I have a 144 gallon half circle. Has been set up for 8 months. My clownfish keeps throwing sand all over the tank and lands all over the corals. I thought about going bare bottom before I set it up but decided against it at the last moment. So my question is can I remove my existing sand without a huge impact on the tank and crashing it. My thought are to suck out bits at a time over the next month or so maybe once a week with a 5 gallon water change. Also for a bare bottom tank is there any additional filtration I need to help break down waste? And is it alright to have a open glass bottom or does it need to be covered with starboard? Thanks for the help
