Out of RO…what do I do?

mindiL · Jan 1, 2023

Hi folks. I have a dilemma and need advice. I have a RS Reefer 250 with a mesh lid so I have tons of evaporation. I have to fill my RO tank every 4-5 days. I usually have a good supply (bought from my LFS) but I’ve run out and my LFS is closed until tomorrow. I know I need my own RODI system at home…just haven’t gotten around to it. What can I do until I go to the LFS tomorrow? My return outlet is starting to bubble because my water is too low. HELP!

You may be able to “borrow” some from a reefer near you.

Just go buy some gallons of distilled (with no minerals added for taste) at the grocery store or Walmart.

People use distilled all the time on nanos when they don’t own a RODI. I used it for a few years myself. Not just for top off but for mixing my own salt.

Actually topped off my pico today with “Infant Water” (no fluoride kind) I had left over which is nothing more then a fancy name for distilled.

Could you reduce your turnover rate for a short while? Ie. turn the pump down and adjust the valve roughly to suit.
It won't make a big difference as everything is obviously designed for different flow rates but I certainly need more water in my system when the flow is faster.
It may buy you a few hours.

Definitely go with the distilled water.

To lower the pump or get distilled water

I generally ran to walmart or grocery store and bought water from their RO refill station

I doubt some tap water top off for a day is going to make any impact whatsoever, other than maintain your salinity.

If you have a DC return just turn the flow down. It will be fine until you can top off your ATO tomorrow.

Wish I could run to Walmart, but I live in Ireland!

Thanks! I’m going to do this and a little distilled water.

Drinking water and distilled are options

Thank for this…I was worried about using anything but RO. I’m going to see if my local shops sell distilled water. I live in Ireland and sometimes they don’t have certain things you could easily find anywhere in the US.
