I just received the brs universal co2 scrubber and it has no instructions, it look like it can with three sponges but I don’t know what the third sponge is for I also do know wether to hook the skimmer line to the IN or to the OUT I assume I hook the skimmer up
To the OUT, I set it up without the third sponge but want to make sure I hooked it up right lol
