The next generation of Oase Biomaster (Pro 2) is coming.
From what I can see, the main features are:
20-25% increase in flow performance.
Improvements to maintenance of various parts of the unit.
Changes to the piping colour and spray bar. (More of a glassware look).
It looks like Oase just upgraded and changed components within the confines of the current footprint. This is a shame, as I would have liked to see the small footprint increase slightly to enable more media containment.
(Edit - clarify, boring from Oase, I was quite excited by this post to see they were developing something new)
I’m a massive Oase fan (I have three) but this feels like a marketing gimmick more than actual innovation on their part.
Admittedly, they’ve got a great design already but this feels like a missed opportunity to create a connected canister filter with some great tech in it like flow and temp sensors.
This might seem gimmicky (especially with every single thing having an app these days) but consider some of the benefits like:
1. Warnings if flow drops or changes drastically in a short period of time - catch leaks and detect when cleaning is required)
2. Warnings if temps overshoot a desired range (admittedly this is a more pressing issue in warmer climes - my lounge can get to 35C in summer).
Maybe you get closer to that 1250L/hr figure now?!
Although, I am becoming stronger in my belief that the turnover of a filter (in terms of cleaning the water) isn't as important as we are led to belive. The problem comes down to when you need flow for plants, and a weaker filter flow means you have to have more gear in your aquarium to create that flow.
I’m very much of the belief that Oase know exactly what they’re doing with their filters. I love mine. It’s a filter, not a flow creating device. Seems to be loads of people wanting to push more water through them and have more media. 45ppi foam has a surface area of something like 1,600 m2 per m3. That’s the size of eight tennis courts! Something like K1 biomedia has half that. I think people would be surprised by just how much waste a foam filled canister can handle. BUT it needs a certain dwell time, so trying to push more water past the media, or having vast amounts of media, is counterproductive. Select the right size filter for your volume of water, and add other pumps to generate more flow. Don’t try to get your filter to do two jobs.

Honestly surface area is a total red herring, realistically dissolved oxygen is the only parameter that counts.
I've had the good / misfortune to visit a lot of sewage works and if you can treat raw sewage without any permanent filter media, but with a huge amount of churn, you can definitely do the same with aquariums.
Kaldnes K1 media was developed for the <"waste water industry"> and <"floating cell media"> is overwhelming the weapon of choice in aquaculture etc. This is mainly because the media is designed to shed excess biofilm and retain an optimal depth for nitrification.
Yes, nitrification is almost never limited by physical space. The reason that a lot of canister filters work at a fraction of their capacity is just that the water becomes deoxygenated in the canister and then oxygen can't be replenished in a sealed container.
That is also an untruth peddled by the vendors of aquarium filter material. It is true for the anaerobic denitrification of nitrate (NO3-), but the reason for that is back to oxygen.
Not necessarily. I’ve not opened my Biomaster 600 for a good 4 months now. Just need to clean the prefilter every two weeks or so. That’s a simple enough job.

I am really unconvinced of the need for a filter in a mature planted aquarium. If you take out all the filter media and just keep the flow does anything obviously bad happen?

I am not so sure because of the number of variables. For example, if you have a heavily planted aquarium + heavy fish stocking + very strong light, I think you need all the help you can get. i.e. great plant mass and a filter.
I have been examining the technology versus plant approaches and coming to the conclusion that, depending on the variables, there is a very good use case for both. It feels more like technology in a planted aquarium is a very good adjunct to plant mass, adds contingency, adds flow, and supports a more stable aquarium. Which is quite a step forward for me! As I was the 'Technology Approach' camp before meeting all you great people!! 😀

I’d tend to agree with you in terms of the smaller tanks - the small water volumes and filters volumes mean that there really isn’t much in the way of filter media for filtration, and the water changes remove the majority of waste anyways.
Larger tanks do get some level of benefit from the filtration aspect in my experience. As you cannot get all the waste in a single water change, and the filtration volume is a lot larger for helping with the waste control.
I like to syphon any organic waste, I really don't want it in the filter. I actually have some mulm in the tanks, again I see <"it as a positive thing">.
"All the filters got a complete redesigned and widened outlet to increase the waterflow. The biggest one in the family (BioMaster 850) also received an improved impeller/rotor."
"We especially talk about the waterflow inside the head, which we widened and optimized. Together with the optimized prefilter and a way better outlet for air, the waterflow in total is way better now."
You get to see it a bit more in this vid from an ordinary customer, kind of an unboxing, and he compares it to the old one. The "new" pre-filter tube has been available for a while now and even before that everyone was drilling the old ones out. The main new difference (as mentioned above) is the flow path through the head unit. Presumably the new head unit will retrofit to the old buckets...
In car terms this Biomaster is the "facelift model" - a mid lifecycle refresh to iron out a few bugs and offer a slight cosmetic upgrade. The chassis (bucket) and engine (motor) remain the same, as do the majority of the parts used, some trim gets changed out for more modern looking equivalents and maybe the suspension (inlet tube) gets tweaked and the transmission (head unit) gets replaced with an updated version.
I think it will be another 4 or 5 years at least before Oase consider a full redesign (if they ever do).

Agreed. I really think if Oase can add a little more to the footprint, then they could be going somewhere.
Even in my tiny little aquarium cupboard, adding an extra 2 inches to the width and length would add another 170 cubic inches of biomedia capacity. Which is the equivalent of having 2.5 more 20 PPI sponges in the 350.
