RO/DI water?

hey everyone,
ikno that using ro or di water is far more better than using tap water, I had a quick question

what would the drinking water that comes in the big jugs where you have it sitting on the unit and it pour water into your cup be considered ? (sorry for the long description lol)

Would it be RO/DI water and safe for fish?

You need to re mineralize the water with the electrolytes and whatnot in order for it to safe for freshwater fish. RO Right, Equilibrium both seem to be the answer from what I have read. Either one will supposedly work just fine.

I have a DI unit myself, though I am still learning and experimenting with parameters before using it in my tanks.

Cheers

I'm curious as to what you prefer to buffer your water with? Why do you pump air for 24 hours?

I have a DI unit and am still unsure as to how to use it properly without endangering my fish or plants. Does the use of a chem like RO right or Equilibrium suffice?

Thanks!

Depending on what your using it for. There are buffers for about every type of parameters that you want to use.

I buffer for cichlids so I use cichlid salt and malawi buffer 33 grams of salt and 140 grams of the buffer says right on the bottle how much to use for each 10 gallons the pump moves the water to dissolve the buffer ,the air stone is not needed but helps .
Cichlids like high ph 8.0-8.2 its hard to buffer di water that high, I just don't want to use the dirty tap water, my water is clean and I control all the readings

You would want to use soothing like seachem equilibrium and alkaline buffer then 24 hours latter if your ph reads high you add a little acid buffer to lower .

You want to keep you ph and temp as close as possible to match your tank.
It was a little confusing at first, it gets easier only measure no need to take test reads brcouse its always the same.
