Review: Quick and amazing results - Absolutely amazing was very skeptical at first had tried everything but wow two days and my water is crystal CLEAR !! I have a 450l jewel rio amazing filter water changes but it still happened and it was getting worse I tried this and wow I am honestly taken back I am new to the tank world but my fishes red tail shark pleck and loach are very happy again
Review: It works so thankful as I was at my wits end - I have a 80l tank ish I think. It was like pea soup we have a lot of natural light and do t use the aquarium light to keep the algae down. I could not stop the green. Purine sachets, water changes. Took live plants out. Nothing. Tried this with a 3/4 soft water change. This is after 5 days. It’s clearer than a swimming pool. I did leave it on all night first night and killed 5 fish. My mistake. It’s in the filter housing space but it attracts fish at night like moths so just use it in daylight not dark or use a timer. I haven’t had it on today as the water is so clear but maybe I will use it 1-2 hrs per day but also need to make sure the prawns and snails have something left to eat. Yes it was cheap it may not last but it does work and I am happy. Very happy.
