water for new saltwater tank

[Pennies2Cents]

not good results, unless you are planning a fowler tank. But even then it is recommended that you use RO/DI water.

The Calcium levels as well as all other metals in TAP water will keep your corals from growing like you would want them too or even death. :(

Might want to do some research reading about tap water and all the components it has that may be harmful to your coral & fish.

The whole purpose of the RO/DI Unit is to remove as much if not all those things from your water to maintain a beautiful growing healthy reef.

Hope this helps.
