Tetra AquaSafe Plus Water Conditioner, 33.8 oz

Tetra AquaSafe Plus is a water conditioner and dechlorinator for freshwater and marine aquariums. It neutralizes or removes chlorine, chloramines and heavy metals, so tap water is safe for fish, and it adds ingredients aimed at the fish slime coat. This listing is the 33.8-Ounce bottle.

What is in it

Tetra describes a formula with natural biopolymers plus vitamins and minerals. The biopolymers support the protective slime coat, the layer that shields fish skin and helps wounds heal. That makes AquaSafe Plus useful after netting, shipping or squabbles that leave fish scraped.

When to use it

• Setting up a new aquarium
• Partial water changes, including monthly ones
• Topping off evaporated water with tap water

Heavy metals

Older plumbing can add copper and other metals to tap water. Copper is especially dangerous to shrimp and snails. A conditioner that handles heavy metals is a sensible choice if you keep invertebrates or live in an older building.

Good habits with any conditioner

Match the temperature of new water to the tank, dose for the volume you add, and avoid big swings in pH or hardness between tap and tank water. Conditioners make tap water safe; they do not replace a cycled filter. If ammonia shows up, the cause is usually overfeeding or a young biofilter, and a bacteria product like Tetra SafeStart Plus can help.

Why the large bottle

At 33.8 ounces, this size suits several tanks or larger aquariums. Store it capped, out of direct sun.

Alternatives

For a concentrated conditioner that also binds ammonia, many keepers use Seachem Prime. For a similar slime-coat focus, see API Stress Coat. Choosing among them comes down to dose size, price per gallon treated and whether you want the extra protectant.

If you keep the bottle near the tank, a measuring cap or small syringe makes dosing a partial change quick and accurate. Mark the bottle with your usual dose for your bucket size so anyone helping with maintenance gets it right.
