Hi,
I have been warned by a long time fish keeper that sterlets and pond
liner don't mix, apparently their fins are very sharp and can cut through
pond liner.
Although they can become very tame when young and feed from the hand, I
havent kept any for that reason, but they are lovely fish.

possible correction
Or was that sturgeon, old age it don't come by itself you know

In reply to MB ) who wrote this in
, I, Marvo, say :

I created quite a large pond last year - about 10 meters in diameter
holding a bit over 20,000 litres of water. My aim was to encourage as
much wildlife as possible into our garden, which I am pleased we seem
to have succeeded with.

I have noticed that we have accumulated a significant amount of sludge
/ blanket weed in the bottom of the pond - even after just one year.
We have no filters or water movement, as I wanted to create as
natural an environment as possible. For the same reason, I haven't
introduced fish.

Should I attempt to clear the sludge out? I am concerned that if I
leave it, over time, the amount of sludge will take over, but equally,
if I clear it, I may upset the balance of the pond. The water has
remained pretty clear, and the plants, in the main, are healthy.


Any advice would be gratefully received.

Unless you're very anti-fish, introduce a brace of sterlets into the pond
and wait. There are other pond-clearing fish but the sterlet's the best,
IMHO.
