Brightwell Aquatics MicroBacter Purple M (500ml)

Brightwell Aquatics MicroBacter Purple M (500ml) is a premium, shelf-stable live bacteria supplement specifically formulated for marine and reef aquaria. At its core is Rhodopseudomonas palustris, a powerful Purple Non-Sulfur Bacterium (PNSB) that acts as a natural biological workhorse to consume excess nutrients, break down organic waste, and biologically fortify your reef.

Key Features & Benefits

Nutrient Control: Rapidly reduces nitrates, phosphates, and ammonia while breaking down detritus, sludge, and uneaten fish food.
Dual-Zone Activity: These photosynthetic microbes are adaptable, thriving in both aerobic (oxygen-rich) and anaerobic (low-oxygen) zones, meaning they actively clean your main display, deep sand beds, and refugiums alike.
Coral Nutrition: Acts as a nutritious live food source that can be directly uptaken by corals, sponges, and other filter-feeding invertebrates to improve vitality and coloration.
Microbiome Support: Outcompetes nuisance algae, diatoms, and cyanobacteria, and serves as an excellent tool in dinosaur-fighting ("Dino") treatment protocols.
Shelf-Stable: Unlike many live bacterial cultures, it requires no refrigeration and is safe to use with automatic dosing pumps.

Important Usage Notes

Color Expections: Do not be alarmed if the liquid inside is not purple. Brightwell Aquatics cultures this strain aerobically for maximum stability, meaning it will arrive as a cream or tan color in the bottle. It may turn a magenta or purple hue once it settles into the low-oxygen pockets of your aquarium.
Contamination Prevention: If you use a pipette or syringe to measure your dose, clean it thoroughly with purified water before inserting it back into the bottle to prevent cross-contamination.

Standard Dosing Guidelines

Always shake well before use and consider turning off your protein skimmer or UV sterilizer for a short period after dosing to allow the bacteria to settle.
