last time i had discus my water district, water was chlorine -free. now i need to remove chlorine from the water. to use seachem prime, is it safe to add it to my aged water the day before i use the aged water?

I use safe and I dose my tank before doing a w/c. i believe there are some issues with dosing the aged water a day before. The more experienced folks can chime in on those issues. also, prime and safe are instantaneous dechlorinates. No need to wait once the water is dosed. -
If you're just trying to take care of Chlorine and not Chloramine, aging your water for a day with aeration and agitation should off-gas any Chlorine in your water supply. If you have Chloramine, you will need to use some form of dechlorinator (e.g. prime). In that case you can either dose the tank right before adding the new water in or dose your aging barrel a few minutes before adding it to the tank.JakeComment

I think it's fairly common for water companies to switch between chlorine and chloramine seasonally. I believe this happened to me the first spring I had my discus. I had been getting way forgetting to add prime or adding it late and not having an issue. Until one day when it almost killed all my fish. I always added the Prime right to the tank just before I started pumping the aged water back in. I think if you add it to the barrels, your barrels are going to get slimy.Comment

I add it directly to the tank. I leave straight tap in the holding barrels to help keep them sanitized. They will get slimy over time, but a lot quicker if you add prime to the barrels.Comment

If I understand Prime correctly, it removes chlorine permanently but binds the ammonia temporarily (24-48 hours). So if you are just using it as a dechrloniator (and if my understanding is correct) it should be fine to add early.
Personally I add it directly to the tank while filling it up with tap water. Never had any issues, but I am extremely lucky to have incredibly good local water.Comment
