Rocks

[adz2332]

i found a few rocks i liked the look of.
i did the vinegar / acid test and it was fine.
Is there anything else i need to know or check out with them? since the acid test came back fine?
or if thats ok they are good to go? once i have cleaned them

I am always cautious about this. I do have a lot of rocks from my neighborhood in my tank, I assume I am too late but I always test the rocks aren't going to screw up my water quality. I fill a bucket or something and test the water parameters and then leave the rocks in for a day and check the parameters again to make sure it hasn't done anything
