I run a reef. I use ro/di. My filter is starting to need changing: the TDS meter shows the output as 2. [That's Total Dissolved Solids] from a filter that's a little over a year old.
Well, I had to go on the road for 9 days, and didn't have time to go to the lfs and get the filter cylinders and do the change before I went.
I used the last batch of ro/di water I'd run, with the very slightly elevated TDS...in a 32 gallon topoff bucket...and went away. So my tank was automatically topping-off from slightly TDS'ed ro/di for 9 days.
I left a pristine, white sugar-sand, clean glass tank.
I came back to the tank from "Finding Nemo"...green crud, purple crud, red crud, and filmed glass and crudded sand in which a little caulerpa growth befouling one rock had become 9 inch strands threatening my corals.
I ran 16 g of saltwater from that ro/di filter. You think I'm going to use it? NO. I'll pitch it with its pricey salt rather than have that in my tank. Wednesday when the lfs opens, I'm going to be in there getting my filters replaced. Bet your sandy bottom I am.
