Tiles that are safe for fishes

[JPEE 15]

Hi,

Happy Easter everyone!

I'm looking to start a white tile bottom fish tank and was wondering if anyone could recommend me a type that they have been using? A link from Bunnings would be appreciated.

Thank you!

No experience with tiles in an aquarium.  However I am a licensed builder and have done my share of very large water features.  

I would be going with a fully-vitrified (porcelain) tile and epoxy grout.    Normal grout is cement based and not suitable for immersion, normal grout is cement based and will be alkaline also.   Glazed clay-biscuit tiles have high water absorption and are not suitable for immersion.
