Newb but eager to learn!
I took my rock out today to redo the scape and added water so that the tank could still cycle with pump on, after adding rock back in I took some water out knowing I would have too. I randomly hear a gurgling noise every 5-10 mins maybe more. Do I just need to take a little more water out? It's a 29g DT 20g sump (maybe 15g water in it), drilled with 3/4inch overflow
