Stupid rodi mistake, worried?

[Brandon.helvie]

Foolish mistake.... my ato ran out earlier and I refilled the container. Apparently when I was teaching my son to mix water he had done it in my container that houses my rodi.luckily it was recently cleaned but apparently still had some salt residue in it. Short story, there’s 1.005 in my ato currently and unable to make fresh water until tomorrow. Run tank at 1.026. How quickly is this going to raise salinity? Leaning toward just cutting off ato until tomorrow evening but will evaporation raise the salinity more significantly in that manner..

How big of a tan and what's the everperation rate

I mean, take out some of that high salt water and let the ATO lower salt water in. That'll lower your salinity... Am I missing something? It'll definitely get you through a few days

I'd just keep the ATO hooked up & wait till you have more RO water made. 1.005 SG top-off water is still better than no top-off water if you are evaporating any.

Sounds good. It’s a 40 with relatively low evap rate (5 gallons every 10 days or so) just happened to test the water in my ato container. Son is 9 and is making an effort to learn, not a huge deal. Sounds like nothing to be concerned about regarding raising salinity quickly. Will just make fresh water tomorrow and replace. Appreciate it.

I can't vouch for the math on this site, but it IS something that you can estimate the outcome of mathematically. It's late and I can't find my pencil or I'd attempt the math myself lol.

Appreciate it! Good god I hate math... I can cite case law all day but can’t figure out anything beyond basic math. This made it relatively easy!

I’m gonna take a shot at this for fun.
1.005 is roughly 20% of 1.026 salinity and 5gallons is 12.5% of 40 gallons this should mean once it’s empty it will raise salinity by 20% of 12.5% which is 2.5% which is .002565 which will raise it to 1.028565 almost 1.029 sg
its late and I may be crazy so feel free to correct me.
