Hi

The water in my barrel pond where I have a water lily has got an
unpleasant oily sheen - I think it might be going stagnant. Is there a
chemical I can add to the water to get rid of this? I don't have room
for more plants to oxygenate the water so I wanted to try and find
something I could add to the water to get rid of this film.

Thanks.

Lynda,

I am prety sure that there is room for one little oxygenator.
Pet shops sell little bunches for the tiny bowls some people keep goldfish
in.
If your pond is unhealthy - not maintaining itself naturally - then blitzing
it with chemicals is not going to make it better.
If you go the 'chemicals' route you will have to repeat the treatment at
regular intervals - you are tackling the symptoms not the disease.

I would suggest that you add one small oxygenator and commit to removing any
excess growth once a month (or less frequently if the pond looks O.K.) and
adding this to your borders or compost heap.

This is likely to keep your pond much more healthy, be more environmentally
friendly, and cost less and take less efforts than repeated chemical
treatment.
