Filter clogged overnight?

Hello,

I have a 120-liter JUWEL aquarium. The aquarium has been running for over three years now, and I have the same problem: the filter is clogged.

I want to clean it as infrequently as possible, but after about a week, barely anything comes out of the jets. At night, the water surface is almost still, and my neons are at the surface, gasping for air. Then I clean it as quickly as possible and turn on the oxygen stone.

I'm starting to lose track of what could be wrong. I've tried everything. I only feed it once a day… nothing stays on the ground. It's also densely planted.

I can't clean the filter every 1-2 weeks… Do you have any ideas?

I only have a few fish left at the moment. I wanted to restock, but I'd rather not until the problem is resolved… I currently only have 2 guppies, 2 bristle catfish, 2 neon fish, and 2 blood tetras… I had over 10 of each, and yes, those are the rest that's left… The guppies strangely disappeared overnight, and the rest were over 3 years old and then died…

Hello,

the pen () has written everything right!

I think that

the fine thin white tile thing inside.

the evildoer is, because the fine fleece is fast moving, usually it is enough to clean it and leave the other inserts untouched!

Yes, filters must be cleaned regularly. Who doesn’t want to get a room plant but no auquarium

And not only the filter itself but also occasionally the pump has to get out. It must be taken apart and above all the small magnet in the motor thoroughly scrubbed. The pump loses its power.

In addition, after so many years the filter media have to be exchanged. So the sponges. Yeah, it’s pretty good to run it. But you’ll never get it right in. That means it’s getting difficult water running through there.

The paired with a pump that can no longer bring the original power leads to the water no longer moving properly.

And especially funny is fish mortality in poor maintenance now also not really…

After you didn’t write it into your question, I can’t smell what you did or didn’t do.

What filter is in the aquarium, and what filter media do you use?

I have the internal filter of the same brand at my Juwel Aqua, and it lasts well 2 months until the performance leaves and the sponges have to be flushed out.

Do you exchange the greens (Nitrax?) and the blacks (coal) regularly? Activated carbon is actually only necessary if you want to filter out drug residues and pollutants, and after a few days you have to remove them again because the coal otherwise releases the collected pollutants back into the water (so basically “overruns”).

The same is probably true for the sponges to filter out nitrates.

In my filter I have 2x coarse and 2x fine sponges and one basket with sintered glass tubes and zeolite. The system runs top.

Do not use this “flute” for the outlet, where the water runs from many small holes, but only a small tube with a bend. The stronger movement of water brings more oxygen to the basin.

Should be.

No coal filter sponge should be used for so long. It’s urgently out, just like the others who are specifically designed for pollutants.

Did you clean the pump and the pipes or only the filter media?
