BioCompact 25

I wanted a low flow filter for my fish tank which is a cubic 30x30x30 (cm). With this filter you can adjust the flow which is perfect for small fish and ideal for my betta fish. You can direct the flow in different directions with the added attachment and the filtration has been perfect for my tank, keeps it nice and clean in between water changes and when re-arranging my live plants. This filter is also very quiet which is perfect as the tank is situated in a bedroom. I would be careful when the handling of the filter, but it’s fine for me i just delicately wash the parts. Overall, impressed with this little filter.

for this premium brand it is a poor filter!!!! ISSUES- suckers pull off every time you clean it and are awkward to put back in place because they foul against the inner filter trays -filter flow is very poor mainly down to the design of the pull off motor head flow escapes from the rear around the joints - inner tray is flimsy and i can not see the joints lasting long (in my opinion ) a real shame as it is a nice looking compact unit !!!!

Neat little filter 👌

Sponge filter so small needs cleaning every couple of days but it's compact will do the job but I'm looking to change it soon

This is a great little filter for a small tank. I have them working in my small 25L tanks. Decent flow and uptake considering how small they are. They first appear small, cheap, and a bit crappy, but give them a chance. The sponges and granules both come out in little cartridges - like a mini Fluval. These filters are very good for their size and price. I've had one going for about 6 months now. Very reliable little things. The only downside is getting the suction cups on it - but maybe that's just a technique I haven't got!

My old pump gave up the ghost and I had to buy another one quickly before my fish died, they were struggling to breath and I felt really bad for them. I ended up buying a cheap temporary one while I waited for the Amazon one to arrive. I like my new pump very much, it is much better than my old pump, it is a better size and being grey it blends in very well. It is not noisy and so far seems to be working very well.

I purchased this as the reviews looked good , it’s small , didn’t do the job tank got in a terrible state using this item , and resorted back to my cheap filter ! The suction cups to keep the filter in place didn’t fit into the back of filter .. I wouldn’t recommend this filter to no one !

Small filter with a very poor suction power only useful for a small tank 5 litres or less.

Achtung für Bestellungen aus Deutschland. Der Filter hatte keinen deutschen Stecker. Somit für mich unbrauchbar. Für mich war bei der Bestellung nicht erkennbar, dass es hier verschiedene Stecker gibt. Sehr ärgerlich!

I have a 60 gallon breeder, which is 4ft long, and am running co2. I have 2 Aquaclear 70's on the back, so don't have an outflow that a canister filter provides, and obviously not able to use an inline diffuser, so needed something to disperse the co2 throughout the water column. I first bought a power head that was just way too strong, so took that out within a few minutes and started searching again. Found this and it's perfect. Pushing the co2 to the other side of my tank, but not flattening or ripping out my plants in the flow. Using it with an atomizer, which is able to be tucked right beside the outflow on this. It's also very quiet, which makes it even better.

Lo uso en paralelo con un filtro de cascada para un acuario de 28 litros aproximadamente. Me ayuda mucho a mantener el flujo del co2 en todo el acuario

absolutely love this thing, great for anything 5 gallons and under. relatively slower flow but thats ideal when dealing with nano tanks. also extremely sleek and not an eyesore.

Produit avec prise UK, j'ai donc remplacé la prise par une française (dans les règles de l'art, pas compliqué de brancher deux fils), au bout d'une journée d'utilisation, la pompe fait sauter le disjoncteur 16A de la prise sur laquelle est branchée la pomoe. Pas de retour possible étant donné que j'ai "bidouillé" la prise. Une idiotie de ma part de ne pas avoir utilisé la procédure de retour/remboursement Amazon qui est rapide est efficace. 1 étoile car prise UK pas précisé dans le descriptif et produit défectueux (nous avons une autre pompe oase à la maison qui elle fonctionne très bien, pas de bol)
