2 filters to keep an eye on.
Oase Model 350 and 600.
Oase (German origin) just hit the states in recent times as they are known well in Europe.
We like using the modified version of the Eheim 2217
Model 2217 is basically the 2nd largest Eheim aquarium canister. The next size up is a 5 gallon bucket size Ehiem canister.
The 2217 filter is a great choice with a German background which usually means the opposite of China as for desired quality standards.
A few quick modifications patch up some weak links or ways for water to get out that is typically discussed in reviews or forum threads.
I removed the Eheim 2217 cover, bypassed the hidden O-ring, and just used the direct output on the 2217 canister.
1 point of future leaking is reduced as well as the hollow sound helped by the fancy "motor cover".
I used to have have to set a bean bag on the top to mute the sound from the motor under the canister's cover.
Next, I will seal/glue the Eheim 2217 model 90 degree canister body intake tube that can to leak through the decades of service.
Seal all weak links. There shouldn't be any major reasons not to in my opinion.
We can always hide a slightly coarse foam prefilter on the canister's intake that is "in position" for easy slip-fit removal.
Tugging and twisting tight intake sponges in the tank can be a burden and leads to mess or frustration.
This foam on the intake pipe will allow us to keep that seal on the canister sealed a little longer.
-opening it up less times per year, by just tending to a pre filter intake sponge.
A spraybar aiming at the glass
displaces the jets to softly calm the high flow. No plants to get pushed over.
Plants are happy.
In the mail is a New Oase 600 model filter.
The prefilter cartridge in the canister is pretty neat as for the concept.
-time will tell.
This is supposedly a German product as well.
They just keep coming to the top when it comes to final purchase decisions on products.
I did avoid the heated "thermo" model.
The glass needs to cool before sitting still in a choked water tube.
I think people either bump or abuse the heater design.
By using a digital Inkbird brand controller and titanium heater with a black guard, I can say I am pleased with a small black stick-heater hiding without issue.
