Continuum ULNS Phos 500ml for Phosphate Limited Aquaria

ULNS Phos is a complex inorganic phosphorus source from Continuum Aquatics, designed for ultra-low nutrient systems (ULNS) that are phosphate limited. It promotes natural nitrogen uptake and nutrient control, and provides an important nutrient source for nitrification and denitrification as well as proper nutrient assimilation.

ULNS systems rely on bacterial management of nitrogen in a balanced carbon and phosphorus environment. This allows rapid uptake of excess dissolved organic compounds and converts them to bacterial biomass, which can then be removed by protein skimming. For this recycling to work, nitrogen, phosphorus and carbon all need to be present together. If nutrient levels are not kept adequate in a ULNS system, bleaching or coral tissue degradation may occur.

Continuum recommends using ULNS Phos with BacterGen.M, BacterGen.MD or BacterClean.M to keep microbe levels at their best, along with Reef Micro.Fuel to replenish and accelerate the growth of aerobic, anaerobic and facultative bacterial populations.

Recommended for advanced hobbyists running phosphate limited, ultra-low nutrient reef aquariums. Supplied in a 500ml bottle.
