Ok so I had a job interview the other day at a local fish store and they only do saltwater tanks they did like my enthusiasm and love for fish and I may get hired on around the end of July. They want me to set up a small saltwater tank tho so I can at least get a feel for them and etc. Well I wanna set one up real quick to marrow while a lfs near me is still having a sale on live rock $3 a pound, I have the tank heater and a 30gallon filter that I figure should provide enough flow and filtration for now until I can save up from a couple pay checks to buy a skimmer and a power head or 2. My biggest question is about sand, Will I be fine with just live rock and obviously saltwater to start, or should I buy sand tomorrow and just get a smaller amount of salt? I only have roughly 60 this pay day to work with and then next Thursday well see what I have to work with then. I do know I eventually want a deep sand bed but that will be a couple pay check away project.
