This article provides a detailed overview of AC's Sea Water Series core products, helping you build a stable, pure, and thriving marine ecosystem.

1. Basic Filtration: Marine-Spec Activated Carbon — The Guardian of Pure Water

Why Choose Marine-Spec Activated Carbon?

In reef aquariums, phosphate (PO4) is the number one enemy of corals. Elevated phosphate levels not only inhibit coral calcification but also trigger algae blooms that disrupt the tank's ecological balance. Conventional activated carbon products often contain high phosphate impurities, which can become a source of pollution with long-term use.

Core Advantages of AC Marine-Spec Activated Carbon

AC Marine-Spec Activated Carbon undergoes special activation treatment, with a phosphate leaching level of only 0.0000013g/ml—virtually negligible. Meanwhile, its methylene blue adsorption value reaches 181mg/g, far exceeding standard activated carbon, enabling rapid removal of organic pollutants, residual medications, and yellowing compounds.

Quick Product Specifications:

> Pro Tip: Replace activated carbon every 4-6 weeks to ensure continuous adsorption performance. Rinse briefly with RO water before use to remove surface dust.

2. Biological Filtration: NP-Reducing BioPellets — A Revolution in Nutrient Control

Understanding the Hazards of Nitrate and Phosphate

In closed marine systems, fish waste and uneaten feed continuously decompose, producing nitrate (NO3) and phosphate (PO4). When NO3 exceeds 5ppm or PO4 exceeds 0.03ppm, coral skeletal growth is significantly inhibited, and algae proliferation begins.

How BioPellets Work

AC Marine BioPellets are biodegradable materials that provide an ideal habitat for aerobic microorganisms. When placed in a BioPellet reactor, water flow causes the pellets to tumble, allowing microorganisms to form a biofilm on the surface. These microbes use the pellets as a carbon source while consuming nitrogen (N) and phosphorus (P) from the water, converting nitrates and phosphates into biomass that is ultimately removed by a protein skimmer—achieving permanent nutrient export.

Key Features:

- Efficient simultaneous reduction of NO3 and PO4

- Formation of anaerobic layers promoting denitrification

- Continuous operation with minimal maintenance

- Packaging: 500mL/bottle

> The Science: Biological filtration essentially utilizes carbon dosing to drive the denitrification process. AC BioPellets are engineered with precise degradation rates to ensure optimal carbon supply matching microbial demand, preventing water quality fluctuations from carbon overdosing.

3. Bacterial Cultivation Core: Marine-Spec Bio Block — The Foundation of Nitrification

Critical Criteria for Biological Filter Media

For marine aquariums, biological media must not only provide sufficient surface area for nitrifying bacteria but, more importantly, must not release harmful substances. Traditional ceramic rings and glass rings often contain high levels of phosphates and heavy metals that accumulate as long-term contaminants.

4. Precision Phosphate Control: Phosphate Remover — The Phosphate Eliminator

Emergency Solutions for PO4 Spikes

Even with diligent maintenance, reef tanks occasionally experience sudden phosphate increases—perhaps from contaminants introduced with new corals or overfeeding. In these situations, a fast-acting, efficient, and reusable phosphate removal product is essential.

Technical Highlights of AC Phosphate Remover

AC Phosphate Remover utilizes an iron-based/aluminum-based composite formula with high porosity and specific surface area, achieving a phosphate binding capacity of 1.99mg/g—far surpassing competing products.

Performance Comparison:

Laboratory data demonstrates that under identical conditions, AC Phosphate Remover reduces phosphate to safe levels within 6 hours, while competing products require significantly longer. Even at higher flow rates, it maintains excellent removal efficiency without particle breakdown or failure.

Usage Recommendations:

> ⚠️ Important Note: Monitor pH when using Phosphate Remover to avoid fluctuations from large single-dose applications. Add gradually in batches to slowly reduce PO4 levels.

5. Elemental Supplementation: Activated Calcium Reactor Media & Reef Spec Magnesium Plus — Building Blocks for Coral Skeletons

Coral Calcification and Elemental Balance

Hard corals (SPS) and soft corals (LPS) require substantial calcium (Ca) and magnesium (Mg) to build calcium carbonate skeletons. Natural seawater maintains calcium at approximately 420ppm and magnesium at approximately 1300ppm, with a Mg:Ca ratio of approximately 3:1. Any deficiency or imbalance in these elements will cause growth stagnation or coral mortality.

AC Activated Calcium Reactor Media: The Perfect Partner for Calcium Reactors

AC Activated Calcium Reactor Media is a high-purity media specifically for calcium reactors, treated with advanced activation technology to achieve 35% higher calcium dissolution efficiency compared to conventional media. When used with CO₂ systems, it slowly dissolves to continuously release calcium, magnesium, strontium, potassium, and carbonates.

Three Guarantees:

- ✅ Contaminant-Free: Pure and safe, no impurity concerns

- ✅ Low Phosphate: Virtually phosphate-free, eliminating risk

- ✅ pH Stable: Dissolves steadily in optimal pH conditions

8. Core Principles of Marine Aquarium Maintenance

While using AC Sea Water Series media, adhere to these maintenance principles for long-term coral health:

1. Stability Above All: Corals are extremely sensitive to water parameter fluctuations. Any drastic changes in temperature, salinity, pH, KH, Ca, or Mg can cause stress or mortality. The advantage of AC media lies in their extremely low harmful substance leaching rates, eliminating additional variables.

2. Dual Nutrient Control: Both NO3 and PO4 must be maintained in appropriate ranges (NO3 < 5ppm, PO4 < 0.03ppm). AC BioPellets' simultaneous NP reduction prevents imbalances from controlling only one nutrient.

3. Element Balance Over Absolute Values: Maintaining a 3:1 Mg:Ca ratio with KH stable at 8-12dKH is more important than pursuing high calcium alone. The synergistic release characteristics of AC Calcium and Magnesium media help maintain this balance.

4. Prevention Over Cure: Regularly test water parameters to catch issues early. AC media's premium quality design specifically minimizes "unexpected contamination" incidents.
