I need a few opinions on how many baffles each section gets. I have been told 2 by some and three by some. I have the first one in and getting ready to put the second one for each section. need to know if i need to add a third.
Yep, that's an overflow drain chamber which is part of the skimmer chamber which helps in the initial influx of water and the bubbles created therein...
But different than "baffles"...
