Normally I do a partial water change about every 10 days to keep my nitrates at 0. I have 8 gallon gas cans that I go get RO water with. About 3-4 days before I plan on doing a water change I put the salt in and run a bubble wand or powerhead for 24 hrs. Well I missed the planned day to do a water change and the saltwater sat in the gas can for about 6-7 days with salt in it (after running the power head for 24 hrs) I tested it and the PH was 7.7-7.8, I put some ph up to get it up to 8.0 and put it in. Does salt water "expire" just sitting in cans....should I leave the cap on or off when waiting for my day off to do a water change? Also.....since I have a smaller tank(29 gallon) I have to top off every 3 days because the salinity goes up fast. You can add unsalted RO water right? I normally add a gallon or so over about an hours time, in front of the power head so it disperses quick. My fish don't seem to mind but they are a really hardy bunch. Thanks!
