Water change question..

[tidioute06]

I've been looking for answer to this question and i havent found anything so i figured i'd ask.
When you do a 25% water change Should you add enough stress coat for the amount you changed out or for the whole tank. I'm adding this to eliminate the chlorine and such..The bottle doesnt tell ya and i'd rather not over-dose the tank.
thanks in advance!

just the ammount you changed ( plus a little extra to be sure) if you are using buckets

entire tank if you are using a python

if you use a python and dose for the entire tank, Prime is a very reliable and concentrated dechlorinator that will save you a lot of $$.

Ever Heard of it?

Never heard of it but if it does what it says just follow the directions they give. People on here use prime because it is so concentrated it comes out cheaper to use and it works.

I also dose for the whole tank, 1 cap full of Prime { 5 ml } on the 250 ml bottle is good for 50 gallons, i use 2 cap fulls for the 80....:)
