The flowmeter is for CL02 service, no metal parts at all on it. I had a 316SS one before, but I had a rust like deposit building up on it.
Original pictures are from about 1 year ago (Maybe 10 months). I changed the media, because I did not have enough flow through it even with the MAG7. It took me 1 hour to rinse the milk out of the media, but I have not put it back it. So I guess if you don't have enough flow, it could work when the media is fresh, but later down the road it will only get worse. I had a sponge in the bottom that cause all the problems. But in 6 months, I did use 4 inches of media.
I purchased the large flanges from Titus. The seals he sent never worked to my satisfaction, so I went with the O-rings. I real fat one on the big chamber. The acrylic is 3/8" but I find the large flange should have been 1/4" to work better with my big O-ring.
Yes that is the back side of my ETSS 800 Skimmer you can see.

In the other pictures you can see the Iwaki 55RLT I use on the skimmer.
