Might be some good news I have bubbles coming up from my sand bed! Please, be good please be good and be what I think it is, LOL!
How deep did you say your sandbed was?
Look in my sand on the edge of my glass where my Hermit crab is walking. You will see bubbles in the sand and bubbles being released by the hermit and floating up and being blown away by my current. That is nitrogen bubbles.
Nice video... What is your Question? let us know what you know and we can try to help you from there. Those are nice nitrogen bubbles in your sand.
It looks like your sand is working as fast as it can.... you either need more rock or some plants or to have less livestock... because your system is out of balance... do you have a refugium?
