I had serious brown algae (diatoms) in my tank, even though I do a great job of replacing water each week. My tank sits in a spot that gets morning sun, so I know this is a an uphill battle but I don't have anywhere else for my big tank to sit. I read the reviews and instructions for this product and it said it might take a week to start working. I added it to my tank yesterday (my entire tank was disgusting and I could barely see my fish through the brown glass) when I woke up this morning, I could only see tiny traces of the algae. My glass is almost clear again. Not sure how the heck that happened. Maybe 90% is gone after one day! And my fish are still alive and acting healthy, so this is a win win. PS I followed the instructions on the package exactly to make sure I didn't overdose my tank. I wish I had taken before pics because my tank was REALLY bad.

We ended up with a creepy film/scum on the top of the water in our red eared sliders aquarium. It looked almost oily. After trial and error we tried this and it works great, but definitely follow the guidelines, we didn't do it every 3 days at first and the creepy scum showed back up. Now we just have a few free floating strange spots, we will continue to use.

Been struggling with the clarity in my tank for weeks, changed water repeatedly, tried a clarifying product that did not work, reduced food, etc. etc. Then finally broke down and tried this product, and WOW! My tank is so clear, fish are so happy, now I do not feel embarrassed when people visit and look at my tank. Thank you for this amazing product!

The algae were killed within hours

Follow directions carefully. As a safety measure with all chemicals, we start out dividing the dose by ½ to see how the animals are affected. It worked for us at this dose and now only rarely dose as a maintenance to curb algae. Recommend with caution.
