Storing Ro and mixed water

prosnow · #1 03-17-2006, 02:15 PM

i Have 2 100 gallon holding tanks for my ro/mixed water, would ro water be fine if i just had a big airstone in there? and would it be alright to keep saltwater mixed up in a seperate tank, keeping it heated and with an airstone or powerhead going??? yes the tanks are foodsafe used them on my freshwater systems for autotop ups and what not, and they both have lids...

thanks!

Yep, no problem keeping one with RO water, and one with mixed saltwater. Just keep the lids on so you dont get crap in there, or lose it to evaporation.

We have RO/DI water stored for about a week. During that time, it is heated and aerated with a big powerhead in a covered plastic trashcan. We salt the water the day before water changes and use it within 24 hours. We've noticed salted water kept longer than 36 hours to begin leaving a whitish ring around the water line, which I believe is something precipitating out of the saltwater.

Heating and aerating while we're waiting for the next water change gives us the opportunity to salt it and use it right away in case we need to do an emergency water change. Got to admit we haven't have many such emergencies, but having the water heated to tank temps and fully aerated has been a blessing when we have needed it.

What salt are you using and what garbage can, foodgrade brute?

Rubbermaid can, not food grade. Whitish ring has appeared with both IO and Kent salts.

I have 2 Rubbermaid Brute food safe trash cans, one for top up water and the other mixed for water changes. The mixed has a powerhead, heater and airstone and I use Kents salt. I also have lids on both to keep out crap and light.

I have had no problems with keeping the mixed for 3 or 4 weeks. The only problem I had was when I used Oceanic salt, I started to get a brown slime.
