Yes I believe it can if some kind of organic matter has been introduced to the tanks environment. Organic matter that would ferment in water. Just a thought, or have you put any new rocks or gravel in lately without washing them first?

This from the University of Missouri Extension Service:
Stock Watering Tanks

Chlorine Bleach
Add 2-3 ounces of 5.25% sodium hypochlorite (unscented laundry bleach) per 100 gallons of tank capacity every week. The chlorine will dissipate more rapidly in hot weather or if organic material is present in the tank. Do not use pipeline sanitizer or swimming pool chlorine. To determine gallonage of a square or rectangular tank, multiply in feet: (length x width x depth x 7.5). To estimate gallonage of a round tank, multiply in feet: (diameter x diameter x depth x 6).

Copper Sulfate
Add copper sulphate (Bluestone or Blue Vitrol) at the rate of 1/8 teaspoon per 100 gallons of water to kill existing algae. It should then be mechanically removed. Cover or shade the tanks to help slow algae growth.

Zinc Sulfate
Dissolve one cup of zinc sulfate in one gallon of warm water and put 1/2 cup of this solution per 100 gallons of water in tanks as often as necessary (it will depend on number of animals drinking, amount of organic material in trough, and weather). Or if bird manure on the roof is not a factor, direct runoff from galvanized roofs into waterers.

I did not make myself clear.What I am wanting to do is grow algae,but no bloom.I have done some different gardening.I have grown the biggest and most sweet potatoes than I have ever seen.I used bricklayer sand that was green from algae.The algae is very high in phosphorus just what potatoes love.So that is the test we will see if it works on Irish potatoes.

I still don't understand, jackman, are you growing hydroponic veggies? I don't see how potatoes (one of my favourite foods) can be grown hydroponically ? Can't even assume how you are growing these ? Can you show us a picture ?

I would be glad to show you pictures,if you tell me how to download on this site.I will tell you how they were grown.I have 16 tires with one sidewall cutout.I put the algae sand in each tire with some compost.The algae sand was from my pool water filter that had only Baqucil to keep it clear.(no bleach) It was one of these things you try.I had no idea it was a potato food.
