I thought i would post this in another thread. I would just like to know if the bubbles in my DSB is normal and if its okay for me to run my feather worms on my DSB or if i should put some egg crate in and put them on there? They always going to move. Basically Yay or Nay. Ive seen alot of change in this DSB in the last year. Its amaing to watch.
