Don't fret.

The pond is new and it could be down to the fact that the water is
originally tap water. This can be treated, byut a pond really doesn't start
looking after itself until it's about three to five years old.

We have gone through all these problems and have tried everything in the
chemical line to prevent things such as blanket weed, scum, sludge etc.

Check out www.pennix.co.uk to see the pond now and see that it is almost
looking after itself. We have grass snakes, newts, dragonfly nymphs, koi,
goldfish and comets living in it.

True, we have spent a lot of money to get it to this stage and if we had
known that it takes years for the eco-system to build up and the balance to
establish, we could have saved ourselves a fortune!

Hi, i have just started off a new pond and although the water is
crystal clear there is a green film over everything else thats in the
pond, the lights, the liner, the pumps, everything. The pond has only
had water in it for a week now and has been constantly running through
a "clearpond 25" filter, the pond contains 2300 ltrs of water and is
being pumped through the filter near to 2000 ltrs per hour, the filter
also has a built in uvc. Please could you give me any advise as to why
this is happening and how i can prevent/stop it from continuing. Many
thanks in advance for any help you can give. Simon
