Magic in the bottle
I bought this in late 2023 and i was scared to use it because i wasnt sure if it can be used with fish or without since ja uary my 100l tank is suffering from algea and it takes me atleast once in two weeks take decorations out with clean sponge wipe off algae from the glass and then remove some water and replace with clean treated water ofcourse fishes stressed always and it took hours for me to do it my hands were dry as sponge after but then algae again appeared and it grew really bad on the glass so i thought ill take decorations out scrub them off and wipe the glass i didnt want to do all the big work of removing water exchange etc… so i wiped the glass and ofcourse all the algae thats been wiped made water really green and cloudy even though we have fluval filter but algae is something have to fight too much and i struggle doing all the hard work so i thought ill try this fluval water clear i poured one cup with fear but it was like watching magic it just like wave went and after few minutes i looked fishes are alive happy and water is crystal clean ❤️❤️❤️😲 i am in shock its magic in a bottle

I could not clear my TANK! Well it works and didn't kill my fish..
So I have used this as instructed in my tank, I have kept fish for almost 20 years and I just moved house, a tank of mine (see picture of now clear tank) would just not clear, I had done multiple water changes, I had reduced lights, changed filter. I did water tests and all the parameters were fine. Basically everything I could think off I did, I am very careful when adding chemicals to tanks as the last think I used (not related to this) wiped out all my shrimp. So it was like a milky cloud, in my opinion it looked like a bacteria bloom. I thought it was the tank cycling as I have a fully planted tank might just be taking a bit longer. 2 months passed I still could not fix it, you could not see more then 2 inches into the tank! So I bought this stuff, I was worried when I read the reviews and some people said there fish died. I don't know if with more sensitive fish they might but I have not lost 1, and I have aboht 50 shrimp on my tank they are also very happy. I used the treatment for 3 days until the tank was clear and it seems to be steady now. Very happy with the product!

I love this product!! I’ve been purchasing it for years!! My local pet store stopped supplying it because I was the only person buying it but I can tell you this stuff works you put it in your tank and within a few hours your tank is clear it doesn’t matter if it’s food residue algae fish poop or just elements in the air. It takes it all completely away. I have a 75 gallon tank and 150 gallon tank and I pour the whole bottle in and it works wonders I’ve tried to measure it and do that but for me it doesn’t work because I have turtles and fish and one aquarium and all Koi fish and smaller type fish in the other you also have to buy with it the fluval water polishing pads they’re white and the black one that’s cut in half if you use the system no matter what filter you have you will have Clearwater. In one aquarium I have two canisters and one that hangs off the back and each filter has the white polishing pads and the black pad in it and let me tell you I am so pleased I found this system. So if you’re struggling with dirty water cloudy water try this you will not be disappointed and it’s way way way cheaper than going to Petco Petsmart or your local fish store.

I poured it in my little pond, but the water clarity did not change. Probably it is suitable just for the aquariums.
