    Question Red Sandstone Questions

    0 Not allowed!
    I am changing the environment in my tank to include one holy stone ( very nice cave- like formations on this one) 3 cichlid rocks and I have some red/iron sandstone that I would like to make into a formation. Here is my question though, I have researched and discovered in general sandstone is not good for tanks do to it dissolves after awhile. On the other hand I have read that sandstone with iron in it actually holds up very well. I have washed ( water only), scrubbed, checked with vinegar ( no fizz), submerged in r/o water for 48 hrs with the only change being a very slight rise in pH ( to 6.5 ) and ran through the dishwasher ( without detergents) with no noticeable breakdown of the rock. Do you think I can still use it in a tank or would I be better off without ( this rock is literally all over our property so I that's why I considered it). I plan on stocking tank with Dwarf cichlids and small pleco's or maybe Cory's

    I have sandstone in my tanks, and they look great, especially with a sandy substrate. As long as the pH change wasn't too extreme (because it rises and falls exponentially, not linearly), you will be fine to put it in your tanks. Way to be cautious and take the right steps to check your rocks.
