Hello Everyone,

I have a 29 gallon SW tank that has been up and running for about 7 months
now. I have 2 damsels, one common clown, 1 cleaner shrimp, an astrea
snail
and a hermit crab.

My filter is a Marineland 170 filter with biowheel. The temp stays around
77 and the specific gravity is maintained at 1.023.

I finally bought a protein skimmer over the weekend (Red Sea Prizm
Skimmer).
I was very excited to get it up and running (especially when I saw all of
the gunk it skims out of the water). I hope this means I won't have to do
those 50% water changes every single week now!

Anyway, my question is this...when I bought the skimmer at the LFS, I
asked
the guy helping me if the skimmer added any additional aeration to the
tank,
and if so could I remove my airstone. He said absolutely, but I'm nervous
and wanted a second opinion. I don't want to deprive my pets of oxygen.
Do
my filter and protein skimmer provide enough aeration to the tank, or
should
I put the airstone back in?

Any advice would be appreciated...

Thanks!

Mer
