Hi, I'm Ann and I live in the English midlands. For years beyond measure I've kept fish, been a devoted gardener and pondkeeper and of recent years I managed a company that desilts lakes and restores aquatic environments, including river bank repairs after flooding.

What we have only just realised is that domestic pondkeepers don't seem to use a product that we use twice a year on the large lakes and village ponds that we help to care for. That's Siltex. We use it to help break down existing organic silt (the stinky black gunge) and to prevent new deposits from become blacky and stinky.

Normally we sell it by the tonne; we've just realised that we maybe should sell it by the kilo... which treats a 4x4m pond.

What do you think? Shall I put the technical info up as part of the thread?
