Mean on the Green... Safe for Fish! Liquid algae control for aquarium, fountain, and small pond use.  FAST acting - No More green water, algae growth, or string algae.  Safe for fish and live plants.  Will NOT cloud water.  AlgaeQuel is an algae eliminator for freshwater aquariums, small ponds and fountains.  Safe for pond liners and made in the USA.

NovAqua+ is a best quality water conditioner for all water sources.  NovAqua+ removes heavy metals from tap water, dismantles chloramines in water, removes chlorine from tap water, provides health aids - including immunizers and vitamins to fish, provides protective slime coatings to fish (slime coatings repel viruses and bacteria), is compatible with all of Kordon's water conditioners and fish treatments.  NovAqua+ is Amine-free and made in the USA.

The original NovAqua replaces fishes' lost skin slime with Virus and Bacteria Resistant coatings, add electrolytes to the water necessary for fish health, disassembles toxic chloramines in the water and removes chlorine, removes copper and other heavy metals from the water, stabilizes by buffers pH of tap water, amine-free and made in the USA.

To avoid confusion it should be recognized that there are two products with the Amquel name - the original Kordon AmQuel and the recently much improved product Kordon AmQuel+ (also called AmQuel Plus)   AmQuel+ does all that AmQuel does and a significant number of additional tasks as well.
So why does Kordon continue producing regular Amquel, if AmQuel+ is supposed to be so much better?  There are those loyal to the original product, and they are used to what it accomplishes.  Also, AmQuel+ naturally has a nontoxic  odor (now being suppressed with odor eliminators for the AmQuel+ product) that some find objectionable. 

AMQUEL+ AS THE PREMIER AMQUEL PRODUCT
To avoid confusion it should be recognized that there are two products with the AmQuel® name - the original AmQuel which Kordon has been providing since 1985, and the recently invented product AmQuel+ (also referred to as AmQuel Plus) which is based on a much improved new chemical formula.  AmQuel+ is the latest development in state-of-the-art water conditioning technology and is far beyond what the original AmQuel product does. AmQuel+ does all that AmQuel does and a significant number of additional tasks as well.... more info

KORDON'S Pond·Prep is a dry powder that should be added when setting up a new pond, or when restarting a completely cleaned pond, or when adding water to a new pond. Pond·Prep sets up the pond completely, making it ready for proper nitrification to begin and preparing the water for the fishes. For the initial start up, no additional chemicals are needed, Pond·Prep will remove all chlorine, chloramines, ammonia from new water and it helps detoxifies copper and other heavy metals often found in tap water. Pond·Prep will add needed electrolytes and skin slime replenishers to prevent or minimize stress on the newly added fishes.

Pond·Prep reduces the toxicity of nitrite and provides trace elements needed to establish and maintain biological filtration. Pond·Prep supplies the electrolytes and minerals needed by fishes in new pond water. It adds buffering components to help boost and maintain the necessary acid-neutralizing capacity (alkalinity) of the water.
