I would love to see you test an Oase Biomaster 250 vs Eheim Pro 4 250. I have done this test myself and determined the actual flow rate of the Oase to be 336 liters per hour, whereas the Eheim literally did double that with the exact same amount and type of filter media in it.

Please do a dedicated video. I have enjoyed a number of your other reviews and would appreciate it. Oase is less common here in the USA, but I have been looking at the BioMaster Thermo series for a while.

did you leave any sponge in the filter or did you fill the filter with organic media and left only the sponge in the pre-filter?

dunno if you guys cares but if you guys are bored like me during the covid times you can watch all of the new movies and series on instaflixxer. I've been watching with my girlfriend for the last couple of weeks =)

@Alberto Kace definitely, I have been using instaflixxer for since november myself =)

yes replacing some of the media for biological is a good choice

@@JurijsJutjajevs the heater is necessary if the room temperature does not fall below 22 in winter. I can buy the non thermo version much cheaper.

Don't rush with maintenance. 6 month intervals at least. Most of the gunk stays in the prefilter and main media stay clean for a long time.

Good choice, video coming soon

cool, thanks for being a loyal viewer of our channels 🙌

luckily I wasn't the only one 😂

you welcome

you welcome, I knew I was not the only one

I think I will make separate video for the filter itself and another for the comparison

It poops on those filters just by having a built in heater alone. Haha

Can you explain that? I don’t understand what you mean

Jurijs Jutjajevs I think THE PLANTED TANK answered it. Is it better than an Eheim or Fluval canister filter and if so, how do you think it is better? U

Personally, I'd take an Eheim pro filter over one of these Biomasters any day even though the quality of the Eheim pro has been going down slightly with the later revisions. The prefilter is done all wrong with very fine sponges and then you have coarser sponges inside which doesn't make any sense so you have to cut out your own prefilter sponges out of the sponges found in the filter unless you want it to clog up and lose flow pretty quickly. The trays have really flimsy quality plastic and it's a bitch putting it back together after cleaning. Also I've heard that the built in heater has issues going way above what you set it at, but I can't confirm that as I haven't used the heater because of that. Also very poor selection of biomedia that come with the filter. You don't put plastic media with basically no surface area inside a canister and call that biological media. Really cheap by Oase. Four advantages over the Eheim. It has a really good and sturdy handle for carrying. It's easier to prime. It's cheaper. Built in heater. The Eheim also have multiple o-rings that needs lubing otherwise it will start to leak eventually, especially with the bigger models like the 2078 from my experience. Haven't had the Oase long enough to speak about leaking issues but so far so good. Also, you can't use the priming button too vigorously with the Eheim 2078 or it will start to leak.

thank you for watching

Great filters, love them

@@JurijsJutjajevs It's here and it's beautiful! Now the wait for the rest of it... I can't wait to get scaping!

you welcome Terry, this is like tailor made content for you and your future aquarium 😉

Great tip but it does not help me. When are these filters coming to South Africa? Enjoy your videos

Oh sorry to hear they are not available for you. I don’t know this, please contact Oase customer support

who reads instruction manuals? 😂

you welcome and I'm happy this was useful for you

now you can keep the hoses on 😉

Does this feature also on the filtosmart series?

you welcome 🙏 😃

haha 😆 so that's probably just me. but honestly, I talked to so many people and complained about not having this feature and no one was able to tell me about this feature

after replant slowly growing in

You welcome

anything specific to be covered in the review video?

Jurijs Jutjajevs sure. * filter media order. The factory one seems to be illogical a bit. * filter media choice in your setup. Did you keep the factory media? If not, what did you put and in what order? * any tweaks that you made to improve filter performance? * factory inlet/outlet review. * pre-filter. Did you change anything there? * anything I did not mention :) For example I’ve removed one blue sponge, all the bio media (the plastic one) and changed it to ceramic rings; drilled some additional holes into the pre-filter pipe; changed pre-filter foam to more coarse (from blue to orange). My biggest concern is which OEM outlet is most effective on my 60x60x40cm cube where I’m keeping 10 lamprologus speciosus ;)

you welcome

omg Tass I'm so happy I'm not the only one who freaks out about it 😆

glad to hear you have it for several years and you are happy with it

do you mean which Oase Biomaster is best for which tank size?

This is soooo weird!!! I would not have known but you ♥️ this. I did NOT write this post.

I think thermosmart is one to go for, as the Biomaster is too big and too strong for a 30l nano

immer gerne Mona

hehe, you welcome, I knew I wasn't the only one

Glad you like it!

Neo media from aquario. It works fine I guess. Difficult to measure how well its working compared to others. but I'm happy with it. The scape I'm using it has had no issues in the long run

Never tried. I think it has to be replaced

I loved this feature on Eheim prof 3/4 to drain water from aquariums for a quick water change

you can use the a 16/22-12/16 adapter for a smaller outlet, inflow should remain original size

Jurijs Jutjajevs thanks!!

Biomaster 250 of you want something big, or check the larger filtosmart series

@@JurijsJutjajevs Thank you with appreciation elias

you welcome

You absolutely right but the noice make fish stress and watching aquarium is not a joy all becouse the noice.I give it 6/10

what hose diameter does fluvial come with? they used to have a different size, which is why I never tried one

@@JurijsJutjajevs it's 17 mm, the hosing is the worst part of the filter, is kinda weird and cumbersome, but other than that it's a great filter, love your videos mate 👍

There is nothing I can suggest, please contact your local Oase dealer

You could try using clear silicone grease with PTFE on all of the rubber gaskets.

I would be very careful with this - because if you turn the valve too much, it can disconnect and leak . also by doing so you not only limit the outflow, but also the inflow to the filter which can cause vacuum in the canister, which can cause air getting sucked through the seal, which again can cause leaking. Always control the filter only on the outflow

Thanks 🙏 yes I will make that video

exactly, it also mentioned in the manual

Are you cleaning prefilter regularly? In case you dont underpressure builds up and can be filled with air which can cause the noise

@@JurijsJutjajevs well I’ve found out it was the heater when turning on n off what was making the noise it’s really weird noise but called oase today and they confirmed it was normal still don’t understand if it’s “normal” why is it that some people get it and others don’t thou, never mind thanks anyways 👌🏻👍🏻

Just rotate the lock handle instead

@@JurijsJutjajevs thank you 🙏

Good old Eheim can last many years 😉 if you really want, you can sell your Eheim and upgrade right away

you can call it a downside or call the prefilter extremely effective! simply clean your prefilter more often, that's what it is for or replace the prefilter sponges with some that have a larger size. I remember George did it once,,

@@JurijsJutjajevs I think i'll 3d print some pipes, so i can experiment a little bit. But for sure, the prefillter works pretty good, also the water is crystal clear since I use the Oase Biomaster

Yes drilling holes in that pipe inside the prefilter might help too

what is the best you like about them?

The integrated heater is really nice for aesthetics, plus the prefilter is so easy to maintain

oh thats a good info, I'll try that

😉

anything in particular I should cover?

I would like to hear your thoughts and experience on the below: 1. How reliable is it over a long period? More than a year or so.. 2. I have read reviews where folks complain about the filter making purging noise often and also the heater not working consistently. Have you faced similar issues? 3. Are the prefilter holes sufficient enough or would you suggest drilling more holes? 4. Will one Biomaster 600 be sufficient for a 120P or will you recommend two? Thank you!

its hard to go wrong with these filters. Is there any specific questions you would like to see covered in the review video?

Jurijs Jutjajevs how would you adjust the flow on these filters I don’t see any valves I’m looking to put one on a 20 long.

Original Oase outflow pipes come with a flow control tap. If you replace with a lilypipe you don’t have it anymore. In this case you need a tap build into the Hose. One from eheim 😆

Jurijs Jutjajevs Thanks so much that’s what I though 👊🏻

🙌

Ich meine ja, habe es aber nicht probiert. Was auf jeden Fall geht ist den kompletten Filterkopf vom 600er oder 850er auf einen kleineren Kanister zu setzen, das passt immer

@@JurijsJutjajevs Vielen Dank für deine Antwort.

they are both good filters. Oase has a build in heater and prefilter, while ADA is build to last and has power that kind of never stops. Its very hard to compare both as they are completely different. Also price is different. it really depends what is more important for you.

No filter is the quietest. Single models can vary, a simple test with only one filter of each wouldn’t be accurate.

@@JurijsJutjajevs how is the oase bio 250 can you sleep in the same room if its about 40m2 and to not bother you while sleeping?

Make sure your prefilter is clean and nothing is blocking the inflow. Gently syphon on the outflow of the filter, it should start the filling process

@@JurijsJutjajevs so every time i have to clean the filter i must remove the hose and syphon the filter?

@@JurijsJutjajevs how to make the filter silent? I have the active bacteria material on top in the filter like #aquaowner said.

Steffen K wenn der Pump Kopf nicht ansaugt, dann ist dieser vielleicht defekt. Am besten an den Händler wenden der dir den Filter verkauft hat.

haha 😆 I'm ok if people make jokes about me, its a fun hobby and I don't take it too seriously

the skimmer is a different topic. as for comparison I think its best to compare with Eheim prof 4 thermo, would you agree with that?

Yes, no problem. I like a good filter but also very quiet.

good morning : ☀️ 😉

@@JurijsJutjajevs Hehe, perhaps a bit late to wake up xD Btw. The Video is great as always, really helpfull! I think I'll upgrade my bad gunky Superfish xPro 400 because it is so ANNOYING!😂 The Eheim Classic 250 ln the other tank is great, but no thermo function unfortunatly😰

I love the eheim classics, but they don’t have any features

@@JurijsJutjajevs That's true! So I think I'll be very happy with an Oase or so!💪

Not really, what I’ve observed over the years that same filter is having more issues in one tank and less in another. So partially that’s bubbles from the water and partially from bacteria inside filter. The newer models of the biomaster have a little feature build into reduce the amount of trapped air, but I have heard users still having issues despite this feature. All in all, it’s annoying when you focus on it, but it doesn’t harm neither the filter nor the aquarium system as a whole. Other filters have other problems, in the end its matter of choosing what features you like and accepting the downsides of the respective filter

@@JurijsJutjajevs Many complaints about loosing the injected co2 because of the air bubbles in planted aquariums.

biomaster purping issue has no effect on CO2 inside aquarium imo, its just annoying to hear the sound and see an occasional burst of bubbles, but its nothing compared to a skimmer or proper aeration

with this filter? it won't let you close the valve on the filter if the quick connector hasn't been moved back

Jurijs Jutjajevs yeah, but I’ve opened the valves before disconnecting the lily pipe and skimmer for a first hand lesson of how syphoning works.

Oh 🤣 welcome to the wet hands club 💦

Jurijs Jutjajevs 😂

nice 👍 keep on maintenance 😉

@@JurijsJutjajevs by the way love oase filters, hopefully will be able to get one in future if international payment will be allowed in my country until then it will be like a show piece in museum 😲

International payment restrictions suck

I must be lucky, my filters are perfectly silent, unless some air is trapped inside from the skim pipe

Yes if you buy the thermo version. If not you can upgrade afterwards, this is possible too!

@@JurijsJutjajevs Thanks! btw I bought a 60x30x36 aquarium, the Oase 100 should be enough in terms of water flow right? Cause the 250 for example sounds to me a bit of too much water flow and might be unpleasant for the fish or no?

yes I know, I did the same with my old Eheim filters. They have a tap in the quick connector.

haha 😆 cheers 🍻

sure, be more specific about what you want to see in this video

@@JurijsJutjajevs how to fill it with wich media. Wich pre filter to use in wich situation. Use the full capacity of the filter for a smaller tank or putt a divider between.

haha, maybe from now on you will 😜

thank you, I will consider this
