  • New layer of gravel?

    Do you think a new layer of gravel will upset a tank? I want to add about 1 inch of a different color gravel to my well established (4 years old) tank, But I dont want to shock the system. I cant think of how it would but just want some opinions.

    I think I've done worse to my tanks than putting in an inch of new gravel. I'd go ahead and do it if I were you. :)
    Fish are people too, they just have gills.

      Depending on the substrate you already have, it could possibly kill off any nitrifying bacteria in the current substrate. I'd keep an eye on ammonia and nitrite for a couple days after you add the new gravel.

      What are the facts? Again and again and again--what are the facts? Shun wishful thinking, ignore devine revelation, forget what "the stars foretell", avoid opinion, care not what the neighbors think, never mind the unguessable "verdict of history"--what are the facts, and to how many decimal places? You pilot always into an unknown future; facts are your only clue.

        Make sure the gravel is not too hot or too cold before putting it in as it could temp change the water.
