Algaway 5.4 Algae Remover for Aquariums, Algaecide for Freshwater and Saltwater Tanks, Aquarium Algae Control and Fish Tank Cleaner, Safe for Fish and Plants, 8 Ounces (ALGAA08)

At first it didn’t work, water stayed green, did a 50% water change when moving houses and did two applications, at one point keeping all lights off for 24 hrs, worked like a charm, crystal clear water now. A+

Just buy it! Cleared my tank up in less than 8 hours!

This stuff works very well to common algae. I have not used it on bubble or hair algae. I highly recommend it

Does not work on algae attached to glass,rocks or plants. I used way more than the directed amount after not seeing any improvement for several days. Almost done with the bottle and algae is doing very well with no sign that this did anything

I will absolutely say that this product does what it claims; it clears up the algae (my five gallon betta tank gets ridiculously green no matter what light sources and how much cleaning I use). However, something to keep in mind if you have a smaller tank is that this product and its included measuring cup-- which is really nice, much better than measuring in drops in the top of the cap! -- really is set up for larger setups, and this product WILL harm your fish if you overdose. I think the product is great for clearing a fishless tank or if you have a larger (20 gallon or more) setup. If you have a smaller setup, like I do, I would keep a look around for other products.

This product actually did exactly what it promised. My tank was crystal clear in 5 hours. No harm to fish. Now my tank is very well aerated, and that's very important with such rapid algae die off. But this product works!

I'm not so sure this is doing anything. It did kill each and every snail I had in the tank. Still getting algae on the glass and plants.

Works great very quickly. But please be very cautious with the dosage because it can harm your fish if you didn’t use properly. I would even recommend using less than the recommended dosage on the bottle, for example if the bottle says 1/2 tsp i would put 1/4 and give it couple days. I also recommend doing a 20-30% water change after the water clears up. I used it in my 5 gallon tank and I redid the math to know exactly how much i need to put. For 5 gallon tank i used a little under 0.5ml. My water never looked that clear. It works instantly to clear green water. Use only when needed.

Worked flawlessly. My aquarium was algae free for 6 weeks after 1 dose of the recommended amount. Very happy with this purchase.😁

Best pro duct. Use dose only as suggested.

The product didnt work on my green spot algae and killed my 5 fishes , i used in recommended dose .
