  • Fail or holy grail...?
Size: 8 Fl Oz (Pack of 1) Style: Aquarium Treatment
HOLY GRAIL!!! This is THE best stuff ever. My fish LOVE it and it lowers their stress so much so their colors came back and they look so much happier. I have cichlids and color is very important to defining if they are stressed out or not. I have used many pet store recommended (just because they are expensive) water conditioners that aren't even scratching the surface to how much I love this water conditioner. ... show more

  • Happy fish
Size: 8 Fl Oz (Pack of 1) Style: Aquarium Treatment
My betta ended up tearing his fins on some driftwood I had in the tank (I’ve removed it since). He was very lethargic and I was afraid that he wasn’t going to make it so I took to the internet to figure out what I could do. A combination of this and aquarium salt has helped him have a complete recovery. He’s in a 5-gallon and sometimes that makes it hard to judge how much of something to put in. This product states that you can put in extra if you’re trying to help damaged fins which took a lot of the stress out of worrying about overdosing the tank. Please also note that this isn’t a water conditioner, you will need to add that separately. I plan to continue the use of this product in weekly tank maintenance. ... show more

  • Great for bettas!
Size: 8 Fl Oz (Pack of 1) Style: Aquarium Treatment
I took on a ragged betta fish a few weeks before Christmas and had to start from scratch with his tank. so i purchased this and a few other water conditioners and medicines for bettas from Amazon. This has really helped condition the water to be safe for my betta and I think it has also been helpful in making his fin rot go away and keeping him happy and healthy. When i got him, his fins were torn and rotting. he had very little energy. now he swims all over the place and his fins look great. Highly recommend! ... show more

  • Use this regularly. Highly recommend...
Size: 32 Fl Oz (Pack of 1) Style: Aquarium Treatment
I've been using this regularly in my freshwater tanks since fall of 1999 without fail or any issues. I highly recommend it to keep your fish healthy and safe in tap water. Use it regularly to remove chlorine from your tank when first filling up the tank, when during water changes and when adding fish to your tanks. Highly recommend. ... show more

  • Cheap, readily available, works great.
Size: 128 Fl Oz (Pack of 1) Style: Aquarium Treatment
Been using this product for years now and it's done its job just fine for my small tanks i just fill up a 5 gallon bucket same temperature as the tank water and i add a cupful to it. For my large tank I fill it with the Python no spill clean and fill hooks up directly to the tap and i add the Api to the tank as the water goes in. I found that it took a full minute to fill a 5 gallon bucket so as the water is going in the tank im watching a timer and every minute I add a cupful which is a little overkill but I'd rather be safe than sorry because sometimes the water treatment will add extra chlorine to the water. The one little con is that it does cloud the water for about a day but maybe thats because I add more than I need but it still gets the job done its cheap and readily available. ... show more

  • Best buy!
Size: 8 Fl Oz (Pack of 1) Style: Aquarium Treatment
Excellent product for the price. The water quality in my tanks and my fishes' health have always benefited from using Stress Coat. Totally safe (I have freshwater tanks) and I use the Python for my water changes. I make sure the water temperature is correct and add Stress Coat and Stress Zyme as I fill. Use as directed and you can't go wrong. I use all API products to maintain my tanks. Best bang for the buck. ... show more

  • Stress Coat or Prime? I choose stress coat.
Size: 32 Fl Oz (Pack of 1) Style: Aquarium Treatment
I hear everyone swear by prime. But you know what? I like using my stress coat...I especially like the fact that it has aloe in it to help keep the fishes slime coat nice. I have used prime before...but unless you have a 150+ gallon tank that you need to do water changes on, stress coat is the one for me. ... show more

  • Bottle arrived with a sticker that says "Damaged"
Size: 8 Fl Oz (Pack of 1) Style: Aquarium Treatment
I received a bottle with a sticker that had the handwritten word "Damaged" on it. The bottle was also missing the cap. The safety seal was still in place (good thing, because I ordered several items that were shipped together in one box). But without the cap, I cannot close the bottle after I remove the safety seal. In any case, I will not risk using this product in my aquariums. I question the quality control of this product and do not trust the contents. Even if I did, I couldn't store it without a cap. ... show more
