I found a 250 watt halide for 125 and it was only used for a week.
Well I called the guy from the craigslist and told him I was interested in the light and the live sand, but I had to wait until the salt/ salinity of the tank was set. He said he would give me all the treated salt water I needed with the sand, and snails and all the other goodies? My question is, will that work? I mean if it's established water and live sand, will it be okay to put it straight into the tank?
