Best thing you purchased for your tank last year

For me, I gotta say books.
The Conscientious Marine Aquarist, Robert M. Fenner
Reef Invertebrates, Anthony Calfo
Aquarium Corals, Eric H. Borneman
Book of Coral Propagation, Volume 1, Anthony Calfo

Hands down, my 50 ft. python - never will be without one from now on!!!!

for me, it was 20 feet of vinyl tube, 18 feet of pvc, a garbage can, and two magdrive pumps. Put it all together and I can now pump water out and back in with the flip of a switch. This edged out a 50 ft python for top honors.

My best purchase was my 30 gal. That's the only big purchase I made :|
The 20 gal was standing in my dad's attic

For me, it was the tank itself. 8O A picture can be seen in my photo album here. Work still in progress... Working on the plumbing system presently. Slow... Slow... Slow.... Patience.... Patience... Patience.... Sigh....
