[Equipment] Did the H4i chamer change design?

This appears to be an H5i chamber with that 3rd piece. On my H5i tank the yellow level is part of the top.
I know what you mean by seeing that yellow level mark -- seems like I always overfill; and have to release some water from that hole in the corner.

The cleanable tank (dishwasher safe) comes in 3 parts and have stainless steel bottom
The newish standard tank comes in 2 parts and have aluminum bottom

Zonk tank made up of parts (2 parts) from both tanks, top part from the standard tank and bottom part from cleanable tank

For someone who uses tap water, that aluminum bottom is a problem. It is like the minerals stick to it like glue. I'm cleaning it much more often than I have any other tub ever. Actually, I kept my old tub and am about to go back to that one as it is now in better shape than this one.

For the H5i, which goes with the S9 series, there are 2 take apart tubs. The one that is dishwasher safe has a 3rd piece, kind of like a baffle, that fits about where the seal is along the edge. Not sure why it is there. The one that is not dishwasher safe does not have this piece.

I find that the dishwasher safe one, the yellow marker is easier to read. The print is larger and darker. The other one, I can't see it much at all. Drives me nuts.

Yes,I've alway's got the 2 pc.But,this past time I was sent the 3pc.I'm like you about the 3rd pc.I'm not complaining.All my supplies are free&cover'd thru my employer
