Hello my friends,
So I was chewing on an idea hmmm still am. When I set my tank up, I purchased live sand. Now I should have sifted it to get only the finest sand. I love the super nice soft sand beds. Well since I didn’t do that I have some areas that are nice and smooth, where others have old pieces of crushed coral, or rocks or whatever.
What’s the best way to get rid of this with out blowing my tank up? Stirring the sand bed is never really a good idea, I thought of moving my sand bed corals into a separate tub etc then scope it out, and sift it in a strainer and rinse with salt water.
Option B. Can I buy some really live fine sand, sift it and then added it to my current bed? Will the rocks and large particles that are there now just resurface again? Any advice would be great. I just don’t want to crash or spike my tank. But I really want the bugs bunny scene at pismo beach where all the clams you can eat. Super soft smooth silky sand![]()
Replacing a sandbed can be super tricky. Crushed coral is safer to replace than finer sands. I would decide what kind of sand you actually want and pick up enough to replace your sandbed with. Simply pouring new sand on top will just cause it to mix very soon.
Ensure the new sand is rinsed. Now use a large siphon and plunge it in the new sand. Try not to make a mess. Siphon out a portion of the sandbed down to the glass. Try to keep it as neat as possible.
Now with a pvc pipe, and a funnel on the top, plunge the pipe in the water down to the bare spot. Pour sand down the funnel and it will go right where it needs with zero dust storm. This will take a while and maybe require another helper. The sand will be wet so it almost needs to be flushed down the funnel.
Do about 20% or so of the sandbed every few weeks to allow the micro fauna to to begin to the restablish.
Two disclaimers. Don’t do this if you have a deep sand bed. If your sandbed is more than a couple inches, I’m out. I don’t know what to do there but the process will be different. Second. When I did this, I did cause some acropora tissue necrosis due to the rapidly changing bacteria levels. Fish and soft corals were totally unaffected
