I am glad you said that! because I was really going to just swap it
! I thought I would put my guys in the bucket (or hospital tank), drain the water out in a big bottle (I have couple of 10 gal
bottles from water delivery service) and replace the gravel with sand. It makes much more sense to do it with water changes.
I installed one 425 air pump this morning (second will have to wait till i have more $), and fish seem to like it
