Fritz Aquatics Slime Out Treatment for Stains from Red Cyanobacteria in Fresh or Saltwater Aquariums (20-Count)

I used this to kill off blue-green algae (it's actually a bacteria). Worked great, BGA was gone within a couple days.

Been working for 2 years to get the blue/green scum out of my 100 gallon aquarium. In the past, even tried a product that killed most of my fish. Highly recommend SLIME OUT as both curative and maintenance chemical.

Had to dose the tank that was giving me issues twice. Did so over the course of 2 weeks and forwent the water change the second time for a few days. It NUKED the green skin algae that moved in while I was on vacation (power went out and reset my light timers. Other tanks were fine but one ended up with the dreaded pond muck for some reason).It worked great in removing it. It all melted away over the course of a few days once it started working. Didn't harm my plants or snails either. Simple as mixing into some water and pouring into the tank. It even ended up cleaning my white sand of the greenish dusting of algae it had, which was nice.Just be careful if you have plecos, mystery snails, or anything else that relies on algae growth for food. You may need to supplement their diets more than normal when all the algae disappears.

I have a 65g freshwater aquarium that had a massive Cyano outbreak. The slime would coat everything in the tank, and after removing it, it would be back in less than a week just the same. In desperation I purchased this product and wow, it worked like magic. I first cleaned out as much of the Cyano as possible, and then used two pouches. It comes in a powder that I mixed with some aquarium water and poured it in. Did a 25% water change two days later and the Cyano disappeared. A month later still no sign of it. I have shrimp, angles, clown loaches, and live plants and no adverse effects. Even my good algae was fine. Highly recommended.

I didn’t even clean the bacteria slime out of the tank first and I was pretty over run by it in my 75 gallon tank. First treatment 90% was gone I was absolutely amazed. Definitely a must have even if you don’t need it yet.

I had blue green algae, cyanobacteria in my freshwater aquarium. Nasty stuff. Used this product once. It works. I was so happy because cyanobacteria grow quickly and was starting to take over my tank! The aquarium is heavily planted and has fish. Product worked only on the cyanobacteria, plants and fish were not harmed. Fish didn't even seem to notice. It's a good product and I recommend it for removing cyanobacteria.

I absolutely love Fritz products. Does exactly what the box says.

I am following the directions to the letter and it is not helping. Perhaps I have a different problem but what I do have fits the description.
