Awesome Aquatic Tourmaline Balls Tourmaline Mineral Balls Aquarium Water Treatment, Regular, approximately 1 cm

Tourmaline mineral balls are placed straight into a freshwater tank or its filter compartment, where they release mineral content into the water over time. This pack holds 10 Regular balls of roughly 1 cm each, and the manufacturer's directions allow about one ball for every 2–5 gallons of aquarium water.

The 10 Regular balls in this pack

The pack contains 10 Regular tourmaline balls at approximately 1 cm in size, matching the 10-count figure for this version. Each ball is worked into the reachable corners of a filter compartment or set among the decorations in the tank.

Does it suit your tank?

Check the tank size against the dose before ordering. At one Regular ball per 2–5 gallons, 10 balls cover roughly 20 to 50 gallons, and a smaller tank can use part of the pack and keep the rest. A saltwater tank falls outside the stated use, since the manufacturer names freshwater community setups, nano tanks, betta aquariums and shrimp tanks. Source-water hardness and the conditions in the aquarium are the two variables the manufacturer names when adjusting the dose, so a hard-water tank may call for fewer balls than a soft-water one.

Calcium and trace elements in the balls

The balls carry calcium and more than 30 trace elements, and the manufacturer describes them as a slow-release mineral medium. Those elements enter the water gradually as the balls sit in it, which is why the pack is dosed by ball count rather than by a liquid measure.

What the balls do in the aquarium

Mineral content leaches out of the balls over time instead of all at once. The balls themselves wear down as this happens, so a ball in service for months becomes smaller than it was when it went in.

Regular against Large, and the combo packs

Regular balls measure about 1 cm and Large balls about 2.5 cm, and the two sizes differ in their dosing. The manufacturer's figure for a Large ball is one per 5 gallons, while a Regular ball serves 2–5 gallons. The 10 Combo holds 5 Regular and 5 Large balls, and the 20 Combo holds 10 of each.

Which points should I confirm before ordering?

How much water does one ball treat?

The manufacturer's direction is approximately one Regular ball per 2–5 gallons, so a 10-ball pack treats about 20 to 50 gallons in total.

Where do the balls go?

They are placed directly in the aquarium or in the filter compartment.

When should the balls be replaced?

The manufacturer suggests replacing them approximately every 3 months as needed.

What is in the 20 Combo?

The 20 Combo contains 10 Regular balls and 10 Large balls.

Can the dose be changed?

Yes. According to the manufacturer, you may adjust the dosage to suit the hardness of your source water and the conditions in the aquarium.
