Topups have to be with RO or can I use distilled water??

yip, RO is just a cheaper set up the end result is pretty much the same, double distilled is a tds of 0 i think

Yeah distilled water is fine
i have 2x 100 L drums that was filled with fresh water in 1998 and it is still siting in my store room can i use that water

That water would be pretty sterile by now as long as drums were sealed. Water would obviosly need to be aerated during saltmixing
DI is fine, different process, same result really.
Hi Matt - just an explanation - some RO units actually have a DI unit attached to it as well. Therefor: RO/DI (Reverse Osmosis/Distillation)....... I know that it is not healthy for humans to consume pure distilled water, where-as RO water is VERY healthy for humans. My RO/DI unit has split outlets - one pipe comes out before the DI unit, and the other pipe comes out of the DI unit. The DI pipe goes to my aquarium topup, and the pipe before the DI unit goes to my fridge (has a water supply built-in)....
That's cool, but there are LFS's in your area that can supply you with RO as well if you need. You don't need to drive all the way to Boksburg 9('m assuming this is what you mean't by 40km).
What is the source of your DI. To be safe just check the TDS before you use it. I would say if it is less than 10 ppm max it is good to use, although lower than this would be better (ideally 0ppm)

Jacques, the DI in and RO/DI stands for de-ionised, not distilled. Different thing completely.
AFAIK distilled water is purer than RO/DI water, but both are perfectly acceptable. Since making distilled water is much harder (more expensive) than making RO/DI water, we usually buy RO/DI units. AFAIK a lab process is required to make distilled water. The important thing is just that you want water with as much elements as possible removed, so that when you re-hydrate the salt, you only have the ions provided by the salt mixture.
Sorry Clinton - you're right - my bad.... :blushing:
I thought I was too clever again - I actually knew it - but was misguided
At last somebody agrees with me.Sims you`r my friend for life.
