Quikcrete gravel

Hey everyone I was going to set up a tank in a few weeks and I was wondering if this gravel is fish-safe as long as i rinse it first.The tank was going to be a freshwater predator environment.

Hello; Not sure about this gravel, but think the gravel used in many cement mixes is crushed limestone. A way to test is to drop some acid onto the gravel. I have in the past tested stones with some battery acid. If the acid fizzes and bubbles the stone ia likely limestone.

Ok, thanks, I'll try that test tomorrow.

can do the same test with vinegar.

Yup, vinegar will work just the same. Also much easier to get a hold of.

I use that gravel in most of my tanks and ponds. I used to love it because it was 4 bucks for 50 pounds but I'm kinda leaning away from it now. The rocks are pretty sharp and trap large particles. Its fish safe 100% but you must rinse the crap out of it.

Thanks for the help everyone, I already have vinegar so I'll use that instead.
