Plants an fertilizers

[Asahmkow]

Hello,

Have anyone used pond fertilizer spikes in a planted aquarium?

I bought one called Laguna mini fertilizer spikes from a pet store, they claimed to be safe for fish.

But it's been a week since I added them and I'm showing ammonia and high nitrates on my tank.

Please can someone tell me if it's the fertilizer or is this is just a mini cycle?

Thank you

Not knowing what is in the fertilizer spikes and your water readings were fine before adding them, then I'd say most likely its the fertilizer spikes. I'd remove them if that possible if it was my tank.

Hello A...

If the fert spikes are for pond use, then there's nothing in them that's toxic to fish. If you're following a sound tank maintenance routine, including changing out half the tank water every week, then your fish will be fine. The large, frequent water changes will prevent toxins from building up in the water.

Done I took them out and made a 40% water change. I'll see tomorrow what my readings are.

Thank you

Well they don't say anything about nitatrates spikes in the water, but I have read some articles over the Internet, on different brands of pond fertilizers that some people complained about the same thing. That's why I ask

Thank you

Check the label to see if it uses ammonium nitrate as a fertilizer. Also, if you don't bury some root tabs deep enough, the will leak into the water column and cause issues.
