Greggle Posted June 30, 2022 Share Posted June 30, 2022 happy thursday, all. i've been using black diamond sand in my tanks and i love it. i want to switch the substrate in my betta community tank to sand from pebbles. i have a second, identical empty tank (10g). my plan is to put the cleaned sand into the empty tank and move everything over, unwashed, to the new tank, matching the same set up: plants, rocks, heater, sponge filter. i realize the gravel houses quite a bit of beneficial bacteria, but would the transfer of everything else be safe enough for the fish? 1 Link to comment Share on other sites More sharing options...
