Hey everyone! I currently have crushed coral as a substrate and am wanting to change to a coarse sand (caribsea special grade reef sand). I have been doing some research on changing substrates and there seems to be two schools of thought: 1) do it slowly in increments, 2) do it all in one day. I was thinking about just emptying the water into a bin, moving my rock (which has all the corals on it) and my livestock into that bin, and then changing out the substrate. Will I need to recycle the tank if I do this? I currently have a 10 gallon tank with one large piece of live rock. The CC is about 3 inches deep. I have a baby clown, a fire shrimp, some snails, two gold torches, a hammer, and some zoas in the tank. I am using an Aquamaxx Prism LED light fixture for light and am currently using a hang off the back filter and a Koralia 240 for flow and filtration. My parameters are: Ammonia- 0ppm, Nitrites- 0ppm, Nitrates- 0ppm, Calcium- 450ppm, Magnesium- 1400ppm, Alk- 8dkh. What do you guys think? Also, if any of you guys use the special grade reef sand, could you post a picture of what it looks like in your tank? Thank you so much!
