I've just done a 30l water change on a 110 l tank and forgot to add dechlorinator. It was about an hour before I realised. i have taken some tank water out and added the dechlorinator to that to dilute it and then put it in the tank.
. Can't believe I did that!. I was trying to do several things at once like feed the children and tidy the house and got distracted.
So am I likely to have damaged the fish?( 7 small Platys) or killed off my bacteria?
Should I take some media from my other tank to help?
Has anyone else done this and what effect did it have?
Any advice please?!.
Thankyou
