The "housing" is new....I replaced it ~2005. The "body" of the new one cracked. I still had the original and swapped out the "new" column/body part for the original. The actual part that is in-line was replaced about '05 or so.

The "foam" in the top picture is from the SWCG when I run it higher. It definitely makes an abundance of bubbles. I have not been using it as of late per the advice on this forum.

I'm keeping the pump off tonight to see if anything will settle out of the water.

The water is much better than what you see in that picture. It is more of a whitish/blue tint now, not green BTW.
