NICREW Slim Aquarium Filter, Quiet Fish Tank HOB Filters for up to 20L Aquariums, Adjustable Flow, 160 L/H, 3W

Fantastic little filter 10/10

I bought this filter for a small planted tank, and surprisingly it was amazing. It has a good compartment for the filter media so even if you don’t use the refill that the company sells you still can do a nice layout yourself to have your own set of filter media, the filter is easy to set and you can adjust the size of the pipes for the hight of the tank, not noisy at all, has a good water flow for it size of course, perfect for shrimp tanks and nano tanks were you don’t have lots of space. Strongly recommend for nano tanks and tanks with max volume of 10l

Running fine for 4 weeks then suddenly leaked a lot of water out of the blue. Too late to return, which is annoying.

Excellent very pleased perfect for my 15lt tank lovely gental sound of water

After less than 2 weeks use one a tiny shrimp tank it's pretty much giving up and the flow has almost halted completely!The filter isn't clogged it's the motor that has gone to a 1/4 its original flow rate somehow....You will be better off getting a sponge filter over this, they're cheaper, more efficient and effective and also provide aeration.Changed from 1 star to 3 because the seller gave me a refund on this and they didn't have too, this review is for the product 1* and the edit is for the kindness of the seller but the product is still 1 star in my eyes but maybe I got a dudd and for this price they can't be first class quality but you'd hope they'll last longer than 2 weeks either way.

Tiny hang on back filter but bigger than some filters. Frosted plastic makes it easy to inspect. Almost silent operation. Great price too.Comes with pre filter foam which most filters don't bother with which is crazy.Only downsides 1. it takes a plug socket. Would have preferred usb power. 2. The space for media is very limited but bigger than previous filter.

I am new to ' fish keeping '. Spent a small fortune on the learning curve. This filter has impressed me. Easy to set up and my goodness does it filter the water! I've had to clean this more than the other filters I've used because it removes more waste. It is only suitable for a nano tank as the only filter. I've used it in addition for a 30 ltr tank and by adding this it's kept the water cristal clear. I keep minnows so a strong filter is detrimental to the fish as they are not strong enough to swim away from the pull of the filter so by using a less powerful in tank filter and this nicrew waterfall filter, I have very happy fish and a healthy tank.

Worked great for 3 months but woke up this morning to carpet completely soaked from leak at bottom of housing ill try to attach pics. It took a quarter or my water out and soaked the tank wood base and is ruined I will now need a new base and I've spent 2 hours drying the carpet.If you wanted to get this product because it's cheap. I recommend you silicone the bottom. So that doesn't happen even if there's a manufacturer defect and I recommend you do not buy their inserts for the filter. You can simply buy some filter, floss or bulkk filter material and cut out to size and shove it in there. Using filter floss, this filter can work great as a polisher. Please just beware that due to its cheap manufacturing, it can be prone to leaking this is my overall impression inexperience
