Coral in Freshwater?

[The_Desacrator]

My dad used to have like a 200 gallon saltwater tank like 20 years ago. He used dead coral add decor. We still have them in the garage and I wanted to know if I could use them in my freshwater tank?

let it soak in hot water for 20 minutes, and it should be good to go. ive heard of crushed coral substrate so why not dead coral decoration.... but ive never used it so wait for someone that has

It would almost certainly raise your pH and KH. If you have fish that like hard water, then it shouldn't be an issue.

+1 there's nothing wrong with it, but it definitely will increase your pH. Also, it will break down over time unless your pH is a little above 8.0.
