yeah i have no problem doing the changes, I have changed over 50% of the tank today over 2 changes (i need a bigger bucket) how large should my changes be?
until your results are zero - so a 100% change would be ideal really. if not, as much as possible really, but more than 50%. Bear in mind you dont want to stress the fish out too much, so one big water change at the beginning of the wtaer treatment stage would be a good idea to get off to a positive start. Then you're going to have to test the water every day while your tank is fish-in cycling.
Is your filter suitable for the capacity of your tank?
