I am currently running a bb system that is established. I removed my sand roughly 6 months ago bc it was too fine and had a bb in the past. My 80 deep blue is shallow and I had issues with the fine sand. I am looking to go back to sand and always have loved the look. I know the pros and cons already, so not looking for that type of feedback. I have no issues siphoning detritus out on the black sand as I do it daily now with the bb. What type of black sand are you all using that is a large grain? I plan on adding 2 mp40's in the near future so the flow with the shallow tank will be quite a bit. If you have pics of what's working for you, don't hesitate to put them up also. Thanks
