15.01.09 72hrs after new tank set up

Here are the water test readings for 72hrs post set up in parts per million (ppm)

Amonia 0.25
Nitrite 0
Nitrate 10
pH 8.5

Not sure why nitrate is coming up here before nitrite. Maybe because this isn't really a brand-new set up as more than 50% of the water in this tank comes from the old one. Still the amonia is still in there and nitrate is coming up plus I tested the pH with the high range kit which is 8.5. Although this is high, it's not a problem in itself but amonia is more toxic to fish in the presence of high pH (see Chris Andrews et al for more on this)

Aims
To remove amonia
To reduce pH

Action
Add more good bacteria - I'm using King British Safe Water
20% water change

Water used in change
Tesco mineral water x 20ltrs
Morrisons mineral water x 5ltrs
