Probiotic Protection

Microbial Biosecurity for Aquatic Systems

An eight-strain microbial formulation for supporting biological balance, competitive exclusion and system resilience in aquariums, ponds, tanks, RAS and biofloc systems. It is a biological supplement — not a chemical or veterinary treatment.

PMX-8 is formulated to manage biological balance across the full system — not a chemical treatment. Natural compounds, competitive exclusion, biological interaction and nutritional support work together as part of a normal maintenance program alongside filtration, aeration and water testing.
The microbial consortium

Eight strains. Every one named.

Bacillus subtilis

Competitive exclusion and organic-waste degradation through a broad enzyme profile. A foundational workhorse strain for biological balance programs.

Key metabolites: surfactin, fengycin, iturin A, bacillomycin D (lipopeptides); difficidin, bacilysin, subtilin; protease, amylase, lipase and chitinase activity.

Bacillus licheniformis

Competitive exclusion and enzyme production, with strong biofloc association. Well suited to high-density and biofloc systems.

Key metabolites: bacitracin and lichenysin (biosurfactant); protease including keratinase, amylase and lipase activity.

Bacillus amyloliquefaciens

Competitive exclusion and substrate colonisation. Supports beneficial biofilm establishment on system surfaces.

Key metabolites: surfactin, fengycin, iturin and bacillomycin; protease, amylase, cellulase and lipase activity.

Bacillus velezensis

Lipopeptide production for broad biological activity within the microbial community.

Key metabolites: surfactin, fengycin and iturin; polyketides including bacillaene and macrolactin; protease, amylase, lipase and cellulase activity.

Paenibacillus polymyxa

Natural compounds and niche colonisation. A documented part of the blend's biological-support profile.

Key metabolites: polymyxins (including colistin), paenibacillin and fusaricidins; amylase, protease, cellulase, lipase and xylanase activity.

Bdellovibrio bacteriovorus

A naturally occurring predatory bacterium included for biological interaction within Gram-negative bacterial populations.

Key activity: hydrolytic enzymes including proteases and lipases; predatory life cycle within Gram-negative bacterial populations.

Streptomyces hydrogenans

Natural metabolites with broad biological activity. An Actinomycete included for its secondary-metabolite profile.

Key metabolites: streptcytosines A–C; complex secondary metabolites including polyketide-type compounds; cellulase, xylanase, chitinase and protease activity.

Marine Rhodotorula

Nutritional support through astaxanthin and beta-glucan — a marine yeast included for its nutritional profile.

Key metabolites: astaxanthin and other carotenoids; beta-glucans; B vitamins; lipase and protease activity.

Protection architecture

Four modes of action

Natural compounds

Streptomyces and Bacillus metabolites contribute the blend's natural-compound profile.

Competitive exclusion

Six spore-forming Bacillus strains colonise available niches in the gut, water column, biofilms and substrate.

Biological interaction

Bdellovibrio bacteriovorus, a naturally occurring beneficial bacterium, provides biological interaction within Gram-negative populations.

Nutritional support

Marine Rhodotorula yeast provides astaxanthin and beta-glucan as nutritional support.

PMX-8 use rates

PMX-8 application rates per label directions (1 scoop = 1 g)
Target concentration PMX-8 per 1,000 L PMX-8 per 100 L Cliq-dose reference
5,000 CFU/ml (maintenance) ~50 mg ~5 mg 1 cliq per 1,000 L
10,000 CFU/ml (heavy load) ~100 mg ~10 mg 1 cliq per 500 L
50,000 CFU/ml (standard) ~500 mg ~50 mg 1 cliq per 100 L

Frequently asked questions

PMX-8 questions

What is PMX-8?

PMX-8 is an 8-strain probiotic protection powder intended to support biological balance in aquariums, ponds, tanks, RAS and biofloc systems. It manages biological balance — it is not a chemical treatment.

How many strains and what viable count are listed?

PMX-8 is listed with 8 named strains and a total viable count of 1 × 10¹¹ CFU/g. Follow the current package directions.

How is it applied?

Apply directly to water — it can also be mixed into feed. Apply once weekly and maintain active aeration during application. See the use-rate table above and the current package label.

Can it replace my filter or water testing?

No. A microbial supplement does not replace suitable filtration, aeration, water testing, quarantine, water changes or responsible stocking and feeding practices.

How should it be stored?

Store sealed in a cool dry place away from direct sunlight. Not for human consumption — avoid inhaling dust. Keep out of reach of children.

Not sure which support your system needs?

Send us the system type, water volume, livestock, temperature and recent water-test results. We can help you work through the biological support options.
