Sea Shells In Tank?

[happyannie]

I'm curious what others think about putting seashells in tanks. Do they change the PH level? Up or down? I put some in my new tank recently.

they shouldn't be in your tank
especially freshwater tanks
they are SEAshells, made from SEAcreatures, not fresh water creatures
they will effect your water chemistry

here's an old thread about them:

No, you musn't keep them, they will raise your pH (over 7). That said, I have crushed shells in my substrate, that I find almost impossible to remove. But I've had no problems, since I pump in CO2, and the pH of my tank is between 6.5 and 7

They can be added to some cichlid tanks.

I have some of them in my 5gal tank - but I also have like 2 small pieces of driftwood to balance everything out.

Thanks again!
