New with salt water and need help
 

I have had a 30gal. piranha tank for the past three years and I still think they are the best, now I am getting a 150gal. tank and would like to turn salty. The thing is i dont know what to do, I am looking at different places for live rock think I need about 100 pounds, would like to use a hang on the back filter and protien skimmer for overall filtration, I would like to start with a couple of snowflake morays in the tank so I am planning to bury some PVC tubing under the sand and rock for good hiding spots. I dont know anything about salt water though and would like to do as much research as I can before I get started about everything from mixing the salt, to checking the water quality on a regular basis. If anyone can give some advice it would be a great help thanks and hope to talk later.

The reference section on this forum is an amazing source of information.
Start out with the "Just Starting Out" section and go from there.
Make sure you know exactly what you want to buy before purchasing otherwise you will find yourself upgrading and wasting money.

This is a great forum with tons of ideas. Like Oxy said, you want to get it right the first time. A good lesson is to not cheap out at first thinking you will upgrade later. You won't be happy and will end up spending twice as much money in the long run.
Thats not to say you have to buy the best.There are some great bargains to be had online and through this forum but do your homework. This hobby takes time.

Spend the money on a good skimmer, you'll be thankful later on.

luckily eels are pretty hardy.
