Zeo Carb

[Lunyone]

What does everyone think about Zeo Carb in a freshwater aquarium?

 

[Alice B]

it works for a short time in the filter. Zeo can be recharged in saltwater. Carbon cannot.

I assume zeo carb is short for zeolite and carbon and it's in a filter cartridge?
If yes, then zeolite will stop the beneficial filter bacteria from developing. This is due to zeolite adsorbing ammonia from the water. The beneficial filter bacteria normally eat ammonia and convert it into nitrite, and more bacteria eat the nitrite and convert it into nitrate. The zeolite removes the ammonia until it is no longer able to adsorb it, then you get an ammonia reading in the tank and the fish can die.

Companies use zeolite in filters to make you buy replacement items every month. Zeolite is not needed in most tanks but can be used in an emergency where you get a sudden ammonia reading and aren't able to do a big water change to dilute the ammonia. Besides that, it has no use in aquariums.

Carbon isn't necessary in most aquariums either. It removes chemicals and some heavy metals from the water. This includes things like plant fertiliser and fish medications. If you have other chemicals and or heavy metals in your water supply, you can filter the water through carbon before using it in the aquarium or for drinking and bathing purposes. However, if you do have chemicals and heavy metals in the water supply, you probably want to find a new water supply that is safe to use.

Thank you. That's exactly what I was wanting to know!!
