NO.17 Submersible Aquarium Internal Filter - Adjustable Fish Tank Filtration System

nick: This filter works great in my 35 gallon frameless cube tank. I purchased the 8w 200 gph size and it does not disappoint. Several things to know. First, it needs to be cleaned once a week for optimal performance. The pump is easy to take apart and put back together. It doesn’t take long and you can rinse it with aquarium water to preserve any good bacteria in the sponge filter media. Second, I have added some strips of biological filter material to the pre existing sponge filter material that came with it. You could add other types of filtration media like matrix balls or even replace the sponge filter that comes with it which is what I will ultimately do. Third, the adjustable flow switch works well. The 200 gph flow rate is when the switch is maxed out. I need about 175 gph for my tank so this works well and doesn’t bother my fish or plants. Fourth, you can run this pump submerged with the airline running from the nozzle to get oxygen and water surface agitation, or you can run it submerged without the air line hooked up and add an air stone to get oxygen and surface agitation. This is what I have set up and it is ultra quiet and the fish seem to like it. Plenty of oxygen,...

Karen C: Seems to be working really well so far. The jet of water is pretty strong even on low. This was for a 20gal water garden outside but the temps are too hot and my fish died. So it is now going into a 10gal aquarium and my betta will just travel between them when conditions are safe. Only problem I see is that I might have to custom make foam filter replacements..as I can't find replacements for when they start to fall apart. But I think it can be done from just blocks of filter foam. Also, there is no way to adjust the bubble stream..so I added a bubbler valve to it so I can adjust the bubble flow now.

CookieCookie: Update: I got this filter for Christmas and have used it for over three months now. It sounds the exact same as the first day I started it (really quiet).

My setup: 75 gallon fish tank that is stocked well (about 20-30 fish, I never know because some fish like to burrow and I don't see them for months but they always pop up alive and well out of nowhere). I use the 400GPH NO.17 filter and a piece of vinyl tubing from the filter into the back of a 75 gallon Marineland Penguin filter (that I don't use anymore) on the other side of the tank.

I have bought the Tetra Whisper and Marineland Penguin filters in the past for this 75-gallon (283-liter) tank. Both of my 70-gallon tetra whispers lasted 5-7 months before failing completely. My 75-gallon marineland penguin has lasted the entire year and a half I've used it, but it's become very noisy. Note, I clean my filters and the motors regularly - especially if they become too loud. I have a tiny 10-gallon tetra filter that has lasted 5+ years and counting, so I know how to maintain filters. But for my 75-gallon tank, I've used three different filters. From what I can tell so far, this one will last quite a while because of...

Cliente de Amazon: Me gusto bastante, filtra muy bien y mantiene muy limpia la casa de mis tortugas pero es muy difícil abrirlo para su limpieza, además la pieza del oxígeno por la misma presión del agua se desprende fácilmente. Sin embargo lo recomiendo ya que si mantiene limpio el tanque.

Jessica TrumpJessica Trump: If you currently own or have owned an aquatic turtle of some variety, then you know how filthy they can be. Aquatic turtles poop frequently and if you don't take preventative measures to keep their tank clean, such as using the proper filter, you'll find yourself with a very dirty tank. I own a red eared slider turtle in a 55 gallon aquarium. Over the years, I've had different filters. The top two things that have always irritated me when it comes to external filters is the constant sound of running water and the substantial amount of space they take up. More recently however, I came across NO.17's submersible internal filter. The overall concept is ingenious. This filter is completely silent. No more running water sound. And because this filter frees up space on the outside of the aquarium, it gives my tank a more modern appearance. What I also like about this filter is the adjustability. I can place the filter in any direction or in any depth that I like, even at the bottom of the tank where the gunk settles for quick removal. The suction from this filter is strong. The before and after photos are just five hours apart and you can see how the filter has completely cleared the...
