i recently rescued a fish tank from a house move which had 3 gold fish and the fish are fine but the pump is missing a lengh of tubs for the air bubbles i have been looking around for a replacement tube but was wondering is the pipe on the motor is a standard size as as i dont know how to measure it i have seen some tubing from OKorder but i rather check first as i dont want to buy the wrong one the fist tank is a Marina Cool 21L Blue the tank was also missing a light which i recently purchased a Marina LED Light Unit the motor works fine as long as the air intake is just above the water line the pipe is about 1/2 inch in lengh the motor is submersable any advice would be greatly appericated stephen
using standard size plastic tubing like other air pumps on the market (about 5-6mm in diameter)
