Red Sea Reef Mature Pro Kit
A staged 21-day program that matures a new marine system before livestock goes in. The Red Sea Reef Mature Pro Kit seeds nitrifying and de-nitrifying bacteria and supplies the supplements that carry a new tank through cycling to a stable, algae-resistant baseline — one kit treats systems up to 250 L (65 US gal).
Key features
- Four-bottle staged program — Nitro Bac, Bacto-Start, NO3:PO4-X and KH-Coralline Gro, dosed on a set 21-day schedule.
- Treats up to 250 L (65 US gal) per kit — larger systems need multiple kits dosed to the same schedule.
- Cost per litre of system treated: $0.24 — working from the 250 L one kit covers, at the current price.
- Seeds the biofilter directly — Nitro Bac carries live nitrifying and de-nitrifying bacteria spores onto rock, substrate and bio-media rather than relying on ambient colonisation.
- Structured dosing removes the guesswork from the first weeks of a new system, including a scheduled 5% water change partway through the program.
What's in the kit
| Bottle | Role |
|---|---|
| Nitro Bac | Concentrated blend of nitrifying and de-nitrifying bacteria spores, seeded onto rock, substrate and bio-media |
| Bacto-Start | Balanced nitrogen and phosphorus components that simulate aquarium waste, feeding the developing bacterial colony |
| NO3:PO4-X | Carbon and organic-bonded element complex for nitrate and phosphate control |
| KH-Coralline Gro | Marine buffer complex of carbonate buffers and potassium, fortified with minor and trace elements including iron |
Kit total: 4 x 100 mL (3.38 fl oz) bottles.
Dosage and directions
The program runs over 21 days: an initial bacterial and supplement dose on day 2, daily NO3:PO4-X dosing with staged bacterial top-ups through days 3–6, a first 5% water change and continued supplementation from day 7, daily maintenance doses through days 8–20, and a final water change with reduced NO3:PO4-X on day 21. Follow Red Sea's printed program for exact daily volumes against your system size — don't add other supplements or livestock until the program says it's time.
Suitable for, and not suitable for
- Suitable for: cycling and biologically maturing a new marine or reef system before stocking.
- Not suitable for: established, already-cycled systems — this is a startup program, not an ongoing water-care routine.
Care and maintenance
Test pH, KH, ammonia, nitrite and nitrate through the program to confirm it's tracking as expected, and top up daily evaporation with RO/DI water so dosing volumes stay accurate.
Warranty and delivery
Covered by Red Sea's manufacturer warranty against defects, in addition to your rights under Australian Consumer Law. Standard shipping across Australia.
Goes well with
- Red Sea Marine Care Multi Test Kit — you'll need to track pH, KH, ammonia, nitrite and nitrate through the 21-day program, and this covers the parameters the schedule checks against.
Common questions
How many kits do I need for my tank?
One kit treats up to 250 L (65 US gal). For a larger system, use multiple kits and dose them together on the same schedule rather than stretching one kit further than its rated volume.
Can I add fish or coral partway through the program?
No — the schedule is built around an unstocked system. Wait until the full 21-day program, including the final water change, is complete before stocking.
Do I need to change any water during the program?
Yes — a 5% water change partway through, and another at the end of the 21 days.
Is this cheaper than buying the bacteria and buffer products separately?
At $0.24 per litre of system treated, the kit format bundles the four staged products at one price. If you already have KH buffer or bacteria products from another maturation run, buying only what you're missing may work out cheaper for a small top-up — the kit's value is the full staged program, not the individual bottles.
