All-in-One Formula Keeps Water Safe:

AquaSafe PLUS Water Carer is an all-in-one formula that works to keep your aquarium water safe and healthy for your fish. This easy-to-use conditioner detoxifies harmful ammonia in tap water, neutralizes chlorine, chloramines and heavy metals, and features stress reducing slime.

How it Works:

Tap water and well water contain dangerous substances like chlorine, chloramine, and heavy metals that must be neutralized for the health and safety of your fish. AquaSafe PLUS works to create a safe environment and maintain optimum balance between water changes by neutralizing chloramine and turning chlorine into harmless salt. AquaSafe PLUS also binds to heavy metals to create a large, safe molecule that can be physically removed by your filter.

New Vitamin and Mineral Blend:

AquaSafe PLUS features a unique blend of beneficial minerals that are normally lacking in typical tap water. These included vitamins and minerals work to increase the vitality, breeding behavior and activity of your fish.

Proprietary Advanced Biopolymer:

Proprietary, advanced biopolymers produced by living organisms such as kelp are included in AquaSafe PLUS to support beneficial bacteria necessary for healthy and clear aquarium water. These added ingredients do not pollute water, but work to reduce pollution by strengthening the bacterial bed.

    I have tried a few different brands in my seven years of being an aquarium enthusiast. This has multi functions but my main concern is my water gets so cloudy when I wait too long to change my filters. The water just wont get clear using just the filter system. I dont have chlorinated water because I have a well and the PH of my water is always dead on 7%. So cloudiness is usually my only issue. Unless algae starts to form. which is a rare occurrence. But add this stuff and its almost instant clarity. It dont take it long at al. It works really good especially for the price.

    Great bargain and gets the job done

    I have a pond in my back yard. I use this product to condition the water and dechlorinate it. I found this on Amazon and I could not believe how much less it was than the pet stores where I have been buying it. You get 2 large bottles in the order.

  5. Amazon Customer

    Large and useful

  6. Rob Adams

    Works instantly as I’m testing daily on a cycling tank and have had zero chlorine. Great product!

  7. P. Cuba

    I swim in a chlorinated pool three times a week and it prolongs the life of my suits.

  8. Tiffany Taylor-rheem

    Works great in our fishes tank. Clears rather fast. Product arrived fast. Easy to use.

  9. Pam Scd

    Mis peces y ajolote lo aprueban.
    Entre los acondicionadores para pecera que he usado, Tetra es de los que más me ha gustado, veo que le sienta muy bien a mis peces y a mi ajolote. Es caro, sí, pero vale la pena.
