The filter is delivered in a small box. In addition to the filter, it contains a filter chamber with sponge, air hose with valve and tube for the outlet nozzle. The filter is very well made and assembling the filter is quick and easy without instructions. I installed the filter in my 70l tank and it does a good job. Cleaning is quick and easy. The filter runs very quietly, which is particularly important to me. I'm very satisfied and am therefore giving it 5 stars★★★★★

Hi, so far it works soo good. Only one thing what I would like to mention. The power cable is a bit short. It could be and extra 30-40 cm longer.So far so good.

The Internal filter does more than I thought it would, I initially ran it for a while in parallel with my old filter so that it could build up the bacteria. After two weeks of testing in solo operation, it does what it promises. All values ​​in the aquarium were OK. The filter is relatively quiet, but that depends on how much I adjust the oxygen supply. It's easy to clean and reassemble. The price-performance ratio is excellent

It worked ok for a few months, then suddenly stopped working- Cant seem to find any guarantee detailsI wish I had bought a more reputable brand from a local shop!

I took this filter for my fish tank but it doesn’t work good I’ve tested for a month only during the day because during the night you can’t sleep because of the noise. The pump looks good and nice design but is not ok regarding the noise and the power of blowing ( blowing the air is too powerful )and if you try to cut the air the pump will start to heat even if you slow the air from the adjustable flow control.

My order arrived quicker than expected. It works perfect. I had the smaller version and decided to upgrade and it made a massive difference to my turtle tank. Easy to clean and easy to install with minimum effort. Seller is great.

I brought this filter as a quick buy, as my normal one suddenly stopped working! I must admit , I was sceptical when I saw the size as I was expecting something bigger like my other one. However needs must! So I used it in my 200 litre aquarium, and so far have been very impressed how it performs. I have only had it a few days so can't say about its longevity! But for now it certainly does the job until I get a new one of my usual brand! There is also a choice of nozzles that come with it. I change these at different times to change currant . One does a steady flow and If used correctly it is very quiet. The other is the bubble nozzle, Which produces the usual bubble making sound but nothing louder the normal. They even provide extra tubing, so you can attach it to the bubble nozzle so a have greater choice for positioning the filter and therefore the flow of bubbles, I would recommend this filter. It's cheap enough to buy and keep as a backup in case of emergency breakdowns like I had!!
