Tadpole tanks need to be cleaned quite frequently, if you cannot clean the tanks because you are too busy then just clean the water and scrub the sides with a wash cloth. DO NOT USE SOAP WHEN CLEANING YOUR TADPOLES TANK, it will cause them to die, just a little bit of soap could be deadly . Use warm/hot water to clean your tanks. make sure the tank and the water your tadpole is ijn is very close temperature because if the water is too warm or too cold then your tadpole could go into shock. (we do not want that, it's bad). Tadpole environments: it is best to buy some fish tank pebbles and put them into the tank for your tadpoles to burrow into and climb on. if you cannot get pebbles then put a few rocks they can climb over.when morphing young froglets (tadpoles with arms and legs) it is necessary for there to be a lid (make sure there are tiny holes in the lid for oxygen)so your young froglets cannot jump out of the tank. You will also need to have a slope so they can get out of the water when they need to, otherwise they could drown.
