Will these work for both freshwater and saltwater?

It can only work for freshwater aquarium. Put it into saltwater aquarium will increase the level of nitrite. So, we do not suggest to use it in saltwater. Thanks.

why will this increase nitrite in saltwater tank? Wouldnt it grow nitrifying bacteria like in fresh water?

Per the instructions not for use in salt water

Has anyone used this as thier only mechanical & bio filter? It says it can be used as both...

I would not. I have mine in a overstocked cichlid tank with a sump. I have sockfilter to remove large debree right before a wall of these blocks
