Superb products.
Superb product. API is one of my resources for many of my aquarium essentials. Never had any problem with any of there items. Great value for money, with many products giving you size options for what you need. All products from medicated to water parameters and plant care. These products are made with an ease of understanding for what that purpose is and will help you on your fish keeping journey.

Water Conditioner.
I have a 100 liter aquarium with turtles. This water conditioner has become the best for me of all those that I have bought before. I do a water change once a week, with this water conditioner even after a week the tests show that the water parameters are normal. Although I have used various other water conditioners before, recently I have been using AquaSafe and NitrateMinus, but after a week the tests showed an increase in nitrates. I am very happy with this water conditioner, I definitely recommend it.

Makes water safe for fish
Easy to use, instructions tell you how much to put in. Doesn't harm fish. Water is clear. Works well, helps the plants stay healthy. Great quality and value for money

Good value
Worked as expected, the water took time to clear. Instructions were on the bottle. Straightforward to use. The cap also functions as a measure. Worth it. Good size bottle too.

I first received it as a sample when it first came out in 2022 and after trying it I have been using it ever since. A small bottle lasts a long time even with 2 tanks (a 15 and a 55) I used to use another one and prime but now I just use this in place of both. Its cost effective and my fish are doing fantastic. The trick is to shake it well and use a syringe to measure it, its very concentrated.

This stuff is great for binding ammonia and nitrites. I started using it after a bacteria crash and I now use it as my regular water conditioner for almost all my tanks. In my experience, it did not actually remove any nitrites or nitrates, but it certainly keeps the fish more comfortable in a crisis. I also only use a slight amount more than the regular dosage to detoxify (necessary because our water is highly chlorinated here) and do not use the higher dose as instructed on the second part of the directions label because when I did, my fish appeared very stressed out and lost some color (though I should note that I did not lose any fish, a water change and a lower dose did the job just fine after). I'm still giving this a 5 star review however, as it was a life saver for a tank crash and seems to be comparable to the higher priced products that are meant to bind toxins and keep your fish safe. I don't think there are any products that can truly remove the nitrites and nitrates, and no matter what if your levels aren't going down you can't avoid the extra water changes. But we keep this stuff on hand at all times now.
