Item Information

Stock Tank Secret eliminates the hassle of dumping and scrubbing slimy green, unsanitary livestock water tanks! Completely safe and chemical-free 100% organic barley straw helps keep stock tanks clean to maintain palatable drinking water. It's easy to use and lasts for up to two months.

It's a completely safe and effective treatment that contains no chemicals, pesticides or herbicides and has no toxic side effects. Commonly used by horse owners, it can be used with cattle, goats, sheep, swine, poultry, fish and even exotic animals like alpacas and llamas. It can be used in automatic waterers, larger birdbaths, ornamental ponds and fountains.

To use Stock Tank Secret, tear off the paper label and place the unopened burlap bag in tank. One bag is good for an average 200-gallon stock tank. For larger or extremely dirty tanks, use two bags. It begins working immediately, but it may take 7-10 days for you to notice its effects. Scoop out any floating debris.

  • Replace every two months
  • Burlap bag is completely biodegradable
  • Made with pride in the heartland of Nebraska, USA

Rated 5 out of 5 by from Works great We've used these for the last 3 years with great results. Its not going to magically prevent all the algae growth, but it does slow it down enough that we can extend the time between cleanings. In the height of summer we only have to dump/scrub every week or so where before we were scrubbing at least twice a week. In combo with raising the tank to allow some airflow underneath our tanks have stayed even cleaner!

Rated 5 out of 5 by from Somehow keeps water clean! Its hard to beilive how well this product works. Somehow it keeps the water very clean, no algea or other crud grows on the sides of the tank.

Still had to clean my stock tank to get out leaves and dirt that had blown in.....but not a spec of mold, algae or anything of that nature. I'm really impressed.

Rated 4 out of 5 by from Seems to work I was skeptical, but thought why not try it. It has worked very well in a 100 gal galvanized tank. I placed a rock on top of the bag to hold it down, and the water has remained clear.

Rated 1 out of 5 by from Doesn't work Had 2 of these in a bigger tank and 1 in a smaller and neither worked at all. The TS employees swore up and down that it worked, but I saw no change.

Rated 5 out of 5 by from big tanks and small I use 3 of these bags in the 300 gallon galvenized water tank for cows and 1 bag in a 100 gallon rubber tank for the horses. They work very well in both tanks

Rated 1 out of 5 by from Grows algae! Put it in a 75 gallon stick tank after scrubbing completely clean. It did the complete opposite of keeping it a bay. It in fact grew more and used the bag to grow on. We lifted it up out if he water and there were 6" slim strings I guess you'd call them. It used the bag to hang onto and grew length wise not just on the sides but more was floating around.

Rated 1 out of 5 by from HORRIBLE!! Less than 2 weeks water turned brown. I bought one of these for each of my 100 gallon stock tanks and it turned the water in both tanks a nasty murky brown in about 1.5 weeks. MUCH worse than nothing and the water has never turned that color before. I took them out of the tanks and will never use them again. Horses would not drink that brown water!!!

Rated 5 out of 5 by from Clean Water! I bought this Barley Straw in 2016 for my 100 gallon horse trough. It worked very well and for most of the summer season. I am disappointed that my local TSC doesn't have it in stock even though the website says it does. TSC, please keep this in stock in Stevensville, MI store! Thanks!

Rated 4 out of 5 by from Worked for me I put this in a concrete fountain with fish. It took a week or so to start working but the water is clear now most algae is gone. Went to TRC to get another bag and they were out even though web site said it was in stock :(

Rated 5 out of 5 by from barley straw very good for fish ponds.Safe will not kill snails,or crawdads.

Rated 4 out of 5 by from Does its job pretty well Works for about 5 weeks or so just like the directions say. A great more-natural way (vs tablets) to keep the tank clean and for a decent price.

Rated 5 out of 5 by from Highly recommend this! We have used this twice in the past year and its time again. We use it in our 100 gallon Rubbermaid tank we have set up as an environment in our home for three large red-eared slider turtles. This product truly works to keep the odor at a minimum for a long, long time.

Rated 1 out of 5 by from STOCK TANK SECRET It did not work for me. The white tablets that TSC did carry but quit carrying worked MUCH better for me. With the Barley Straw Treatment , the water was stinking and nasty after one day. The cows would not drink out of that tub.

Rated 1 out of 5 by from Didn't work for me I bought this based on other reviews, but it didn't work at all for me. I had a new stock tank (had been using it for just a couple of weeks) and decided to use this to keep it clean. The water was crystal clear when I added it (and had been for several days) but this turned the water very brown. I thought maybe it was just because barley chaff was rinsing out on the first use. My horses weren't drinking as much as usual, so I dumped the tank, cleaned it, hosed off the barley straw bag and tried again. The water stayed clear longer this time, but after it rained and agitated the water it turned brown again. And again my horses stopped drinking as much. I left it in to see what would happen ... in just a few days the water was green with algae. The bag itself was covered in green slime. I threw it out and started over without it. The horses are now drinking their normal quantities again. I wonder if climate and water temp have anything to do with the performance of the product?

Rated 5 out of 5 by from Amazed I was amazed at how quickly my horses water cleared up, stays crystal clear no signs of algae. AMAZED

Rated 5 out of 5 by from Simply Clean Water Can't find an easier way to keep your water tanks cleaner! Less algae, less slime, fewer dump and cleans! Been around for decades used in Britain and Ireland....so strange that it's hardly known about here. Hopefully this will help and Tractor Supply, please don't stop carrying this product!

Rated 5 out of 5 by from JUST SIMPLY SUPERB WATER CLEARER This stockman's secret barley stuff in its little burlap bag is a WONDERFUL natural product that really works overtime to keep stock water clearer. I use it months longer than the advert recommends and it continually helps me keep the water changes down to a minimum. My horses love the taste, too. A briliant product at an excellent price--THANK YOU Tractor Supply!!!!

I have a wildlife rainwater guzzler consisting of two 55 gallon plastic storage drums (shaded) feeding a 10 gallon trough. Given that the bag is rated for 200 gallons, would I to need split the bag up and place in each drum - or trough?

Asked by: StevenL
You do not need to split the bag, it can go in one of the tanks or in the trough. If it goes in the trough you will have to weight it.
