I have no idea where to post this question so . . . What are your best tips for controlling algae in stock tanks & livestock fountains? We used to use carp, which amazingly worked well, but the only place in town we could get them went out of business (naturally). Has anyone used Stock Tank Defense? More importantly, does it actually work? We down-sized from a 600 to a 300 gal stock tank in one of the pastures, mainly because there's a decent pond & the tank was too big for the de icer to effectively work in the winter, plus we only keep avg 8 heifers & a bull in that pasture. Manually cleaning the fountain (Ritchie) at the barn isn't a big deal - but it's not fun. Thoughts? Go!

I use goldfish in mine. A goldfish is a type of carp, and you can get them at any pet store. You can get small ones for less than 50 cents at the chain stores. They also eat mosquito larvae, which is an extra bonus.
 
Copper sulfate works well. Some companies mold it into a small ball and sell it as "Blue Stone" in a jar. Check with your feed store next time you go in.

I tried using fish years ago. Couldn;t figure out why the disappeared until one day I saw a family of coons perched on the tank and fishing. I would put in a half dozen and it would take them a bout month to empty it.

granular form cutrine.
In ponds I just broadcast granular copper sulfate. A lot cheaper then cutrine
I wonder if just changing the PH would help. I know that gypsum spread in a pond will change the PH enough that cloudy water from suspended clay will clear. When a new pond is filling that's one of the first things I do.
 
I put a half ounce of bleach in a 300 gallon tank when algae starts to come to life. Stock defense never worked that great for me. The bleach concentration is less than recommended dose for water purification, but does a nice job of knocking down algae.
 
I used to have an old galvanized tank with goldfish in it but I had to remove them because the goldfish kept pecking the algae and stuff off the walls of the tanks but this stuff was the only thing keeping the waster from running out of the many holes in the side of the tank.

Now that's funny. I mean, I'm sorry for the hassle but . . . :)

Bleach is something I always have on hand. And I'm not concerned with water purification, seeing as how they use the pond as their toilet. (Why do they do that?!?)
 
We buy the tablets that go in the pool filters, about the size of a quarter, chlorine. Drop a few in the water when we notice it getting nasty. Works great, and when we go to fairs the cattle do not have a problem drinking the city water since it smells like chlorine.
 
I have county water for the house, well water for the cattle. I can hook the county water up easy if the well was to go out and for a long time I used the county water till I was using so much I could afford the well. Anyway when using the county water there's no algae in the tanks. Soon as we change to well water they start growing. Sometime I might, if I really run out of things to do, change over for a week or so and let the tanks clear up.
My cattle never showed a preference as to which one they drank though.

Was the tank that old or full of bullet holes? Because someone (hopefully just stupid kids) actually shot all our stock tanks a couple years ago during the drought. I always have an extra tube of Bondo on hand.
 
We only have well water unless there's a drought, in which case we pump/haul from our watershed lake. I did add bleach this afternoon & will see how that works but my to-do list for tomorrow consists of checking the local Coop's to see if they have or can order copper sulfate/Blue Stone, search for small chlorinated pool tablets & visit the pet store for Goldfish. A huge THANK YOU to everyone!
