can i turn my internal power filter off at night or will this kill the filter bacteria. if so can anyone thinks of a way to reduce its current without affecting the tank too much? its a superfish 100 internal filter with spray bar attatched in a 20 litre tank. the tank is split in half and one half is split in half again. there's a male betta on the big part (1/2 of the tank) and a female in each small part (1/4 of the tank).
