The only conditioner I use is Seachem Prime. It is the only thing I will ever use, IMO the best on the market. A very small amount goes along way (roughly 2 drops per gallon). Even with 10+ tanks ranging from 1-10 gallons a 250ml bottle still lasts me months.
I would stay away from anything marketed solely for bettas. Generally you are paying more for a watered down version of a better product. I also wouldn't buy anything where they misspell the name of the species the product is geared towards LOL..
- 2.5 mL Betta Ultimate offers an easy-to-use dispenser and treats 16 ounces of water with just one drop
- The product cannot be overdosed and residual product in the water will remove ammonia put there by your beta
- Give your beta the best environment possible using Betta Ultimate's patented technology and ordinary tap water!
I thought that was funny
