As I hunt for a tank setup (the wife said go 90 gallons!), I set up a pico tank similar to this

The only real cost was the live rock- which i bought WAY to much of.
I realized i can get RO water from my work in small batches and salt up myself- although i did buy a jug of premixed salt water today. All in all everything was about $100, and if i could of found my old aquarium stuff would of been much cheaper.
If anyone knows of anyone else looking to get rid of a decent 90 gallon setup for a reasonable price send me a pm!!!
