Where do you store your ato water
 

I stored them at a 5 gallon salt water bucket but with almost 2 gallon evaporation every day the bucket is not big enough, can u please shot me a picture of your setup? thanks

29 gallon aquarium I had sitting around.

Here's a super cheap method, Rubbermaid Tub with float valve, a hole drilled in the bottom with 1/4" poly tube feeding into a 5 gallon pail with kalk with an airline check valve so i don't run kalk into my rubbermaid tub if it's more empty than the kalk. Then gravity fed to the tank with a float valve in there. It'd behind a door, so didn't care how it looked. Works great, only issue i've had is after i moved the Kalk bucket onto the same shelf i have to restart the syphon if i let the rubbermaid tub run empty. I usually leave my RODI on since I have an auto shutoff on it, but recently i've been turning it off since I don't check on it as much as i used to and would hate for there to be an issue one day.

I wasn't running kalk for the first year so had the rubbermaid tub feed straight to the tank's float valve. Now i've been using kalk and loving it, onlt thing i hate is that i add kalk when my PH is already high during the day when i have the most evaporation. I've ordered a solenoid to shut it off during the day and just top off at night, then i should be happy as can be.

Ignore the wires on top of there, i'm changing my temp probe out and left it a mess. As the same with the 3 part pre-mix bottles :P. I really need to do some tank housekeeping....

Stored in a 33 gallon rubbermaid food save container with the float valve fed by kent ro unit with a brs auto shut off valve as the float is not meant to hold more than a few pounds of pressure. I have a 10 gallon tank as my ato tank under the sump which feeds my kalk stirrer. I top up the 10 gallon(well the wife does:redface:) every 2-3 days. I can snap some pictures for you later.

Here's mine, I use a Reefkeeper with float switches

Lol. I went a bit overkill and have 2 x 45 gallon barrels. 1 for the fresh RO and one to do my water change mixing in.

I bought a 35 gallon pail from Johnston Plastics drilled it out and set up my RO/DI unit to fill.

THe second barrel is a good idea, i do water changes in my ATO bucket, so my RO water is never really 0 TDS from the tiny bit of residual salt.

Thanks guys, the problem I am having is to having a big bucket sitting next to the DT, which brothers me a lot.

Sounds like a fish room is in order.
