algae in metal stock tank

[Robert D Bard]

Normally corn meal will kill algae in ponds and then becomes fish food.
I don't know what golden algae is but I would try corn meal before the greenish stuff that probably has copper sulfate. That stuff never leaves Lord know what it does to the fish and envirnmrnt.

Thank you for the reply. I will discuss the cornmeal at the TSA meeting tomorrow night. :lol:

I know this is a fairly old conversation, but I couldn't help putting in my two cents worth. I have been looking into building a koi pond in my yard and some of the info that I have learned may help you out. The gravel filter is a good idea, but I have an improvement over just regular gravel. Use large pieces of lava rock. The lava rock is very porous, and the holes make great dwellings for the microorganisms that will help clean your water. There are some pond companies near my area that are selling systems using lava rock as "biofilters" to keep koi ponds clean. All they are doing is filling a mesh bag with the lava rocks, and placing it in a reservoir that the pump empties into.

Another bit of advice I would give you is to limit the sunshine that hits the water. If there is any way you can provide full shade over the tank, it will help immensely.

I don't know if there are any native water plants that cattle will not eat, but the plants would take nutrients out of the water that the algae must have to grow. Water hyacinths are illegal to transport and use, but they are an example of the type plant that I'm thinking of. I bet the cattle would love them, too. There may be a plant that is comparable but legal to use.

Best of luck and let us know how it works out,

There is a non-toxic algaecide for use in livestock watering troughs. It's call "Krystal Trough". Read about it at www.krystaltrough.com Hope this helps! :D

I use and some of my customers use barley pellets and gold fish in my water tanks to control the algae.
