  • Rock Question

    I am getting ready to setup a new tank... 100 gallon.. gravel bottom, driftwood decor,, and some plastic plants... we will have Blood parrots, and prob some yellow labs,,, maybe some silver dollors.... the question is about the rock wall I am gonna build.. I plan on building out the corners and the backof the tank with a rock wall or sorts... I have located a rock called  "Rustic Ranch" and it is perfect for what I am going to do.. small light weight and able to stack like bricks.. here is a picture... does anyone have any experience with this rock.. is it high in metal content has any one used this? is there any way I can test the rock to see it there is any effects on the fish?  of coarse no one at the rock store (nursery) had any clues... they did add that they have used it in pond applications... here is a picture... this stuff is .20 a pound..    this piece is about  1.5" x 1.5" x 6" in size... nice texture... any info would be appreciated.. thanks  Cope
    Had about 900 gallons now I am tired and selling them off...

    What we have done is clean the rock really good and soak it for about 12 hours. Fill a bucket with water and test the water. Then add the rock and test the water again after about 6 hours. Compare the results.

    This looks like a type of limestone which we found raises PH.

    You can also put a little vinegar on it. If the vinegar bubbles it is an alkaline based rock (like limestone) and will raise PH

    Hope this helps.

      Try vinegar to see if it fizzes, this will tell if the rock has buffering properties
      Then get some pickling lime...build a paste and lay it on there. I found this one out by accident but it there are metals in the rock it will rust right away.

      Other then that I would soak it and test water before/after.

        this rock is very hard.. It does not "rub away" like a limestone or sand stone... I will test the water... so you think I would see a result in 12 hours?    thanks

          Yeah, the limestone we had was construction grade and was REALLY hard as well. 12 hours should be plenty.

            If you have access to it pressure wash the stuff....just to dislodge anything that could be there.
