Seachem Reef Advantage Calcium

Seachem Reef Advantage Calcium is used to restore and maintain calcium levels in aquariums to support coral growth while also providing magnesium and strontium in proportionate amounts.

  • Concentrated, powder ionic calcium
  • Maintains magnesium and strontium
  • Can be added directly to aquarium

Seachem Reef Advantage Calcium is a non-caustic (pH 8.3–8.6) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health.

Reef Advantage Calcium™ also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while maintaining calcium. Unlike limewater (kalkwasser), Reef Advantage Calcium™ does not have a caustic pH and will not deplete magnesium. Used as directed, it will not deplete alkalinity.

Directions

BEGINNER: Use 5 g (1 level teaspoon) per 150 L (40 gallons) twice a week. Dissolve in at least 250 mL (1 cup*) of freshwater. Check calcium every 2 weeks and adjust amount or frequency accordingly.

ADVANCED: Check calcium level, then follow addition regimen above until calcium is adjusted to 380–420 mg/L. Each 5 g/150 L will raise calcium by about 12 mg/L. Quantity or frequency can be adjusted, but do not exceed 10 g/150L per day. Thereafter, use as required to maintain calcium.

EXPERT: After determining the calcium consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: m=vc/400 (m=grams to add to top off water, v=volume of tank in liters, c=amount to raise calcium in mg/L). For example, if you want to raise calcium by 25 mg/L in a 200 liter tank, then you would add 200x25/400=12.5 g into the top-off water. [For reference: 1 gallon*=3.8 liters, 5 g=1 teaspoon*]. HINTS: If used with Reef Calcium™, it is not necessary to exceed 380 mg/L total calcium. Use Reef Status™: Calcium to measure calcium.

DO NOT OVERDOSE: Excess calcium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if calcium & carbonate additives are added on alternate days or at least 30 minutes apart.

Transformative
Format: Paperback
I rarely write reviews, but this book truly deserves it. From the moment I started reading, I realized this was not just another edition of scripture—it felt like stepping into a deeper, more complete spiritual library. The inclusion of texts like Enoch and Jubilees adds layers of meaning that are often missing from more familiar versions. I found myself pausing often to reflect because the content is so rich and thought-provoking. The large print is an absolute blessing. I spend a lot of time reading each day, and this format has significantly reduced eye strain. It allows me to fully immerse myself without discomfort, which is something I didn’t realize I needed until I experienced it. What I appreciate most is how this book bridges curiosity and faith. It invites you to explore, question, and learn while still feeling grounded. Whether you’re a long-time student of scripture or just beginning your journey, this edition offers something meaningful. It has quickly become one of the most important books in my personal library.

Love these for my classroom!
Posters go great with my book! I use them as a visual as my class works through each of the love languages lessons. Order arrived on time. Update: I've used these posters for years now and they are great. I recommend laminating them so you can keep reusing them over the years. Two thumbs up!
