Hey everyone tonight i got my 3ft tank (36x12x15). My tetratec in400 filter is not even a month old and is made for upto 60 litres. Ive worked the new tank out to carry approx 127 litres/28 gallons, so my question is...it came with a fluval u1 filter, do I just put my tetratec media into the fluval? the fluval shape is different to the tetratec or can I get away with using my nice new in the middle of cycling tetratec in400 filter??
