So in the end I didnt listen to anyone and used my pH kit to correct the pH. When I got home from work the pH was out of wack again :an!gry
What I did do was buy a kH kit and test the hardness. As suspected my water is very hard and the water the fish came in is soft. The peat managed to bring this down a bit.
The fish had to go in or die in plastic bags so I took the risk.
For now they seem to be ok I used stress coat, and stress zhyme also
I admit I was a little unprepared for the arrival. and the tank is only a temporary measure while I sort there proper one
