Regarding gravel replacement -- over the course of a week siphon out the gravel 1/3 at a time and replace with your new gravel -- that should give your bacteria time to grow on the new gravel and prevent a mini-cycle.
Good luck!
randomlugia;3759896; said:I also agree with new gravel. I would scoop it out into a bucket, one scoop at a time. You might have to remove the decorations. Then spread the new gravel into the tank underwater, after rinsing it out.
That jack dempsey and goby will outgrow the tank before you know it.
