Pond Care & Maintenance
Pond Care & Maintenance — Keep Your Pond Clear, Balanced and Healthy All Year Round
A healthy pond doesn’t just happen — it needs the right products at the right time. Whether you’re battling green water, clearing string algae, building up beneficial bacteria after winter, removing sludge from the bottom, or vacuuming out debris before summer, this is where you’ll find everything you need.
We are authorised Australian resellers of BBA Biosolution PurePond, PondMAX and OASE — three trusted brands covering the full spectrum of pond care and maintenance. All products ship nationally to NSW, QLD, VIC, SA, WA and NT.
BBA PurePond — Beneficial Bacteria & Targeted Treatments
The BBA Biosolution PurePond range is a professional line of beneficial bacteria products, water conditioners and targeted treatments using named proprietary bacterial strains. Developed for pond and water feature environments, the range covers all key pond health challenges:
| Product | What it targets |
|---|---|
| 4-in-1 Maintenance | All-season biological balance — bacteria, enzymes, water conditioner and fish probiotic in one weekly dose |
| Cold-Active Bacteria Powder | Winter pond maintenance — psychrophilic bacteria active below 10°C for Melbourne, Canberra and alpine areas |
| Algae Blaster | Reduces the nutrients that fuel algae growth |
| Sludge Away | Breaks down bottom sludge using facultative anaerobic bacteria (BBA AnaeroPro-411) |
| Bio-Flocculant | Clears suspended particles and green water — follow up with 4-in-1 Maintenance |
| Beneficial Bacteria Liquid | Fast-acting liquid for new ponds, filter re-seeding and ongoing biological support |
| Tannins Clear | Removes tea-coloured water caused by leaf tannins using tannase-producing bacteria |
| Fish Vigor | Fish health probiotic — supports immune function and reduces stress |
| BioBoost Water Conditioner | Dechlorinates tap water and supports biological filtration during water changes |
PondMAX — Australian-Designed Pond Treatments
PondMAX is an Australian brand designed specifically for Australian pond conditions. The range offers targeted, easy-to-use treatments for the most common pond problems — all safe for fish, aquatic plants and wildlife when used as directed:
| Product | What it targets |
|---|---|
| BactiMAX+ Natural Water Clarifier | Naturally clarifies water using beneficial bacteria — reduces sludge, ammonia, nitrates and phosphates |
| CleanMAX+ Algaecide Pond Cleaner 940ml | Targets algae growth and cleans pond surfaces — concentrated formula |
| ClearMAX Flocculant 470ml | Clumps suspended particles causing cloudy or green water so your filter can remove them |
| Pond Clarifier Treatment 180g | Concentrated beneficial bacteria powder — recharges filter and reduces pond sludge and surface sedimentation |
| String Algae Treatment Powder | Naturally clears blanket weed and string algae using unique plant extracts — harmless to aquatic plants |
| Pond Treatment 3 in 1 | Treats blanket weed, green water and sludge simultaneously using beneficial bacteria |
OASE AquaActiv — German-Engineered Water Treatments
OASE is one of the world’s leading pond equipment manufacturers, and the AquaActiv treatment range is engineered to the same standard as their filters and pumps. Two targeted treatments are available:
| Product | What it targets |
|---|---|
| AquaActiv PhosLess Direct 500ml | Removes excess phosphate — the primary nutrient driving algae blooms. Reduces phosphate below the algae growth threshold (0.035 mg/l). Not for use in ponds containing sturgeons. |
| AquaActiv OptiPond 500ml | Stabilises pond water chemistry — binds ammonia and ammonium, stabilises pH and protects fish through seasonal transitions. Recommended at the start and end of the pond season. |
Pond Vacuums — OASE Pondovac & PondMAX
Remove sludge, debris and organic waste from the pond floor without draining the pond. A pond vacuum is one of the most effective tools for reducing the nutrient load that feeds algae — and works alongside your water treatments to deliver lasting clarity. We stock both OASE and PondMAX vacuum models to suit different pond sizes and budgets:
| Model | Best suited to |
|---|---|
| OASE Pondovac Classic | Smaller ponds and regular maintenance — reliable entry-level OASE vacuum |
| OASE Pondovac 4 | Mid-size ponds — continuous discharge system for uninterrupted vacuuming |
| OASE Pondovac 5 | Large ponds and koi ponds — high-performance continuous discharge, extended reach |
| PondMAX PV30HD Pond Vacuum | Medium ponds — powerful standalone vacuum unit, great value alternative to OASE |
| PondMAX Pro Pond Vacuum — Super Sucker | Spot cleaning and smaller ponds — compact, hose-powered vacuum head for quick debris removal |
Not sure where to start? For most ponds, the fastest path to clear water is: (1) vacuum out sludge and debris, (2) apply a flocculant to clear suspended particles, (3) dose with beneficial bacteria to restore biological balance and prevent recurrence.
