    I wouldn't chance using it. Considering it's from a flower bed, who knows what chemicals its picked up.

    I would suggest cleaning them with a pressure cleaner, are you gona be starting a new tank with the rocks or adding them to an established tank?
    Perhaps dose with stability for a few days after adding them.
    Cheers man

    They use hcl. .Aka pool acid mixed with water (check online for correct ratio) then they add bicarb to neutralise acid..easy process but be careful when handling hazardous chemicals and take necessary measures

    After the acid wash, let it stand in a drum with water for a couple of weeks.

    I would not take the chance..it could leach any impurities back into your system at any time no matter how much you wash it upfront
