I Use a product in the UK called BLANC-KIT and find it very effective
and gives about 4-5 months protection. So I only dose once a year in the
spring.

I know there are lots of products available, but can anyone recommend a
really good solution (forgive the pun)?

water hyacinths and a tablespoon of 0-0-60 per 1000 gallons every couple
of
weeks. This works even better than the alum I used for years. Jerri
