API Splendid Betta Complete Water Conditioner, 1.25-Ounce Bottle - Safely Removes Chlorine and Heavy Metals for a Healthy Aquarium Environment

Doris Ranke: What I like the most about this conditioner is that I don't have to condition the water ahead of time when cleaning the whole tank. I do let the water come to temperature then add the conditioner and then add the mix to the tank. This makes cleaning the whole tank or just adding some volume so much easier!!

Bluevivid: I like this water conditioner. It's easy to use with the drops and to measure. Easy drop measuring for weekly 25 percent water changes. No complaints from my Betta...she's a happy girl.

Victor: This product gives directions for almost any amount of water. This is unlike most which gives you the amount to add in gallons. Very convenient!

Adam: La verdad no se si son cosas mías, pero el agua se hace más clara, cristalina y se ve muy limpio por días. Mi betta le gusta y ya no hace tantas burbujas como antes, aunque no se si sea bueno o malo eso.

Amazon Customer: I've used this a few times since receiving it and so far I like it. I use it in combination with some fizzy tabs for my beta and between the two everything runs smoothly. Just by itself it should be go to go though. I have used it alone once and everyone in the tank is still happy and healthy and my water levels were within a good range.

Brett: I use this stuff all the time and is a MUST for smaller fish tanks. I buy multiple bottles at a time because Betta fish require a weekly 25% water change and I go though a bottle about every 2 months.

Directions are easy to follow and I like the fact that it tells you how many drops per how much water (usually something smaller like number of cups). Similar items tell you how many teaspoons or whatever per gallon or 10 gallons so you are left figuring out a conversion for smaller fish tanks.

I would also recommend the same API brand and their AlgaeFix for every water change:
Aquarium Pharmaceuticals® Algaefix (1.25 oz.)

SelinaB5: It makes cleaning out the fishbowl so much easier and it's so inexpensive that I can't help but rave about it. The fish are doing well and it's instantly ok to use tap water with them because of this stuff. I'm so happy with this product. I use a 4 cup measuring cup to do the drops and measure the water before pouring it back into the fish bowl.
