Laura V. Babb: Not sure how this stuff works, but my fish was buried under the rocks for nearly 3 weeks. He had lost many of his pretty fins. I cleaned the tank and he still didn’t move much and wouldn’t eat. I used this product and he’s back to life and looking better than ever.

I would highly recommend this product.

Katharine Cushing: I feel like I can never do enough for my 2 bettas. They each have their own 5-gallon tank. I wish I had not bought this now, because I did have their water perfect! I've been using Tetra Cleaning Bacteria in their water to build "good bacteria" colonies in their bed and filter. So, I thought this would be "even better." Shortly after using it for the first time, BOTH tanks showed raising alkalinity do the danger region. I did a water change with properly conditioned R/O water (which is more naturally acidic). That helped for a while, but I've had to do emergency changes when my test strips and API Test Kit analysis showed scary alkaline. Boo hiss! I cannot say for absolute certainty that THIS product did it, but I'm not trying it again. I just wanted to put that out there for other customers to consider. (PS - Plus the instructions are so terrible, and confusing! After spending a long time trying to decipher what to do, I chose to "spritz/spray" the stuff on top of the tank water. A couple of days later, pH and alkalinity rose in ways I have not ever seen.)

Client d'Amazon: Bon supplément mes poissons l’aime bien ils pop comme des bonbons la-dedans! ils sont en santé et plus calme bon surtout pour les poissons plus fragile vais surement racheter le produit! Je ne conseille pas le mettre directement dans l'eau a moins que vous ayez un petite aquarium sinon ça gaspille trop.Moi je le donne pendant que je donne du congeler ou je fais la nourriture moi même et j’en met dedans C'est efficace .A une bonne senteur de ''fishy'' les poissons aime ça.le live c'est plus difficile un peu par contre a moins que ce soit des vers je ne le conseille pas. j’en ai mis avec des fairy shrimp et des arthropodes... ils sont mort avant de les mettre dans l'eau. Mais c'est vrai aussi qu'on ne peut pas surdosé le produit, Les poissons les invertébrés vont bien j'ai eut aucun problème. La première fois j'ai mis le produit directement dans l'eau j'ai une 75 gallons alors j'en ai mis XD je sais pas le live ça doit être trop petit pour moi ça pas marché.

Huy: Really than my expectations, our fishes look starving and search every corner to find foods. They are more lively and healthy. Great products because we have the aquatic showroom: Pet Travel Online in Raleigh, so we always search bio-tech products for our fish. These products of this company certified our wishes. Low cost to invest but effective. We appreciate.
