Sicce Shark Pro Nano 320 Internal 85 GPH Aquarium Power Filter up to 20 Gallon Aquariums | Quiet Spray Bar Mini Fish Turtle Pond Tank

ive had an over the back filter for as long as ive had these tanks. the monthly changing of the filters is a pain but you deal with it. my main problem is the NOISE. these tanks are in my bedroom so i cant have loud rattling noise, as the aqueon filter i had was doing. the tube part just sounded like hell sometimes, randomly. it just started vibrating against the filter and i had to futz with it to get it to stop. this is a lot of fun at 1am. and 4am. its fun to come home from working all day to hear it doing that, potentially for hours? annoying fish and cats alike. i decided to take a chance on an underwater filter. i wanted SILENCE. i wanted EASY. but ive never used this kind of filter before. i only have a 20 gallon tank (and a 10 gallon next to it) so i had to find one small enough to not turn my tank into a whirlpool. i got this 3 stage filter meant for my size tank. and within a day that water is crystal clear! its hard to see in the pics because of the reflections but holy heck. my water wasnt cloudy before but removing the old filter and fixing the tank up to cover the spaces needed for it kicked up sediment. it has a gentle woosh of water across the top, as i fixed it to the left side of the tank. i wish the instructions were a bit more detailed as it comes with extra parts i wasnt sure how to use. the box gave me more info than the instructions but obviously i figured it out. looks like it will be very easy to clean and replace these sponges, and far less work. i have one lab cichlid in that tank, one algae eater, and one snail. theyre all happy with it too. im considering getting a second filter for the other tank!also i cannot stress enough how silent this filter is. seriously you hear nothing. it installed in minutes. worth the money.

I bought this one and the smaller 250 versions for my fish room which doubles as my office. I have long been on a search for something that is quieter than HOB's, Sponge filters with air pump, etc. I saw a couple video reviews online and they mentioned these were quiet. I am not sure they did that justice. I have 5 of them running in my room and I can't hear these things at all. Sometimes I feel like I hear a faint hum, but seriously they are a miracle compared to the loud air pumps.These things move some serious water as well. For my smaller tanks I do have to put it on the lowest setting to reduce flow. I have heavily planted tanks so that helps, but I could see that it may not be the best for something like a beta in a sparse aquarium. This is the best purchase I have made for my aquariums so far and that isn't exaggerating.It's cool that you can choose whether to have an adjustable nozzle or a spray bar. I personally like the spray bars, but it is always good to have choices.The fact that they also offer a 5-year warranty is the icing on the cake. Nice job, Sicce.

The first filter I had in my 20 long didn't keep it clean enough and the water flow was weak. I put the 320 in and noticed a big difference in about 10 minutes. I put in the optional water bar and my fish luv the flow and it is clear and clean. Highly recommend easy to install and luv the magnet mounting makes it easy to adjust.

I really do love this filter. It is nice and compact and my tank is very clean just like my old over side filter. The only downside side is that it doesn’t filter as quickly as my over side filter if a dirt cloud is formed causing the tank to go a little darker in color. Never the less the water becomes clear just a little slower.

Great pump with adjustable speed but the filters are only supplemental. You'll need other filtration too

I replaced our filter that came with the tank when we bought it 8 months ago due to failure. This filter has amazed us so much quieter than the tetra whisper and the tank looks amazingly clear. You will not be disappointed with this.

They don't work.

Like the different attachments working good this is my second one for another aquarium
