  • Clear water
Size: 8-Ounce Style: Pond Treatment
My aquarium water was green and cloudy. After the first treatment. the water was clear and the filter was filled with unwanted algae. Fish are still alive too! I was worried the most about that.

  • No algae
Size: 16-Ounce Style: Pond Treatment
I have a very small decorative fountain in the garden, after a few days with squirrels and birds visiting, I'd notice green algae in the bottom of it. Got this product, put just a little bit in every time we refill, and haven't seen algae since! Keeps the fountain nice and clear, and is still safe for birdies to drink from it. ... show more

  • Works great
Size: 16-Ounce Style: Pond Treatment
This product is great and clear the algae quick, I saw the algae was sitting on my water filter where I can easily remove it. The algae was not all over the pond as it was before I used it and none of my fish died. Pond water is now clear

  • Getting rid of snails
Size: 2.5-Gallon Style: Pond Treatment
I've tried other costly products to rid my pond of snails like Anhors Away which is no longer availiable. I have 54 Koi ranging from 2' to 8" in my backyard 4k pond and use Algae Fix for my Discus 35gal Aquarium indoors at 1 drop per gallon every week afer a 5gal. water change without any side effects. Anchors Away they claim is hazardous to snails and crayfish only to have return shortly after the treatment is over. I put Algae Fix with the treament of Anchors Away and noticed the small cone shaped snails start to float to the surface dead. I thought maybe I got a strong batch of Anchors Away or the dosage was sronger since I was only adding it to my bog that holds 150 gallons compared to my pond that holds 4K. The bog cleared up and treated the pond with Achors Away so I thought it was a good chance to see if the snails were gone. Since I didn't treat the rest of the pond with Algae Fix the snals returned within two weeks. Then I decided to experiment and tried Algae Fix by itself since I could no longer get Anchors Away. Using the instructions on the Algae Fix container I started to notice that the snail count was coming down. Within a week I only saw one snail in the vortex filter I used on my two bottom drains coming in from the 4K pond. Then about the following week I noticed a large adult snail so I decided to continue a three week treatment, after that I used Algae Fix here and there. I've gone about a month with no Algae Fix additions and no sign of snails. My pond was snail free until put some plants that come with snails in them, thinking that a few snails might be good for the pond. That was till they over populated my filter tanks, and I read that dead snails were toxic to my water column. This product is unsurpassed in killing algae, string algae as well as algae bloom. You may see some brown water that is due to dead algea that must be removed and 10% water change is suggested. My pond is direct sunlight so getting algae to grow is no problem. I do believe there should be algae on the sides of the pond but I hate to see green water. Be sure to have STRONG AERATION with air stones, since dying algae comsumes lots of oxygen, watch fish to see if they are gasping for air at the surface of pond this is a strong indication the water is lacking sufficent oxygen in water becareful follow instructions. ... show more

  • Controls algae. Didn't risk it with my fish.
Size: 16-Ounce Style: Pond Treatment
After reading through the reviews, I didn't want to risk killing any of my fish. If that weren't a concern the stuff would get 5 stars. Having fought nuisance hair algae for decades, this stuff works great... 'Been treating just the quarantine tank ( NO fish) for about a week and it's doing a good job on all of the algae types. The hair algae is putting up a strong fight, but Algaefix is having a noticeable effect (on the right side of the pic).... Just don't expect an overnight miracle - I've been exceeding the recommended dose timing, since no fish are at risk. I'll change out the water a few times before that.... An added bonus - it appears to have killed off all of the little nuisance snails... ... show more
