how long does it take Prime to work?
As I'm setting up a planted Discus tank here in the UK I would like to ask how long it takes for Prime to "fix" my new water which I have in a 5gallon container ready to go back in the tank.
I am keen that no chlorine or simialr nasty gets into the tank and reaches the bilogial filter medium.
When I do a water change should I dose with Prime for whole tank or just the amount of new water going in?
Should I add my Flourish and Excel some time after the new water has been introduced into the tank?
It is a new 55gal tank with fine gravel andLaterite as the base, 80w of light with reflectors.
