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.

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.
MarkWhat 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.Fishtafarian- Fish are more than just a hobby, they are an obsession.
