Kordon Novaqua Plus Water Conditioner, 16 oz

Kordon Novaqua Plus (model 33156) is an aquarium water conditioner in a 16 Ounce bottle. Kordon lists two main jobs: it removes heavy metals from tap water, and it provides health aids, including immunizers and vitamins, for fish.

Heavy metals in tap water

Copper, zinc and other metals can enter water from household plumbing, especially in older buildings or when water has sat in pipes overnight. Fish tolerate some metals poorly, and invertebrates like shrimp and snails are even more sensitive to copper. Running the tap for a minute before filling buckets and using a conditioner that targets metals both help.

Health aids for fish

The vitamins and immunizers are aimed at fish under stress: new arrivals, fish moved between tanks, or fish recovering from injury. That makes Novaqua Plus a reasonable product to use during acclimation and after netting.

What to check on the label

The product listing is brief, so read the bottle for the dose and for whether your water’s disinfectant is covered. If your city uses chloramine, confirm the label addresses it, or pair Novaqua Plus with a dechlorinator that does, such as API TAP Water Conditioner.

Using it at water changes

1. Fill a clean bucket at tank temperature.
2. Dose for the volume of new water, per the bottle.
3. Stir and add slowly to the tank.

When a different product fits better

• For ammonia emergencies, a conditioner that binds ammonia such as Seachem Prime is more appropriate.
• For slime coat protection, see API Stress Coat.

Who it suits

Freshwater keepers with older plumbing, those who keep metal-sensitive invertebrates, and anyone wanting a conditioner with fish health aids for new or stressed fish.

Storage

Keep the bottle capped and out of sunlight and heat. Write the date you opened it on the label so you know how old it is.
