so I need to put some new sand back into my tank bottom does anyone know Ican do this without caissons to much hassle to the fish and everything inside?
Make sure to clean it free of dust before adding it. Once it's all cleaned up, turn off all of the flow in the tank and use a cup. Fill the cup with sand and gently lower it into the tank and let it fill up with water. Move it to the bottom of the tank and slowly pour the sand from the cup.
