Oh its gonna work real well. pipe size... depends on the size of your tank and the power of your motor. IMO, use the bigger ones (2" and up) to be safe. They'll still work even if you upgrade to a more powerful pump in the future.mb_barton;775614; said:I been readin all these complicated overflow systems on the DIY section and I really dont understand why people go through sooo much effort. correct me if im wrong but If I were to buy 2 really big PVC pipes and put them vertical at the back of the tank going straight threw the bottom and into the sump, wouldnt that work perfectly fine?. i dont get this wholeuber complicated crap. I wanna keep it simple. Would this idea work?
And also does it matter if I use really big PVC pipes or small ones? because i want to make sure than those pipes can carry the necesary amount of water in case i decide in the future to have my tank cycle faster...
sometimes, though, people use the more complex drains because...
-they simply are not confident with drilling their glass tanks.
-they wanna drill but don't know how, don't have the tools, or cant find anyone they can trust to do it for them.
-they enjoy the whole D-I-Y idea and would like to see the fruit of their labor.
as long as it works, everything's ok.
