## Description

SeachemReef Calcium 500ml

## Features

- CONCENTRATED BLEND: Reef Calcium is a concentrated bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH.
- POLYGLUCONATE COMPLEXACTION: Increases the bioavailability of the calcium, provides a rich source of metabolic energy to help maintain peak coral growth, and it prevents calcium precipitation/alkalinity depletion.
- ORGANIC CALCIUM: Reef Calcium Reef Calcium utilizes a chained organic calcium rather than an ionic calcium.
- USE: Reef Calcium may be used alone to maintain calcium but will provide enhanced levels of coral growth when used in conjunction with an ionic calcium supplement such as Seachem’s Reef Complete or Reef Advantage Calcium.
- DIRECTIONS: Add 1 capful (5 mL) per 80 L (20 US gallons) twice a week. You can increase the amount or frequency based on growth response but do not exceed 3 capfuls per 80 L (20 gallons) per day. Each capful will raise calcium by about 3 mg/L.
