Looking for used filter media

[Trev]

Hi, I have a new aquarium, with fish in it for 3 weeks. 3 days ago only nitrite level went up. From what I found online - the used aquarium filter media from an established tank will help to speed up the cycle. I’m changing the water twice a day, which stresses my fish and I am not sure if that helps to existing bacteria to grow.
I live in Eindhoven, can someone please advise where can I get the media (a near by fish shop doesn’t provide it), or maybe someone have it and can share. I will appreciate that a lot.

Have you tried asking at Heevis? They are a relatively well-known fish shop.

I don't live in the area unfortunately.

Also, how much nitrite did you measure? Up until a certain point, your fish will still be fine. Might give you an easier time dealing with this if you know the limits. Here is some more info:

You can add bacteria with Tetra Bactozym or Colombo Bactostart...

But the added value of those additives is doubtfull.....
Anyway he can get a liter bacteria at my place.

If you're in week 3 I wouldn't stress about it. 1 water change of 50% a day will suffice and not stress out your fish as much. If you're meassuring nitrites, it means you're past the ammonia spike so going in the right direction. Just a matter of time. Also, it's a hobby of patience. 🙂

Hello, thanks for the link. Yes I contacted Heevis, but they don’t sell filter media, only live bacterias. Which I am going to get now. The level increases every day by 0,2. Now it’s 0,6..

 

[Gino88]

I see. 🙂 Personally I'd advise against using "bacteria in a bottle" products for this use case. They don't generally do a whole lot, and nitrifying bacteria in particular don't transport all that well. (This is assuming they've even included the right types in their bottle product, which typically is not the case.)

Besides, there are lots of inoculation points for them in your tank already. They just need some time to develop.

I'd say lean back, monitor your nitrite levels, and consider using some table salt to replace the extra water changes you'd otherwise be doing. The article I mentioned contains instructions for that. 🙂 You'll be fine.

I would every day do a 80% water change until NO2 is 0.

Tell is please the measurments (cm lengte, deel, high..) and liters of the tank. And what sort of filter do you use?
Internal filter or extern?

I have a bucket of cycled media in Vlaardingen... Not nearby tho, I would also advise you to measure and do daily water changes

 

[Friesian]

I would also recommend patience and waterchanges....
Maybe for a week patience at least or else for 7 days.... 😉😀

 

[Trev]

Thank you everybody for info and giving me some optimism that it will be fine 😁.

It’s 30L nano tank 30x30x35. it came with cartridge filter. My concern now is that all information I found online says to change water daily. Yesterday I went to a fish shop (to pick up Colombo live bacto) and they told me that with constant water change the ecosystem will practically never settle.

That's BS. Fish shops have a motivation to sell you something, so they will nearly always recommend bacto starter stuff, but nitrifying bacteria need a surface to attach to for them to survive (that and oxygen). Water changes don't change anything in that regard, it just gets rid of waste and excess nutrients in the water column. Also, the cartridges can be a pain to deal with.

Thanks!

Dear @Trev
I think I understand now your problems.

I would recommend a bigger tank. For example 60 liter.
I would suggestie to take a look at the site Hornbach. A nearby store is in Best.

Please place a photo of your tank including the fishes.

"Bigger is better" natuurlijk, maar wat je hiermee eigenlijk zegt (als ik je goed begrijp hoor) is dat hij beter niet aan een nanobak kan beginnen? Ik denk dan: feit is dat die bak er staat, en er zal een reden zijn dat er voor een kleine bak gekozen is. Heel veel mensen houden met succes nano's. So why not. 🙂

Nou nee, niet helemaal... Met 3 vissen in 30 liter weten we niet wat voor vissen het om gaat. Er zijn nog mogelijk dingen die van belang zijn... En een grotere bak biedt meer mogelijkheden qua gezondheid van vissen.

Daarom zeg ik ook dat ik denk de problemen te begrijpen...

Daarom ook een verzoek van een foto. Een totaalplaatje biedt meer houvast..

 

[Gino88]

Duidelijk. Maar maak je het dossier dan niet groter dan het hoeft te zijn? 🙂 De hulpvraag van de topicstarter is simpelweg: help, mijn bak draait in en ik heb nitriet, wat nu.

Niet perse, dat is niet mijn achterliggende gedachte. Het verhaal achter het verhaal zoals ik meestal denk.
Misschien is met een totaalplaatje, het hele dossier completer in plaats van alleen groter?

Yes, that’s my plan for this weekend to get him a bigger tank. Totally forgot about Hornbach, will check there as well. Maybe it’s too early to celebrate, but it looks like the water is stabilizing. I didn’t feed for 2 days, and today gave a small pinch of food, so will see how it develops.

I started this hobby from the wrong end. I went to the shop just to look at fish, and all of a sudden one hour later I am at home setting up my first tank. So I started to investigate it afterwards. I will share a foto tomorrow. Already left the home

Sadly you are not the only one....LFS should have given you more information, but I refer to my signature: NEVER TRUST a LFS!
It is more work and a bit stressy for the fish, but mostly it falls at its place....

It's not necessarily wrong. I started that way as well; although the guy at the LFS at the time took his sweet time explaining the basics and wouldn't sell me fish until he had tested my water parameters after 3-4 weeks. It would be wrong it they sold you a tank and fish straight away. Which is what I meant with most shops will always have motivation to sell you stuff.
Btw, it's perfectly safe to still feed normal amounts.

With the tank I was given bacterias to speed up the cycle, but I brought water to the shop for checking after 2 weeks, and apparently it was good to get the fish. And something somewhere went wrong after 3 weeks..

 

[Lysia]

Two weeks is simply not enough for a tank to develop....

 

[Gino88]

Yeah it's a well-known phenomenon in this hobby that you won't necessarily see toxic substances in measurable amounts in all stages of the cycling process. They gradually build up and they fluctuate.

The owner of the shop that tested your water is most likely very much aware of this. But as you often see in the business world, money is king. They know that if they were to tell you the whole story and hold you off as a customer (until your tank is cycled) they may lose you to their competitor.

What I do is starting up my tank for 6 weeks without fish and without hocus pocus bottles.

I would recommend to order at the management of this community cans with patience. Unfortunately there is a waiting list... The factory who's responsible for the delivery is bankrupt... 😀

😁. Yes there will be no rush anymore. Lesson learned

Although 6 weeks is definitely on the safest side; common practice is to wait 4 weeks. after about 2 weeks, you can expect a spike in ammonia and 3 weeks for nitrites. When they're gone, you're set for fish - which usually around the 4 week mark.

One more question, do I understand correctly that I should add some fish food for bacterias while new tank is cycling?

 

[Gino88]

Yes it does help to actively feed the bacteria like that. 🙂 Both for establishing your nitrifiers (the ones that make nitrite and then nitrate) and for the bacteria that break down various organic stuff. They'll perform best when they've been trained, so to speak, before any fish are added.

 

[quistero]

Yes, just a little pinch once or twice a week.

 

[Friesian]

To make the story complete. Your completely right as the others already said. The bacteria colony will build up in your filter aswell in the bottom you choose. You can choose between fine gravel or filter sand 0.4 - 0.8 mm.
