Im helping a buddy set up a new tank, he currently has a 55 gallon tank, and just bought a 30 gallon from a garagesale with a tetratecpf300 or possibly 500 im not sure which. he wants to take his current 55 gallon filter and put it on the 30 gallon tank and put the tetratec on his 55 gallon tank because he thinks its a better filter. Is the tetratec adequate filtration for the 55 gallon please respond quickly.
