    hello, i am wanting to start a 20 gallon fowlr tank and i need to know what do i need.but i do not want to put 20 pounds of rock i want to use 5-8.
    i previously had a freshwater tank
    i have now a 20 gallon filter
    -100 watt heater
    - airpump with airstones
    - and gravel
    so what do i need and what do i replace?

    The airpump will be unnecessary.

    I've never heard of people using gravel in saltwater tanks. Most people use pool filter sand or arragonite.

    As for live rock, i promise you it will be a thousand times simpler if you just have the 20 pounds. 5-8 lbs will be essentially usless in a dencently stocked tank.

    I agree that is the best info you can have to start a saltwater tank. That thread has all the basic info and is very clear cut :)
