Ummm... please don't tell me I got ripped off by my LFS
with the wet/dry TOO. (See my post about the protein skimmer.)
This is the wet/dry that came with the tank:
I have the one on the left.
I've taken out the sponge to give me more room for the protein skimmer, pumps, and heater.
Anyway, when water evaporates from the wet/dry it evaporates water from the entire wet/dry (not just the other side w/out bioballs).
