Sean,
Yes...what Gabriel said and showed.
I am only using the little 25mg model (got it in a frag trade at the lfs) and have found that using low levels of 03 actually enhances skimmate production. I tried using 50mg per Eheim on my 902 and it didn't produce ANY skimmate for the 2 days it was hooked up!
After reading a thread started by explorer364 in the Deltec forum, I decided to try the low level 03 method. He was injecting low levels of 03 into the input of his skimmer via a Venturi with great results.
The orp in my reef has always been high, so using a small Sander gives me more peace of mind that I won't overdose.
The rheostat on my Sander is only at the 50% mark. The crud in the skimmer cup has always been totally rank, but now it's even worse (if that's possible)!
