General levels and RO/DI ?

[formanbob]

So I got my RO/DI unit and it is working grate but is brings up more questions,,,


I have a 90g FW NO cillids/planted, and a 30g SW FOWLR and small reef.

I have been told that I need to add stuff to my water now.


In a two part answer one for the fresh one for the SW what about the following questions.

What do I need to add that the RO/DI is removing, what should I be adding anyway. Should I get a master test kit, what other test do I need to get, what should my levels be at. Such as ( temp, salinity, ph, calcium, etc)


Thanks

for SW just your salt should give you the necessary elements. For FW I do not know.

For saltwater you need to add nothing. If you want to mix the RO water with Kalk as a calcium supplment when you do your top offs thats fine. The only thing you need to add is salt mix and thats only when your adding water after a water change. For the FW tanks you might need to add something to boost the PH since RO water will have a nutural PH.

what are the "necessary elements"

 

[malkore]

mostly things that contribute to water hardness - calcium carbonate, magnesium...stuff you'd find in any commercial RO buffer product.

Sorry, hadn't made a spelling comment in a while, don't want people to think I don't watch.
