I have just up-graded my garden pond from 1000 litres to approx 6500 (1717
US gal 1429 imp' gal) - 7000 litres. Is it ok to put the fish (Sarasa
comets) back in straight away? Unfortunately I could only save about 20 imp
gals of the original pond water, but hope this will help to kick start the
new pond. I have save all the plants though, including a water lily.
