OZPOLISH Bio-Cure Advance by Aquatic Habitat | Aquarium Beneficial Bacteria | Deep Cleaner, Reduce Ammonia for Fish Tank/Pond and Aquaponics System | Freshwater and Saltwater (Dry; 100 g)

I accidentally used 8 times the recommended dose, as I made wrong calculations 😳. By the time I realised, my fishes were already gasping for oxygen and the tank was hazy. I swiftly took out my fishes and turtle. Left the tank in that condition for couple of days as I wanted the excess bacteria to die by themselves, when they are out of food, which also meant that all the organic waste in my tank will be consumed which was too much.Once I observed them to be dying (you'll know when that happens, cloud starts to go away), I thought they might be dying cuz of lowering of pH, so changed 20% water after 2nd day, then again 20% water on the third day and changed 50% percent water on the fourth day and then added half of the recommended dose for my tank, added fishes and turtle on the same day.By this accidental ninja technique, I observed that my very dirty tank (as turtles can be bit messy and produce alot of poop), I was able to seed my tank in just 4 days (it generally takes about a month) and I had never seeded it before.Fishes and turtle seems to be doing fine, will change 20% water once more tomorrow just for safety as I don't have water testing kit and don't want my nitrates to be high after the cycling.So in short the product seems to be working fine, as when I added the product into tank (even though 8 times the quantity), couldn't see anything at first but after 5-6 hours when bateria woke up and started reproducing, I could tell that they really were bacteria. So the product works, you just need to have proper knowledge and patience. I would suggest, if you have never cycled your tank before take the fishes out then add 4 times the recommended dose and follow the procedure described above, if your tank is not dirty enough add some fish food to produce ammonia for bacteria. Also add a good filter media such as bio-rio or something similar.The process described above is for non-planted aquarium, for planted you'll need to do your own research otherwise your plants will melt. A more frequent water change during this process will do in planted I guess.Update : It's been 2 weeks and the aquarium is cleaner than ever before.

It's bit costly side, but effective also, I put one tea small spoon benificial bacteria, which maintain the nitrogen cycle!!!!

After tank cleaning I used a pinch of this product on my 100 litre tank. This review I am giving after 3 weeks of using this product. The water looks sparkling. Fish smell in water isn't there. Dirt and scum separate much quickly and settle at the bottom. My fishes are not stressed on adding this product. They have adjusted well. I am used to doing water change for about 1/3rd of the tank every week. After using this product I just add the water that gets evaporated as the fishes are fine. Good product.

I think that this kind of product should mention the expiry date innthe ad, as medicines do.It did the job in the first few months, but since I've a small waterbody, I need very small amounts. Now it's not working. Maybe it's expired.

The media could not be loaded.  This product really works. I have done 2 water changes and added the ozpolish twice and I have crystal clear water. My tank is more than 8-10 years old..

Nothing this product cant work its make water more cloudy and doest provide clear water

Very good

Important for every aquarium
