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.

I'm amazed, I'm really amazed that this product worked so well. Sure enough they are back to their healthy coloration and didn't end up dying on me. But the septic tank bacteria did nothing.
