In saltwater aquarium keeping, maintaining the chemical balance of water is crucial for the health and aesthetics of the entire ecosystem. One of the challenges facing aquarists is controlling algae growth, which is often directly related to levels of certain minerals in the water. Below are minerals whose excess can contribute to excessive algae growth in a saltwater aquarium.
Nitrogen (N) and Phosphorus (P)
- Nitrates (NO3) and Phosphates (PO4) are the main nutrients that stimulate algae growth. Excess of these substances often comes from food residues, decomposition of organic matter, and inadequate filtration. High levels of nitrates and phosphates can lead to the rapid development of filamentous algae, diatoms, and cyanobacteria.
Iron (Fe)
- Iron is a crucial trace element utilized by algae in the process of photosynthesis. Its excess, although less common, can promote the growth of certain types of algae, especially in the presence of high phosphate levels.
Silicon (Si)
- Silicates are particularly important for the growth of diatoms, which are a type of algae. High concentrations of silicon can come from RO water, certain types of sand, rocks, as well as some aquarium additives.
Manganese (Mn) and Molybdenum (Mo)
- Similarly to iron, manganese and molybdenum are trace elements utilized by algae in their biochemical processes. An excess of them can promote algae growth.
Control of Mineral Levels
- To prevent excessive algae growth, it is recommended to regularly test the water in the aquarium to monitor the levels of these minerals.
- Effective filtration and regular water changes can help maintain these levels within a safe range.
- Limiting the amount of feeding and ensuring the quality of food can also reduce the impact of nitrates and phosphates on algae growth.
Summary
Managing mineral levels in a saltwater aquarium is crucial for preventing excessive algae growth. Regular water tests, proper filtration, balanced feeding, and the use of methods to reduce specific minerals are important for maintaining a healthy and beautiful saltwater aquarium.

Marek Protasewicz
Reefkeeping has been my passion for over 10 years now. I love learning. The hobby has taught me many valuable lessons, patience being the best example. Combining work and passion is my path. I run Crazy Coral, a marine aquarium shop, for a number of years. Building this business from the scratch I learnt from my own mistakes at a heavy cost.
Later I managed a project aimed at development of methods for quick growth of Corals in non-natural conditions. The project was carried out by Get Sales, Poland. Presently, I am responsible for distribution strategy at Reef Factory, of which I am a co-founder. The company produces smart devices for marine aquaristics. The last projects I have been involved in are Social Reef and ReefPedia.
