actually mine looks older than that. Mine doesnt have any black on it at all. It is all beige with a bunch of little bolts that hold the top cover on.


and when I say high, the psi was somewhere around 30 and I remember the previous owner saying that it should be somewhere around 15-20 i believe.

if it stays pretty warm today I will open up the filter, hose off the inside and put some more DE in it and run it.

one more question, how do i determine how much de I need?
