ceramic flower pot affects water?

[djork]

i was wondering if doing the ceramic flower pot cave thingy for my fish will change any water parameters such as ph or hardness?thanks

The ones here don't. Not sure if being down under will make a difference

I just put one in today for my corys to hide in, Only the snails seem somewhat intrested in it. Although once its covered in java moss it should look pretty good. I doubt it should affect the water parameters.

I use one with my convicts and they don't care. But then, my convicts live through anything.

as long as its terra cotta and not glazed, it will be fine.

Terra Cotta pots are fine. If there is glaze on it - colors, it will harm your fish. Glaze has copper in it.

I'm taking ceramics class in high school. I plan on making a small bridge as an ornament for my tank! No glaze though.
