One of the best filters you can get for betta fish. Doesn't suck in shrimps too. Had no problem with it so far. The only problem is that filter media cartridges are one unit so every time you change it it has to start nitro cycle all over again, which i only noticed after 3 months of use that my nitrates are still very low to none. Because all nitrifying bacteria are removed every time i change the filter cartridge. That is the only bad thing i can say. Cartridges aren't washable. So you need to find other way of keeping good bacteria when changing. I cut small piece of old one and stick into the side of the filter but its too small, so need to find other way.

I required a filter for my 23ltr tank. Since using it I have found it work very well. It is a little fiddly changing the filters but not to any extend to prevent any one from purchasing a filter. The only problem I have with the Marina i25 is with the filters. They should last up to 3 weeks according to the instructions but mine are lasting only 2 weeks at most. They are luckily relatively inexpensive. I'm not sure if its due to my 2 goldfish being very dirty or the filters them selves not being designed very well. My tank suffers from brown slim but since purchasing the Marina i25 has been kept under control and the water is crystal clear.

I bought this filter for our 25-liter tank a year ago and am pleased with it. I needed a filter that could hang on a round fishbowl and had low-flow so as not to disturb our Betta Splendens. In leaving off the rear bracket and/or removing a suction cup or two you can give the water extra outlets and thus divide the flow even more. The filter itself is quiet but the plastic hood that rests on it does vibrate and multiply the sound.The only odd thing I have noticed is that it's output/flow is not consistent and seems to work better after I've cleaned it (I put in my own filtration media -- I do not buy the cartridges). Recently I've noticed a plant growing out of the bottom vents,

I use this filter on my betta tank and and does its job and it does it very well, my water is nice and clear and no smells. But the box states to replace your cartridge every 4 to 6 weeks, do NOT do this, a tank needs to cycle and by throwing it away, you are throwing away all the good bacteria and you will start once again with a uncycled tank and risk of high ammonia and nitrite killing your fish.

Great waters crystal clear for my angel fish, don't get why people say it's hard to assemble it's really common sense. Would recommend. Easy to clean out as the top separates from the bottom containing the sponge, to reduce noise move the pipe where the water comes out closer to the water

My fish tank water was murky before i put the filter in, but now its crystal clear and smells way better! It's easy to set up. All you've got to do is plug it in to the mains and watch the water become clear! My fish loves the little waterfall that it produces. I recommend it to anyone

I've been using this filter in a 19L nano tank for years now and it is great.However, do not use the cartridges. Not even once. Fill this filter with your own media instead, use small ceramic media and filter floss instead. Then replace the floss regularly.

Technically it's hard for me to comment on this as I've never been in the goldfish tank, but Gloria Rocket Boost, our fish, seems to love it! It also increased the time between us having to clean the tank from every fortnight to every 6 weeks! Bravo

A good decent versatile filter. small and discreet. Options to stick on tank wall or hang over lip. Not too loud and decent enough power for a small to medium tank (20 to 30 L). decent price and cheap filters as well. recommended.

I have two of these Marina i25 filters, one in each of my fish tanks. These are working great in my tanks with no trouble what so ever.The spare filter cartridges are easily available as well. Thank you to the seller and Amazon.

Great. It says 25l or 6.6gal and it works like a charm. It filters well and oxygenates it. I have a betta and 7 guppies and it is gentle but powerful. I really recommend for even a 5 gallon tank. I am very happy.

Bought this as a replacement as the motor burnt out on my last one. Kept with the same make/model as it had served me well for 4 years+. I find it easy to maintain/clean and find it works well in my tank.

This is my second of these filters due to how good they are hence the second purchase. Low maintenance, fairly quiet, (definitely better then most) all in all very happy.

Nice little filter for my 14litre fish tank. Does the job. Easy to clean wipe with a cloth. Also easy to slot in filter cartridge. Not too noisy either. Worth the money.
