This is how I started it this hobby
Fifteen years ago I got my first tax refund check. Being young and dumb with a little money in my pocket and already had my car fixed up I needed a new hobby. While driving down the Blvd with a girlfriend at the time she saw a painted picture of a clown fish on a window of a pet shop and conviced me to stop. We go in and look around. We get to the salt water selection and she sees the clown fish and feel in love and begged me to get her some.
Never owning an aquarium before I asked the owner what do I have to do to care for a saltwater. This is what he told me. Buy an aquarium from me and I'll give u good deal on every ting u need. Yea he was asain. Sense I had the money I was like ok. So he tells me to pick any aquarium. My girlfriend picks a 30 gallon hex. The owner tells me I need to buy a bag of salt, a bag of live sand, a bottle of cycle, a hydrometer, and an emperor hang on the back filter. Tells me to go home to fill the tank with tap water from the hose put the sand and filter in the tank. Mix the salt in to the water so that the salinity is right. Then put the directed amount of cycle in the tank and come back tomorrow to buy fish. So I did what he directed. Went back the next day and bought 2 clown fish an anemone and a blue hippo tang. Needless to say they all died with in a week.
After they all died I went back to the shop and asked the owner what happened. He says "some times it happens, want to buy more fish?" I ended up buying books instead of fish. I did a little reading and found out about filters like skimmers, live rock, medias. Also how important lights are, as well as testing ur waters parameters. I also found out what a tank cycle is.
Lets just say I have never been back to that pet shop sense.
Thanks for letting me share my noob story
