After using this product, right away I noticed a reaction with my Goldfish. I have (had) two and the one was affected more then the other. Did a water change and they seemed better. A few weeks later I used it again and then I lost the one fish. For the last few days, even after 2 partial water changes my lone goldfish is VERY stressed and going crazy. Today I'm doing another 2/3 water change and hoping for the best...
Google "Algaefix and goldfish" and read some of the reviews you find there. Some folks think this product should be banned, and I agree wholeheartedly!
The first time I used it, I used it according to directions. I counted out 14 drops for my 10 gallon tank. It cleared within a couple of hours, and then the next day, the algae bloom was back, so I waited three days, like the directions said, and put in another 14 drops, and the next morning, my fish were all lying on the bottom of the tank. When they didn't respond to even food by noon, I got them out of the tank and put them into our quarantine tank until my husband could come home and completely empty and clean everything in the 10-gallon tank. I would not use this again. I hope my fish will be okay. After several hours, they seem to be coming around. If they die, I will write back with an update not to use this product.

I'll keep this short and sweet I followed the directions and used this 3 times -no luck.... the water in my waterfall with constant aeration is still green. I think there are better products on the market. I hope this helps.

I picked this stuff up after going through 3 algae blooms in my 10-gallon tank (including one really bad one, couldn't see two inches past it, and the other two being much more tame).
Now, I've read MANY mixed reviews on this product before making my purchase, and I have one thing to say. This is basically Weed-B-Gone for aquatic environments. It's made to kill algae. It's safe for fish IF USED RESPONSIBLY.
We've treated two tanks with this stuff: a 60 gallon, and 10 gallon. No fish died.
The 60 gallon: heavily infested with algae, specifically the brown hair algae. Applied the recommended dose (1 tsp per 50 gallons, we did a full dose). In the tank live two Convict Ciclids, two loaches, two kissing gourami, one minnow, and one otocinclus catfish. The tank itself is very well established bacteria wise, and has an appropriate canister filter going with four sponges and bacteria media. The lights on it are low-light, with one low-light grower. NONE of the fish were affected in any way shape or form.
The 10 gallon: houses my one Oranda goldfish, along with 7-8 trumpet snails. Previously had ghost shrimp in it, but took them out prior to treatment, then ended up dying from separate causes (put three in a bowl, two died, the rest were killed by the stress of my goldfish chasing them and trying to eat them, I don't plan on getting any more, lol). As I stated above, went through three algae blooms/cycles before I bought this, and has an AquaClear 30gal. filter going with two sponges and bacteria media. The light on this one is a 96wat four tube grow light. The light penetrates a solid inch into the gravel, it's intense.
WHEN I DOSED MY 10 GALLON: bottle says 1ml/10 gallons. From what I'VE been personally taught from my boyfriend (his 60 gallon has been running for 10+ years with absolutely no problems), the more gravel that is in the tank, less water; resulting in a smaller dose. I put HALF of 1 ML in the tank. My goldfish is UNAFFECTED, and my snails are as happy as could be cruising around. After repeated dosages, and even one dose being a full dose, my fish is fine. And now after about two weeks, I've seen NO new algae growth, AT ALL. I'm going to continue treating the tank, as it is planted and the algae has taken a liking to the plants, but as far as I can say, nothing has perished in my tank using this product, other than algae.
With more heavily infested tanks: from the 60 gallon, it's petrifying to watch. When you treat it, the water will cloud up almost IMMEDIATELY. And it is and was scary to see it happen so fast. It was back to normal clarity overnight.
Further research into this also relieved that the chemical diminishes in 24 hours, being completely gone by 48 hours. Example: I haven't changed the water in my 10 gallon since I've started using it. By the amount of chemical I've put in, I'm positive my fish would've been long gone by now. But he's still in perfect shape and health.
Everything being said: use this with CAUTION! This is not a magical algae fix (well, was for us....), this is made to kill algae, and I'm sure with inappropriate usage, will kill a lot more than algae, including what is printed on the label. If you have any doubts about getting this product, find something else. And if you get it, use your brain. It's easy to over-dose, and some things just don't work with some people. In my case, I began with a half dose, because my tank is one of the fairly smaller ones, and I wanted to see just how my fish reacted to it. I gave it a day, then repeated the half dose, waited, continued with a full dose over the course of a week and a half. It's not the products fault, as it's working BEAUTIFULLY for our own tanks and MANY others.

I never use chemicals in my tanks but this time I decided to try because I developed an algae problem in one of my tanks that I could not get under control after adding t5ho lighting (Even after reducing light duration). Since I am averse to unnecessary chemicals entering my tanks I only gave a half dose after a water change yesterday. When I awoke this morning I had a lovely tank of dead fish. There is nothing else that would have contributed to the entire tank being wiped out but this hideous product ( My ammonia, nitrate and nitrite levels are fine). I wrote API about it and am awaiting a response. STAY AWAY from this and use any other method of destroying algae that does not consist of using this product (Or any other chemical product for that matter). API/MARS should be ashamed to have this on the market.

I have a small koi garden pond, 500 gallons or so near the Cleveland, OH area. This past winter (12/13) I had enormous amounts of string algae form in the pond over the winter. I do have a UV filter on my canister filter that helps keep the algae under control, but I do not use that in the winter due to freezing. As the weather begins to warm and I prepare the pond for readiness I needed to find something (beneficial bacteria) to help me clear the sludge that was forming as I killed off the algae and also the other leaves and matter that had collected over the winter. I scooped out as much of the debris as possible, but there was still a lot of residual matter on the rocks, sides and bottom. I did not want to drain the pond. I purchased these blocks in hopes of helping me get the pond cleaner faster. After treating the pond with an algae treatment a few days earlier I added one block to the pond. Within a matter of days the matter began to be removed. I did have to clean my filter at least once a day sometimes two. The water now is crystal clear and I can see right down to the bottom of the 3 foot pond. The fish are happy and thriving, I leave them out all winter with the pump on low everyone is happy, me the fish, the other wildlife. Great product and worked for me with the combination of other things I was doing to clear the pond after winter.
