SPS & LPS Corals

SPS corals require stable environments with good water quality, high lighting, and water flow. Here are some tips for keeping SPS corals:

Water quality
SPS corals need clean water with good nutrient levels. You can use fish excrement, which contains nitrates and phosphates, to help the coral. You should also test your water regularly to find stable parameters like salinity, nitrate, magnesium, and calcium.
Lighting
SPS corals need strong lighting, which can help them grow small polyps. You can use LED, T5s, or halide lighting, or a combination of light sources. Depending on the coral genus, it will need between 150 and 600 umols of P.A.R. (photosynthetic active radiation).
Water flow
SPS corals need substantial water movement to help deliver nutrients and food to the corals. Random flow is also beneficial, and you can achieve it with a pump that replicates waves moving across a natural reef.
Stability
SPS corals are less forgiving when it comes to things like alkalinity, calcium, and nutrients. You should keep things stable, such as salinity, nitrate, magnesium, and calcium.

You can also try feeding your corals, which can accelerate growth, improve coloration, and raise a coral's ability to tolerate stress.

Some species of SPS corals do better in cooler waters, but most tropical-based species seem to hold up well in tanks that range from 79F to 81F.

LPS Corals

LPS corals, or large polyp stony corals, are generally easy to grow and suitable for beginners. They require moderate to high light levels and moderate flow rates, but some species prefer low light and low flow, while others need more intense lighting and higher flow. LPS corals also require a stable water temperature between 75 and 80 degrees Fahrenheit, with specific gravity levels between 1.023 and 1.025, pH between 8.1 and 8.4, alkalinity between 8-12 dKH, and calcium between 400 and 450 p

Here are some other LPS coral requirements:

Feeding
Feed the corals two to three times a week with protein-rich foods. Feeding can lead to increased growth rates.
Quarantine
Always quarantine new corals before adding them to your main display tank. This can help prevent the spread of disease or parasites to your existing corals.
Room between corals
Provide plenty of room between corals.
Predators
Make sure that you do not have any predators picking on your corals, including pests and fish.

Different LPS coral species have different growth rates and patterns. For example, Microlords, Aussie Lords, is a good beginner coral that needs sufficient lights.
