I have a few questions for those with experience as this is my first sump design.
1) Baffle A - Most designs I've seen have this baffle at the same height as the first baffle. This creates a waterfall into the return section where the water level will be maintained by tunze lower than the skimmer section and potential bubbles. Should I remove the red section to make it lower than the water line or does it matter?
2) Baffle B - Is it needed to prevent bubbles from the waterfall due to the fuge level being higher?
3) Baffle C - Should the height of this baffle be higher than the back siphon from pumps off to prevent water in sump from entering fuge or does it matter?
