So every saltwater tank is used by distilled water?or RO/DI And what do you mean i dont need the filter?Your rock is your filter and having a filter can cause nitrates. And whats the RO/DI unit?it is a filter system that cleans your water so you don't add any bad stuff to your system.[/quote]
correct...It is a 29 gallon tank and yes i have some live rocks with 10 snails and one orange spotted goby for now. I have about 15 to 20 pounds of live rock. So i put in the tap water through the RO/DI bottles before putting it into my tank>?
