does anyone know any chemicals that affect the growth of algae in any way?

Question

if it's a chemical that slows/increases the rate of growth of algae, pls tell me the name, & incl. the site where you found out abt it under 'sources'! thanks. (:

the algae's growing in a fountain!!

Answer 1

Chlorine does a good job - often in the form sodium hypochlorite (bleach).

Look at the web for swimming pool chemicals. You'll find lots of ideas and names.

Answer 2

Algae respond to chemicals because many of them derive nutrients from chemicals. Phosphates and nitrates are particularly impt in making algae grow. To control or hinder algal growth you got to tone down on these chemicals, control their contact with such chemicals. Your fountain is apparently outdoors so it gets a lot of sunlight which makes algae grow fast. For clamping down on growth you can use algicides that are specific for them, but this might be lethal to birds and other wildlife. While chemicals are the easiest to apply they may have adverse effects on the innocent wildlife. If you want to prevent this, you can employ a more tedious step: clean the fountain regularly, by scraping the algae off the surfaces, draining the fountain, letting it dry for several days interval so as to kill algal spores. Bird poop by the way can promote algal growth. You might want to release some fish to the fountain to try to control algae which are fed on by the fish. Sorry I can't recommend chemicals because they are hazardous to the environment.

Answer 3

Algae responds to heat and phosphates since it is a primitive life form. If you have just a tabletop Budda fountain, a few drops of bleach may be all you need. Otherwise, try the web site below for effective yet safe treatments.

Answer 4

I have always used Bionetix Aquaclean (www.bionetix.co.uk). Its a bacteria and takes a about 2 weeks go remove the algae. Its worth looking at some chemical treatments, they can have long term effects on your pond.

Answer 5

There are many algicides on the market for pools, ponds, cooling towers, aquariums and fountains. My favorite in my Koi ponds is 'barley straw', it kills the algae but doesn't hurt birds, wildlife or pets. I'm not sure of the active compound.

Answer 6

Chlorine

Answer 7

Since alga are green plants, they would respond to fertilizers. Also they would respond to herbicides. I think copper sulfate is a "popular" herbicide.
