RO water storage

I am starting a 40 gallon reef and I am trying to set up my RO DI.

I want to make say 20 gallons of RO DI water, treat if with Kalk wasser and keep it circulating for as long as it lasts, I assume a month or so.

Is it OK to keep the prepared water in a covered garbage can with a power head circulating the mixed water for 4 to 6 weeks.

Is there a better method ?

Thanks

I am unsure if keeping it that long is advisable. I have never done this, so I don't know but I think bacteria would do something unless you kept it completely air free, which would cause other issues. Why do you want to store it for so long?

 

I understand that you can store ro/di for as long as ya want. They do in the stores. Just keep an air tight lid on it. As for storing it with kalk, I've no idea sorry.

 

sorry for jacking...
quick question? are you allowed to mix kalk with fresh RO water...
why how and whats its purpose.....

 

No idea here. Def not something I would do. Nor have I heard of others doing it. ??

 

My Kent Buffer says to mix it with Freshwater and then add it to the tank.

I believe this may be the directions if your using an ATO(auto top off) setup. Your talking about storing the water for up to a month. Hopefully someone with more knowledge will chime in soon.

 

is the water evporating fast? cause i use water jugs to keep my ro/di water for topoffs till i get an ATO. but it has to be a water jug.

 

I use old milk jugs to store my water in and I have some kalkwater in one of them that I store and have stored for... 4-5 months now. I just shake it up to get an even solution since it does settle on the bottom of the jug but thats me.
