Setting up a large tank

[BioMan]

What size RO/DI unit do people have with 300 gal tanks? My 90 GPD looks like itll take a week to fill my tank and sump! What do the big boys do?
I want to add that I now have well water so is there anything else I should know?

You usually only fill your tank once...after that you need small amounts for top off, and 'slightly' larger amounts for water changes.
For my ~700g system, I have a 100gpd unit

I use 50 gpd for my 300 gal system when I filled it took few days

Albano, I've viewed your tank thread a few times to say the least, and you def deserve the TOTM award, but am I understanding you correctly you took over 10 days to fill it up? I guess the waste water goes back into the ground anyways, thus back into the well. Or am I misunderstanding this whole well water thing?
