Sump/fuge baffle question. Please help

FreshSaltyGuy · Oct 13, 2023

Hi all, hope someone can give me good advice cause I'm going crazy lol. I have a 75 gallon sump. I have placed the baffles you see so far the last one is an adjustable gate that I just didn't put in. So I have 1 - 14" high baffle left. I was suppose to put it after the adjustable baffle before my return pump to help with micro bubbles but when I tested the system before baffles I had zero micro bubbles. So I was thinking of putting the last baffle at the very beginning raised 3" up to have water go under right after the drains water coming in and I decided to make the fuge 1st so I was thinking if I did put the baffles raised up water would rush underneath and help spin the chaeto. Is this correct? Or should I place at end as a bubble trap?
In picture the 14" baffle is just leaned up against the last adjustable baffle.

Thank you!

The adjustable baffle is intended for some black foam that a) reduces noise and b) prevents anything larger than the pores (ie: snails) from ending up in your return pump.

In the last chamber (the one with the soup cans) you probably want less "baffle" space and more room for a return pump.
