Aquatic Experts First Impressions

"I love this product."

I love all of the API products, especially their easy to use test kits. Tim's cultures were obviously very alive and active. I used to use AmQuel years ago and then spent years out of the aquarium hobby. Good Product, Good Price Gets five stars! I do not use this as a product to treat my tap water. Its 9pm and the old cloudy water is now crystal clear! Initially this was used as a sample packet came with our aquarium.

  • KloudAway Freshwater Aquarium Water Clarifier - Clears Cloudy Water, Water Clarifier for Fish Tank, Made in USA
  • FAST-ACTING - KloudAway quickly clears cloudy or hazy aquarium water by CLUMPING FLOATING PARTICLES together making them large enough to be trapped by your aquariums' mechanical filter. To remove these particles from the water your aquarium must have a mechanical filter.
  • CUTTING EDGE FORMULA - Our advanced fish tank water clarifier is targeting unsightly particles in water such as uneaten fish food, dust and other debris to produce crystal clear water. KLOUDAWAY DOES NOT WORK ON "GREEN WATER" as algae continues to multiply.
  • SAFE AND EFFECTIVE - Our cloudy water treatment is SAFE FOR all types of FRESHWATER FISH, TURTLES, PLANTS, SHRIMP and OTHER INVERTEBRATES and has no effect on the beneficial bacteria in your aquarium's biological filtration.
  • REMARKABLE RESULTS! Use our aquarium clarifier to maintain sparkling clear water in your freshwater aquarium. For exact details of how to use KloudAway, causes of cloudy water and much more, WATCH OUR VIDEO "Clear Aquarium Water Fast"
  • Water testing is recommended. Cloudy water is often caused by New Tank Syndrome, which can cause dangerously high levels of ammonia and nitrite. Protect your fish from ammonia spikes with TankFirst Water Conditioner!

"00 product."

It didn't kill the fish or cause any problems with the water so I stuck with it. I have used this consistently since cycling my small sized fresh-water tank. No observable signs of stress in the fish. Fish would die occassionally every few weeks or so. The top is a measuring tool as well which I was not expecting. Tim's cultures were obviously very alive and active. I'm interested to see how long it works.

AQUABELLA BIO-ENZYME 11201 First Impressions

"5 stars all the way!"

I swim 5x week and usually my suits last about 2 months. It only requires 3 drops per gallon you add to your tank. If either or both ammonia and Nitrite are above 1ppm do not add ammonia. Thanks to the Amazon reviewer who mentioned this! More doesn't hurt anything, but it's just wasted. UV light works on it but not much else. Fish are aerobic organisms that are susceptible to ROS.

AQUABELLA BIO-ENZYME 11201 Final Thoughts

"The FIRST time."

I used to use AmQuel years ago and then spent years out of the aquarium hobby. Boy, I thought I was having trouble with my filter. Fish seem healthy and active during use. But the septic tank bacteria did nothing. The top is a measuring tool as well which I was not expecting. This is definitely worth trying if you have cloudy water. This allows the conditioner time for its anti-heavy metal ingredients to work fully.

"This a great deal."

It is just as good when compared to other brands of conditioner. Fish possess an antioxidant defense system to reduce the negative effects of ROS. I wanted to see if it would take the chlorine out of my swimsuit. This is only temporary till I get a spare dropper. Now our fish have grown and we've added live plants.
