Tantora Betta Spa - Natural Water Conditioner

My main issue with this product is the whole "siam ancient secret" point; not that I think Tantora is going to try at poisoning my betta, but I'd still like to know. The other is that this product is clearly intended for betta kept in smaller environments (even... I shudder to think of it... bowls!!!), as the instructions are saying that one packet is good for only 2-3 liters of water.For what they are, I believe these little tea packets to be overpriced. I should think that Indian Almond Leaves (also sold on Amazon by Tantora) do almost the same as these packets are advertised to do, and you definitely get more for your money.((If you are looking to improve the quality of life for your betta by purchasing products like this, I would urge you to reconsider a moment what exactly it is your betta is needing! Is your tank/bowl large enough (2.5g), heated, cycled, and maintained on a weekly basis? Have you been feeding him quality foods and providing safe hideouts? There really are no shortcuts in the fish hobby!))In the future, I would not purchase this again but simply go back to the Indian Almond Leaves, as they both release the tannins, have anti-bacterial/fungal properties, and can soften the pH. The only difference is what Tantora claims to be their "special blend".... But since we have no idea what that is, I cannot vouch for that... ;) Hope this helps!
