Most people recommend ro but alot of people use tap for the initial fill up and ro for water changes. It is very expensive for an initial fill up of ro. I use only tap for all my water on both tanks but our water is pretty good here.

Hard to calculate it because sand and rock displace water. So you need less water then the size of tank. Isn't your tank already filled and cycling?

I did this before I got my RO/DI system. Depending on how your tap water is, get ready to fight off the algae blooms. Once you get the RO, you will eventually cycle the tap water out, but it will take a while.
The RO would depend on how many GPD it will make, unless you're talking about buying RO water and adding it in. I would recommend this before adding tap water.

58 cents a gallon at wallmart. I have the same tank and it took around 40 gallons, so say 20 bucks. I used tap for initial fill, but use RO now.
