Tube - The Original Aqua Bag - Water Weight Bag 70 lbs - Adjustable Workout Sand Bags Weights Alternative - Portable Sandbag Fitness Equipment Set for Home Exercise Gym- Including App Videos

Great product and exercise tool to stabilize and strengthen you core as all the other reviews state. The only thing I would highly recommend is to use WAY more vinegar than what the Tidal Tank company recommends. I used a whole gallon of distilled white vinegar for the 70 lbs. bag and the rest with water to fill it half way. I also have the 30 lbs. and 50 lbs. bags and I placed about the same ratio of vinegar to water in each. I've had the bags for almost two years and NO fungus or algae growth in any of the bags and never swapped out the water and the bags are good as when I bought them. Enjoy your workouts!

Great alternative of a product. Forces you to use a lot more core stability muscles that you don’t get in traditional workouts.

First off, great product. I've used it for a few months and love it. Recently, the past month or so I didn't touch it much, I'll admit. My first mistake was filling it with outside hose water, which led to the growth of a strange bacterial film over time (I'll always fill it with cold tap water from the bath from now on). Over a month's time I noticed that the inside became coated with a nasty brown mildew. I read some reviews on here for help and couldn't find anything, and noticed that some people had tossed their tidal tank after having said problem. Here is my solution that worked 100% for me, after contemplating the same whether I should throw it out:▲[You'll need: White vinegar, Borax powder, a small bottle of isopropyl alcohol, and a bunch of salt]• First, empty the tank out into the tub drain, careful not to let it splash on surfaces, or spray you in the face while opening the valve under pressure like I did... You can wear a face mask and goggles for safety if needed since you're dealing with mildew mold spores (I didn't take my own advice). But you don't want to breathe this stuff in. If the water pools up in the tub, make sure to wash surfaces thoroughly afterwards. You could also just empty it outside.• Next, fill the tank a bit with some warm water to loosen the mildew. You can use some white vinegar here. Slosh it around and leave sitting for about 20 minutes with the air totally pressed out of it for surface coverage. This will dissolve the first layer, and trust me liquid alone isn't enough to remove the sticky, well-attached mold. Empty the tank and give it a quick flush before the next step.• After a lot of trial and error and searching I found that Borax is the supreme mold killer. I soaked my tank in the same way as the vinegar, with a few cups of borax powder and a little over a gallon of water. You can pre mix it in a cup and keep diluting it till it's all in the tank, as it takes a bit to dissolve (I left that sitting for a day or two but you don't have to do that, since the next step will totally clean the remaining mold.) You can leave the borax water sitting for about 2 hours, deflate the tank to have all surfaces covered. In my case it stripped most of the mold, but we want to destroy the last of it so it can't grow back. Rinse the tank once more.• Last you want to empty about half a container of salt into a mixing cup or water bottle, then pour half your small isopropyl alcohol bottle in with it to create a slush. Make sure you've gotten as much of the water out of the tidal tank as possible, since salt is water soluble and we don't need it to dissolve. The salt will stay granular in the alcohol which is why you should use that. We want an abrasive liquid inside the tidal tank since there's literally no way to get anything inside to scrape away the mold otherwise.• Now pour the salt and alcohol into the tidal tank, and use the remaining alcohol to wash any salt out of your cup and just in case the valve clogs up with salt. Once it's all inside, insert the pump and inflate the tidal tank fully. Now take the tank outside and get a workout violently shaking it to use the motion + the abrasive to scrape away the rest of the mold. You'll be able to clearly see any spots you missed, and the liquid will turn brown.- That's it! Just rinse it out and your tank is as good as new. For good measure I put a half cup of borax into the tank when I fill it, since it raises the pH and helps prevent mildew growth. I also change the water out weekly now, lesson learned. Hopefully this helps and you won't need to throw your tidal tank away!

Excellent for stabilization exercises for athletes who require them, especially pitchers.

I bought these for my husband on a combat zone deployment. They had minimal workout equipment available- his TRX gave him some variety but was getting dull to him only having that after a couple months. I had started using the Bosu Surge Storm recently and started searching for a similar, travel friendly version when I found Tidal Tank.Shipped to an APO with no issues, arriving mid-January. While I haven't used it myself, my husband says it's a great workout. Knowing how hard the infantry guys are on their gear plus conditions in the region- shows how durable these Tidal Tanks are. Hoping it makes it back home with him so he'll have it for many deployments to come (if not, we'll definitely buy again).Highly recommend for a solid, engaging workout traveling.
