Dry form makes it economical and easy to store.

The seal was opened

I used the tiniest bit to cycle my small aquarium. No cloudy water at all. Good stuff.

This stuff works in my pond. Will keep buying.

Easy to use and effective when dosing instruction followed in 1200 gal koi pond

As advertised.

Cleared in a day

Very simple:1. My new 250 gal. outdoor pond w/goldfish plants quickly turned green-ish2. After adding 1/4 scoop daily for a week, the water was as clear as the tap3. Now adding that same 1/4 scoop once/week, the water stays clear4. My fish are active growing, and my plants are blossomingVery happy = Five Stars :-)

My small pond was starting to cloud up and look green. I added this and after a second dose I noticed it was so clear I could see the bottom and my goldfish. I am very pleased.

We finished building our pond around April. It is the time that the temperature goes up and algae blooms like crazy. I did a lot research and believed what happened to my new pond is called New Pond Synonym-- water is green, fish is dying. To fix this, you will need patience, some shade over your pond, and this stuff.Now, it's been a month, and the water finally beginning to get clear. It's not crystal clear yet but huge improvement. I will keep applying this stuff through out the warm season.

I have a 28 gallon pond and about less than one quarter scoop (about a pinch) made my cloudy water crystal clear. Very happy with product. And the delivery was sooner than expected.

I have a 6000 gallon pond with 20 huge Koi. Every year the trees around the pond dump thousands of leaves and flowers into the water. Then it starts to look like Tea. I put 5 scoops of this in last night and today it looks 3 shades lighter and the water looks very clear. I am hoping it will continue to lighten the water. A lot of reviews said 10-14 days. So far it seems to be working and it is a great price.Update: Ok, It's works. It has only been a week and the water is super clear. The “teaing” looks a lot lighter and most of the bottom muck is gone. It looks a lot better. I definitely put more than what it says on the label. Ponds run on bacteria so I figured can't hurt.Update 2 Ot has been a few months and I have been adding this once a week after I backwash my filter. OMG my pond has never been this clear. This is the best bacteria I've ever used and it is about a quarter of the price of all the rest.

Seemed to have no impact. Following instructions as directed.

I was skeptical that this would work, but it did. We are in Florida and have a small fish pond in our yard that was here when we moved here. There were little goldfish in it that had survived for several years on their own. We cleaned the pond out and the fish are jynormous now. We have had an issue with green water from time to time and tried multiple things. We have a pond pump with filter and good oxygen production. We have some floating lettuce and hyacinths as well as shade cloth so the fish can get out of the sun. During Spring through Summer the water turned soup green and no matter how many times we cleaned the filter, the water would not clear up. So we checked the PH. It was too acidic. So we decided it needed good bacteria to balance the PH (after a little research.) This product worked. It's not crystal clear yet but the best it's ever been for clarity. Highly recommend if you're experiencing similar issues. We have not lost any fish using this product. They are healthy and happy.

Great product, I have had issues with keeping bacteria and water consistency under control. New house and new water was making my tank brown. RO filtered water for 3 months to see if I could get it to fix. RO water changes were kinda working but after a week it would be back to crap. Got this product and on week 2 water change it was almost clear. This will last if you don't have a big pond

If you put too much the water will be a little cloudy for a while but the right amount will keep your water clear and my pond don't smell at all.I over feed my fishes because I love to feed and they love to eat. But I have no problem so far.

This is the best thing I could ever bought for my fish tank it keeps my water looking good all the time very very very happy thank you.

Working good to keep the green algae off my new bubbling Rock feature.

It's not working. I used it for two months so far and the water is not clear.
