Submersible Aquarium Internal Filter 12W, Adjustable Fish Tank Filter with 320 GPH Water Pump for 50-150 Gallon Fish Tank

3rd Update: I bought this back in December 2022. After 3 years, it has worked for me since without any issues. However, the flow finally started going down a little bit, noticeably after a power outage and it had to start back up again. But after opening it up, cleaning it out, (and for some reason, turning it onto its side instead of vertical for a few seconds) got it working back to normal. This filter (and my setup) has saved me a lot of money I would spend replacing other HOB filters because their motors fail relatively quickly. 2nd Update: I've had this filter for just over a year and it still has the same quietness as day one. It is going strong and I haven't had to replace it or clean a motor or anything, besides pull out a few bits of duckweed that somehow got stuck around the outside. The flow has stayed the same which is crazy to me. I haven't even needed to buy a second as a backup. FYI, I also took a bit of a risk with buying this filter because not many reviews were out at the time. Now it has a few hundred, over the course of about a year. If you like good value and quietness, and don't mind appearance if you're doing something similar to my setup, then this is the one to buy. 1st 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). Original Review: 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 how quiet it has stayed and how I haven't seen any reduction in flow. Things I like about this filter: - The value for money is SO GOOD. I got this at $23.99 and it is $22.99 at the time of this review (oh well, haha). This is compared to a 70-gallon Tetra Whisper at ~$35 and a 75-gallon Marineland Penguin at ~$50 (which I got it for less than $30 back in 2021). It has worked perfectly for my 75-gallon tank, albeit with my specific setup. But it is great value for a 75-gallon tank. - How quiet it is Disclaimer: I've only had this for three months now, but it is still so quiet that sometimes I don't even think it is on and I have to see if there is water flow (which there is a lot of). Keep in mind that mine is submerged about 6 inches beneath the water surface, 6 inches from the tank gravel, and it's up against glass. - Water flow Based on my experience, with a good setup (intake on one side of tank, output on other), and if you don't get a faulty one, this filter is good for up to 100 gallons or 380 liters, MAYBE more. I read the reviews on here before buying and I saw one that said they got the 400GPH filter and it wasn't enough for a 10-gallon? Maybe they got a faulty one, because mine is putting out about the same flow, if not more, as my 75-gallon marineland filter. My marineland would slow down flow over time until I cleaned it out, and it has wheel filters that would stop spinning altogether. This NO.17 filter, with a piece of vinyl tubing that goes into the back of the marineland, adds another step of filtration, AND it is at the opposite end of the tank so water circulation is 10 chef's kisses out of 10. Without the tubing, it'll produce decently high current in the tank. I don't want high current because my gouramis prefer low flow, so the tubing gives that added bonus. It might actually have more flow than the marineland because the filter wheels started spinning again. To clarify, I don't have the marineland running because the motor is too noisy. - Safety for fish I have some tiny fish in my 75-gallon, namely zebra + pearl danios and otocinclus catfish (you can see a small danio in one of the pictures). I haven't had any fish get stuck in the filter, and I don't see any spots where they even could get stuck. If I had shrimp, snails, baby fish, or nano fish, I would worry about them getting into this filter. My advice: If you are using this filter (or most filters) with smaller fish, shrimp, snails, etc., then buy a fine mesh filter bag (something like this: https://a.co/d/1LUrOT3) and cover the intake of the filter. I use one in my 10-gallon tank that covers the intake of a 10-gallon tetra whisper filter. I got my filter bag at petco, but they might be at petsmart too. If you're thinking of using tubing with this filter, take the tubing attachments (one is small, the other larger) and take them to a Home Depot or Lowe's and try out different tubing sizes until you find one that fits. I found the larger one is good for tubing with an inner diameter (ID) of 5/8 to 3/4 inches. In summary, this is a phenomenal filter for value, quietness, safety for my fish (not snails, shrimp, baby fish, etc.) and flow (works for my 75-gallon). I might order a second one as a backup.

Best filters. I have various sizes of this brand, have lasted years, easy to change filter media, out of the way streamlined design. Keeps the water clear for its small size. Fits in various positions. Great value.

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, good filtration, and no noise. I have had it for two months now and it seems to be a great purchase for the price.

I dont know why theres any bad reviews on this filter. I have a 40 gallon breeder tank which houses my full grown turtle. Turtles are very dirty. I've been using a waterfall filter for 10 years. Always having issues. From the tank needing cleaning constantly to the turtle ripping it off the wall. This filter is awesome. My turtle can move brick pavers in his tank, hes strong. He has not gotten this filter off the wall yet, and believe me hes been trying. So the suction cups work great. For the cleaning aspect, I have it half filled, 20 gallons. its keeping it crystal clear. I bought the 12 volt, alittle over kill for 20 gallons but I'm sick of cleaning it every week . And for the extra few bucks, why not? I have 2 other tanks, a 45 and a 250 gallon. I'm really thinking of buying more of these for those tanks. If you're debating on buying this, dont. The bad reviews are people obviously using it wrong. The power is very strong, so if you have been using a bad filter to begin w clean your tank first. That will obviously solve the problem of it swirling all the nasty stuff around and someone thinking its faulty making yr water dirty. Also people having issues w the suction cups, make sure yr glass is clean inside. Could be algae or slime not letting it stick as well. Common sense. Glad I bought this. It's going to save me alot of time! Thanks

I'm using this as a pre-filter to circulate water through an aquatic chiller for axolotls. It doesn't have a lot of head pressure so make sure you have the right size for your situation. I have 1 foot of vertical lift and even though this listing said it could handle almost 3 feet, I am quite certain it couldn't. There's also a slight issue with consistent quality. The first unit I purchased was VERY difficult to disassemble and remove the filter media with the exception of the very bottom cover, which had a broken tab and wouldn't stay on. This 2nd unit is intact and nothing is broken. It's much easier to disassemble but the very top cartridge (where the pre-filter attaches to the pump) fits loosely and will come loose over time, causing me to have to reach into the tank and snap it back together. Other than these things, I'm not sure there's anything else out there that can do the job I need, even at double the price. It does work and it keeps the tank clean although I am using it with a sponge on the outflow as well, to catch finer particles.

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.

Très bon filtreur temporaire. Difficile a nettoyé les éponge, mais reste que ces un très bon filtreurs d’ici à ce que je reçoive ma pièce manquante pour mon filtreur principal ! :)

Grande vibration qui a effrayé mes poissons, bruyants et très difficile à ouvrir pour nettoyer les éponges, plastiques de mauvaise qualité
