Aquarium decor question

[Ryan Depoister]

I have read mixed reviews on this. How is everyone on adding a couple shark teeth to the aquarium? Like I wouldn’t do any fossilized megaladon or anything but was thinking just a couple from a mako or bull shark but I don’t want to throw the water out of wack.

If I'm not mistaken, a sharks tooth is primarily just calcium. You may not want to use them if they've been treated or preserved in any manner. Depending on your tank size I doubt you would notice any effects. Just my opinion and others may vary.

Stuff like that will end up with algae growing on it. The same will happen if u put shells in your tank.
