it makes no sense to use 1/2 & 1/2.only when cycling a tank.100% ro/di all the way.

from my understanding Ro and DI are not the same. Close but not the same. Reverse Osmosis water is 98 to 99.9 % pure. DI or de ionized water is 100% I used to work in a place with water treatment and a lab. we had both a ro unit and a di unit. there were some test that RO water was not pure enough. RO is great. Make sure that if you have a ro unit that you have a softener as well. The chlorine in the water kills the membranes in the RO unit really fast. Some city water is close to soft already. Soft water has the calcium , magnesium, annd sodium ions removed. Then usually it goes through some typee of filter( sand or a yarn type to reduce particulants. Then it would go through a type of carbon filter to remove the rest of the chlorine and iodine form the water before enteringthe RO membrane. I used to work on a unit that produced over 20000 gal of RO a day. For rinsing parts ect. Hope this helps a little.

no you do not need di. just be sure to use plastic line for your ro water. the ro water has been stripped of everything and will absorb copper if you use copper line and create pin holes in your line. should be pretty easy. If you live in the city it should be ok. your ro unit should come witha couple different filters that go before teh actual RO membrane. These will take out the chlorine and particulants before getting to the RO membrane. RO should be all you ever need. It is usually 99% pure. you should actually be able to put electricity in ro water and nothing happen becuse there isnt any ions in the water to carry the electrical charge. ( We actually did this in a college class I had). The only time I have seen it where RO was not pure enough was in a lab where the DI water was to be sure they didnt get a false reading. You should be all set. Sorry for the confusion.

fresh water requires the elements your stripping out of the water, with marine your salt mix contains what you need with fresh you have to add the required elements if you use pure ro. I myself use an RO/di unit. most ro units can be purchased with a DI cartrige if you bought one with out it you can buy an add on that will attach to your ro unit.

Good to know, I'll have to check that out!

Actually after taking to a LFS that I go to a lot , he told be to use RO Rite to the RO water and then mix my salt in . After talking to him I am on the other side of the spectrum as my water is softer than most . With using RO Rite my ph , KH , Calcium , Phosphate , and etc. are exactly where they should be . RO gets the water 99% pure and DI takes it to 100% . All the major LFS and Reef specialty stores in my area don`t use DI and say it`s not needed .

ro rite is for freshwater use.
you use it to simulate river water for freshwater tanks that you use ro water on. As I mentioned above fresh water needs ceartain elements just like marine.
your salt has everything you need for using ro/di water with out spending money on ro rite. by dosing with ro rite before hand you risk pushing you cal, kh and some other factors over the top throwing your whole system into chaos.

here is a write up on it.
Specially formulated mixture of dissolvable solids (also called general hardness or GH) which includes major salts of sodium, magnesium, calcium, and potassium together with all necessary minor and trace minerals, together with a small amount of carbonate alkalinity (KH) to reproduce artificial river water (most aquarium fish are river fish). Provides natural water chemistry for the conversion of reverse osmosis, distilled or deionized water for fresh water fish and plants. Provides a balanced electrolyte system. Useful for all fresh water fish, including Discus. This is the premium dry formula used the world over to raise discus and other freshwater species. Contains no phosphates, nitrates, silicates or organic chemicals to pollute the system! R/O RIGHT is unmatched for quality and value!
