I"m planning on getting a 125 from either glass cages or a lfs and I'd like it drilled so I can use a wet/dry. Why are the overflows always long (and quite large) black boxes? Why can't it just be a bulkhead with some pvc piping up to the desired water level with a strainer on it? On another note I plan on turning a 20 into a wet/dry with some scrubbies and using 2 aqua clear 110s, 1 for mechanical, other for biological. Do you think this would be enought for a 125 or should I add say a rena xp3 to it?
