Thanks for the tips - I'll investigate these options...

I have a 12000L pond with plants & NO fish. The filter/pump/UV are

'green gloopy' sounds like string algae or blanket weed. A UV can't
help with this at all, it can only help with the water born algae. Is
the water itself clear?

I'm in North Yorkshire and the weather here hasn't been warm enough to
get the plants going and I suspect you may have the same problem. The
blanket weed did start off exceptionally well this year but I used some
Nishikoi Goodbye Blanket Weed in May and that got rid of it all in a
few weeks and it hasn't returned. If you try it you should fish out the
dead weed otherwise it will just rot and start the cycle again.

I'm not a fan of the UV. I prefer plants and potash to battle algae and
we simply don't get the water born algae that a UV would be useful for.
Seeing it is a useful tool for water condition in my opinion. String
algae is always a problem until the plants get going but I will use
goodbye blanket weed in future for that.

You can get goodbye blanket weed from http://www.aquatics-online.co.uk/
select 'Ponds', then 'Pond Medicines, Cures & Water Treatments' and you
will see it listed. You might need three tubs for your size of pond but
at least that will get you free carriage :-)

Plants are really the answer but with temperatures as low as nightime
of 7 and daytime at 11 these tropical floaters don't really stand much
chance. The water hyacinth and lettuce are just hanging on waiting for
the summer.
