MicroBacter Purple PNS Bacteria - Brightwell Aquatics

MicroBacter Purple from Brightwell Aquatics puts Purple Non-Sulfur Bacteria to work on nutrient cycling and water clarity, while also supplying a natural food source for corals and inverts. Because no refrigeration is required, it is easy to keep on hand.

Why Choose MicroBacter Purple?

• Live, beneficial bacteria: a diverse, shelf-stable mix of photosynthetic bacteria
• Complements MicroBacter7 and MicroBacter Clean, enhancing microbial diversity and waste breakdown
• Dual aerobic and anaerobic action: supports both oxygen-rich and low-oxygen zones for more complete nutrient processing
• Nutrient control: helps reduce detritus, excess nutrients, and organic waste for a cleaner, more stable aquarium
• Natural coral nutrition: supplies corals, sponges, and filter-feeding invertebrates with a bioavailable food source that Brightwell says supports coloration and growth
• Shelf-stable convenience: no refrigeration required

What Are PNS Bacteria?

PNS bacteria are a group of photosynthetic bacteria that can function in both oxygen-rich and low-oxygen conditions. That flexibility is why Brightwell positions MicroBacter Purple for so many parts of an aquarium, from open water in the display to deeper, oxygen-poor areas of the substrate.

Where MicroBacter Purple Fits in Your System

Brightwell designed MicroBacter Purple for use in:

• Deep sand beds
• Refugiums
• Media reactors
• Display tanks

It is intended to work alongside MicroBacter7 and MicroBacter Clean, so if you already use either product, MicroBacter Purple adds another group of bacteria to your aquarium's microbial community.

Storage and Use

MicroBacter Purple is shelf stable, so you can store it at room temperature without refrigeration. Follow Brightwell Aquatics' label directions for dosing amounts and frequency.
