Seachem SureStart bundles three of Seachem's most useful water-care products into a single starter kit. You get a 100 mL bottle of Prime to neutralize chlorine, chloramine, and heavy metals at every water change, Stability to seed nitrifying bacteria for a smooth fishless or fish-in cycle, and Pristine to digest the organic sludge that accumulates between cleanings. It's the easy "buy this on day one" pack for a new tank, and the cleanest restock for an established one. Browse our additives and supplements collection when you're ready to refill in full size. What's Inside Seachem Prime (100 mL): the gold-standard water conditioner. Removes chlorine and chloramine, detoxifies ammonia, nitrite, and nitrate, and binds heavy metals. One drop per 2.5 gallons. Seachem Stability (100 mL): live nitrifying and aerobic bacteria that establishes the biofilter. Safe to dose with fish in the tank from day one. Seachem Pristine (100 mL): heterotrophic bacteria that breaks down sludge, fish waste, and uneaten food, reducing the organics that fuel algae. Who It's For New aquarists who want one box that covers conditioning, cycling, and waste control without picking products one at a time. New tanks (5 to 60 gallons) where 100 mL bottles last through the initial cycle and the first few water changes. Gift or starter add-on for someone setting up a betta tank, planted nano, or first community aquarium. Travel or backup kit for established tanks, so you always have a small bottle of each on the shelf. How to Use Together Fill the tank. Dose Prime first to neutralize chlorine, chloramine, and heavy metals from tap water. One drop per 2.5 gallons, or 5 mL per 50 gallons. Seed the biofilter. Dose Stability daily for the first 7 days, then weekly, to build the nitrifying bacteria colony that will eventually handle your fish load. Keep waste in check. Dose Pristine weekly to digest the organic sludge that builds up in substrate, rock, and filter media. On every water change going forward: Prime in the new water, Stability if you added fish or disturbed the filter, Pristine for ongoing waste control.

Prime, Stability, and Pristine all work in freshwater and saltwater tanks at the labeled dose, so the same kit can start a betta nano or a reef-ready 40 gallon. Do I need anything else to cycle a new tank?This pack covers conditioning, nitrifying bacteria, and waste digestion. You'll also want a water test kit to track ammonia, nitrite, and nitrate as the cycle progresses. Can I add fish on day one?Stability is designed to be safe for fish-in cycling, but pace yourself. Add a small bioload first, test daily, and only increase stocking once ammonia and nitrite read zero. How long does the pack last?For a 20-gallon tank, expect roughly 1 to 2 months on Prime, 2 weeks of Stability dosing through the cycle, and 2 months of weekly Pristine. Restock individual full-size bottles once you outgrow the kit. Is Pristine the same as a sludge remover?Pristine uses heterotrophic bacteria to digest organic waste rather than enzymes alone. It works in the substrate, rock, and filter, not just the water column.
