BioMaster 2 Thermo 850 Canister Filter for Aquariums – External Aquarium Filter with Built-in Heater – EasyClean Pre-Filter, Quiet Operation – Freshwater & Saltwater, Up to 225 Gallons

El mejor filtro de todos

So far, this canister has lived up to its name. The setup was not bad; the only time I ran into trouble was closing the latches back, which was hard and worried me, but I got them to close. I put the rubber mats down to reduce the noise, and we can't hear it at all, even in the living room. It came with a ton of media, which I rinsed before putting it together. The priming button, or whatever you call it, is amazing to push, and it filled up without an issue. This has been my easiest canister filter setup, and I have used many brands, and by far, this setup was the easiest. I had it set up and working at the 30-minute mark. I am very happy with this purchase. My aquarium is pristine, and I have 2 mature L097 Polka Dot Cactus plecos (not to mention 20 Colombian tetras), and they produce a lot of waste. So far, this canister filter has been effective at removing waste, and the aquarium's nitrates remain low. It's pricey, and I got the one with the heater already installed. It performs as expected. Great canister, again a bit pricey, but you get what you pay for.

soo good . You guys gotta guy this

Tab broken. Arrived damaged. Returned it and got charged $20 more. Don't feel like fighting over it. Packaging is poor, doesn't protect delicate tabs. We'll see in round 2.

works as expected

I normally only use Fluval Fx6 filters however I’m starting to cycle a 150 gallon aquarium which I plan to use for discus fish. The reason I opted for the.Oase filter this time around is because of the easy changing of the pre-filter discus fish require very clean water and the FX six is a bit of a nitrate trap so I would constantly be opening up that FX six canister rinse out the filter, pads and sponges. The idea of just pulling up the pre-filter and rinsing it and putting it back without having to open up the whole canister is a huge plus however there are some things I’m not very happy with the turnover rate is nowhere near that of an FX six so I would need two of these on my 150 gallon tank so that’s over $800 to filter the tank. Also there’s no light that goes on to indicate the heater is working properly. I use a heater controller and plug this heater into the controller as well as a titanium heater rod inside the tank. This way both heaters will function through the controller. If one goes down I’ll have a back up however there’s no way of knowing whether the heater is working or not working, there’s no light to indicate such. It seems very strange to me. I’ve never seen a heater without a light to tell you whether it’s working, certainly not one inside a canister that definitely needs a light. I just plugged it in a couple of days ago and started my cycle so I have no long-term experience to compare this with any other filter but right off the bat those are too big things that should be fixed, especially at this price, a higher turnover rate and a light to indicate whether the heater is on or not at this price point those two things should’ve been addressed, especially since this is their second iteration of the same filter very strange I’ll come back to this review after a few months and let you know how it’s doing. I’m debating putting an FX six on this tank though because one filter is not going to be enough biological media for the discus Tank

Love this canister filter. Have used several other high end brands in the past but the Oase biomaster 850 is the best so far. The ease of use, cleaning, and startup is excellent. Have 2 of these and one Oase filtosmart 200. I recommend all of these filters you will love any of them.

Vroegtijdig geleverd maar tiptop in orde

Sehr leise im Betrieb, Filterung ist bis jetzt sehr gut, das Wasser wird klar, die Verarbeitung des Filters ist sehr gut, alle Filtermedien sind dabei, Heizstab! Nun da ich ihn frisch angeschlossen habe und parallel meinen alten Außenfilter auch laufen habe wegen der Bakterien, warte ich mal ab auf Langzeitbetrieb, ich bin sehr zufrieden, zumal eine kleine Reinigung jederzeit einfach erfolgen kann ohne den ganzen Filter auseinander zunehmend!
