Hydor PRO-00621 First Impressions


Initially this was used as a sample packet came with our aquarium. If you have a freshwater fish tank, I highly recommend this product. I have two goldfish and a Corydoras catfish. This is my go to water conditioner and stressed fish treatment. The chloramines contain a small amount of ammonia. It has been 4 days and our beta is loving the clearer water. Easy to dispense the product without mess and easy to use per instructions.

Hydor PRO-00621 Final Thoughts

Sky high ammonia.

Fish seem healthy and active during use. I love all of the API products, especially their easy to use test kits. I've used every product on the market and this is the most AMAZING MUST HAVE PRODUCT! My water is crystal clear like the first day i filled it and i could be happier. You have to understand when to use this product, and what is is used for. This is my go to water conditioner and stressed fish treatment. I have used this consistently since cycling my small sized fresh-water tank.
