So I couldn't find a good answer my rodi units di filter needs changed and won't come till Monday it read at 2 I know not a lot but is it still good to use I'm finding mixed answers I have fish only(an eel and trigger) and macro algea and snails my husbands tank has coral snails and a clown and shrimp my tank needs a water change and I don't have enough to do a 15 gallon like I was planning this weekend i don't want to continue filling the jugs if it isn't good enough

First few years I kept tanks I only used RO water... My RO is around 14-18 TDS and I've used that before.

Few TDS in a water change is fine.
