Features 5

  • WATER CONDITIONER: Makes tap water safe for bettas and other ornamental fish.

Description

Tetra® BettaSafe™ conditions tap water to make it safe for your bettas (Siamese fighting fish, or betta splendens) by neutralizing harmful chlorine, chloramines and heavy metals present in most municipal water supplies. Condition water monthly to protect your bettas and reduce stress. Use 7 drops per gallon (2 drops per liter). Betta fish are best known for being small, colorful pets with big personalities. Male bettas in particular have an amazing variety of tail shapes, ranging from half-moon to spikey and crown- like. Since bettas require minimal maintenance, they're a great species for beginners. If you’re keeping bettas in a larger aquarium with filtration, be sure the intake and water outflow are gentle. If a single betta is kept in a bowl environment, filtration may not be practical, so complete water changes should be performed weekly. Since 1951, Tetra has developed the world’s most comprehensive body of fish food knowledge, and fishkeeping enthusiasts have looked to the brand for products and solutions that add ease and beauty to their home. Whether you're an experienced hobbyist or just starting out, Tetra has everything you need–-from a large variety of quality fish food and innovative equipment to test kits and decor.

Instant Peace of Mind for Your Betta!
Size: 1.69-Ounce, 50-Ml (Pack of 2) Color: Golds & Yellows
The Tetra BettaSafe Aquarium Water Conditioner is hands-down one of the smartest choices I’ve made for keeping my fish tank safe and healthy. With just a few drops, it instantly neutralizes the harmful chlorine, chloramines, and heavy metals in tap water—no more waiting or second-guessing. My betta’s fins regained their color faster than I expected, and the stress level in my tank visibly dropped after I consistently used it. The dosing is simple, the bottle is compact, and it gives me confidence every time I do a water change. For anyone who cares about the well-being of their betta or small fish setup, this water conditioner is a total win. ... show more

My fish like it
Size: 1.69-Ounce, 50-Ml Color: Golds & Yellows
Easy to use, very effective and lasts a long time. Just 14 drops per gallon. I’ll keep buying it. I can do immediate water changes once I check on the temperature and ph of the new water.

A must have for your Betta tank
Size: 1.69-Ounce, 50-Ml Color: Golds & Yellows
My mother purchased a betta for my son they didn’t mention to her at the store that she’d need to condition the water prior to placing the fish in the tank. I ordered this the same day she bought the fish over and received the package that same night. I was impressed & relieved as I hate leaving them In those small cups they come in. I did cheat, I had the tank up & running for 12 hours and after I dropped the appropriate amount of drops in I only waited about an hour before putting the fish in. I felt bad. I believe they recommend you wait 24 to 48 hrs but like who has time for that when doing a water change? Anyway, the fish is thriving! ... show more

Great For Hard Water
Size: 1.69-Ounce, 50-Ml Color: Golds & Yellows
This is my absolute go to for conditioning my water for my fish. I have very hard water where I live and I believe this has made it possible to use my water to fill my tank. My fish are thriving after I started using this conditioner and before I was using it they were slow and lethargic. I believe that this removes all the hard chemicals and stuff that is bad for fish. I wouldn’t even drink the water so my fish will not be swimming around in it 24/7 until I have officially treated it with this water conditioner. I will definitely continue to use this for my fishes in the future ... show more
