My sump has a small chamber before the pump chamber, where there is a large black foam bubble filter. I read that these can be nitrate factories so I removed it and just put in some rubble rock I had left over. Here is a shot.
Is there any harm or benefit from doing this? I thought it would help break up any bubbles coming from the skimmer.
