Ok I am getting a better understanding now. My sand is from lfs (texas tropicals), the rocks were once in an established tank but were out of water for 2 weeks (my fault). Before I put the rocks in my tank I put them in a tub with a ph and ran that for a week with daily water changes. Then I put them in my tank. I do water changes on the tank every two days. I also put a small rock in the from an established tank ( i crushed it up and sprinkled it on my rocks) What are your opinions on all of this?
