank. There was a loud motor sound but filter went quiet and worked perfectly after a few seconds. -Modifications- I modified the filter for my shrimp's safety. The outside part is like a case, if you pull on the cord where it goes in the filter, the motor and where the impeller is will slip out. I covered the intake area (not the outer one) before inserting it back. I then cut a piece of filter sponge and put it in front of the spout (not right in front of it, as I don't want to interfere with the flow). Not shown in video as I forgot to record, but I also modified the filter media. I cut out the sponge part only from the filter cartridge provided, and I took out the carbon too. Only the plastic part of the cartridge is the one I used. I then cut a piece of extra fine water polishing pad, inserting it in front of that plastic part. Then cut a piece of filter sponge and inserted it in front of the polishing pad. This will do a good job on taking out even the finest particles in the water. -Filter review- Overall, I honestly love this small filter. It was bigger than I expected, but luckily it fit just right in my type of tank I'm using (has a top lid). Mine isn't really a tank though but a 3 gallon fish carrier. Not too much to comment on, as it works just as it should and it is actually really quiet. Although I don't know how quiet as my room already has water and bubbler noises going on. So it is super quiet to me. The filter has a top lid, which I liked. Helps with algae not forming on your filter media if you have lights right above the filter. Normally I don't like using internal filters, as it takes up space inside the tank, but I didn't have other options for my shrimp tank. Couldn't modify the top lid without damaging the lid that opens and closes. Hopefully the filter lasts long enough. I wanted a filter for my shrimp tank to lessen frequent water changes (water change encourages molting for shrimp, which is not good for them when done too often) and to clean up the debris so it won't be so difficult/take out too much water when partial water change day comes. -Other advice- Another thing I want to add is if your new filter is making a loud motor noise, it's highly likely because of the new impeller issue. Take out the impeller from the filter (it looks like a fan with a cylinder stone) and apply original Vaseline (unscented, 100% petroleum jelly) on the cylinder stone part. This will either lessen the sound (and go quietly eventually), or get rid of the motor sound completely. ... https://www.youtube.com/watch?v=9bPuhb0PNyY
