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.
wellcome to fishlore. It seems that you need more info. I recommend one thread https://www.fishlore.com/fishforum/...-starting-saltwater-tank-beginners-guide.html That's very useful for me. I am a beginner too.
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
