Affordable, and Effective Water Conditioner
Iâve been using API Tap Water Conditioner for years, and it has consistently delivered great results. For me, itâs the perfect balance of effectiveness and price, it works just as well as higher-end brands, but at a fraction of the cost.A 16oz bottle lasts me around 5 months while maintaining two aquariums (a 20-gallon and a 40-gallon), which makes it an incredible value. The built-in measuring cap is a simple but very handy feature, it takes all the guesswork out of dosing. My routine is to add half the recommended dose while refilling the tank and the other half once itâs completely filled.In all the time Iâve used this conditioner, Iâve never had a single issue with water quality or fish health related to tap water treatment. Itâs easy, dependable, and budget-friendly, exactly what I want in a staple aquarium product. Highly recommended for any fishkeeper.

Best water conditioner.
This is my go to tap water conditioner, it has just enough to detoxify, just concentrated enough to not be overpriced per oz, and just clear enough to prevent disaster, the best you will get.

Awesome Product-Funky Smell
I bought this water conditoner for my betta tank. It does a great job and conditioning the water, and the measuring cap comes in handy. This stuff doesn’t detoxify ammonia and nitrite like Seachem Prime does, but still gets the job done for my betta. It is a huge bottle that can last forever as well! The only thing is the smell is kinda funky, like boiled eggs. However, this is a great budget conditioner!

Does what it’s supposed to at a great price
Does what it is supposed to do. Nothing really else to say. Keeps the fish healthy, no odor, doesn’t mess with water clarity, and dechlorinates the water. I find it to be effective and well priced. Would buy again.

I like this one because itâs just one drop/gallon. Makes it easy to add to fish tank. Most of the other brands have you pore it into the cap and are so many ml/gal which sometimes makes it hard when you only need it for smaller tanks. Sometimes I just add a few gallons and I put just 3 drops in. Easy and never had a problem and Iâve been using this stuff for years. Sometimes itâs hard to find as itâs out of stock. I used to be able to buy it in store but Amazon has been the only place I could buy it for many year for some strange reason.
