I'm looking to keep some "fresh" salt water, for topping up my zoo plankton mix.

Any ideas how long I could keep this in a sealed water bottle, with no movement etc?

Cheers,

Greg

anyone? Got some left over in a bucket at the moment, and can't decide what to do with it!

I used to make up a load of salt water for several water changes and kept it for months before using it and had no discernible adverse effects.

Don't think it would be a problem!

do not know how long it will keep without air, it maybe an idea to keep it in a un-sealed container where the top is open and use a powerhead or someting similar to airate the water and keep it moving, not sure on sealed though, water would perhaps go stale?

leaving it open whilst aerating it will surely draw all the crap of the day in and pollute the water if keeping it for lengthy periods !!!!!

When i make a batch of ro water i add the salt then keep the whole thing heated and moving to keep it aerated, you can not aerate a sealed unit as it will just build up the gases, not sure what the time period is on this and i would also be interested to hear other peopls thoughts or experiences on this.

We do this anyway with thise glass things with fish and corals in them :D

Seriously, you need to consider the container. If using plastic my main concern is what leaches out of the container in a period of time. This is an unknown factor. Just because it is food safe doesn't mean that nothing will leach. If I buy a container from supplier A it might be the same as from supplier B. No doubt someone in the plastic industry will correct me on this.

If being storied over a period of time, the safest bet IMO would be glass.

After saying all that I make up 2 months worth in a plastic food safe container storing without heating/aerating.

would this apply to freshly collected saltwater from the sea? as i collect my salt water straight out of the ocean!! so i wonder if i could keep that stored so i wouldnt have to go running to the beach each week to get water!!

yes dave i agree but the water in your tank is filtered and skimmed!!!! i'm not tryin to be a pain in the neck but i am considering doin this too save time on changes but i'd like to be 100% sure this is ok up to now i've been mixing and aerating the salt water about 24 hrs b4 a change and it would be easier to have the water pre mixed and ready to go... and yes in an ideal world having a large tank solely for water would be great but i just dont have the space for such luxury lol ...
