08-08-2025Compared to other products on the market, I think this is the best. Very cost-effective for the amount of treatment that you are instructed to use. The health of my fish, the quality of the water, and the clarity are awesome. I can treat the tank just before adding tap water and I've never had a problem with the health of my fish after a water change.

08-08-2025The best conditioner and a real life saver. An absolute must if you're going to do a fish in cycle. I will always use this. It does have a bit of a smell but honestly it's worth dealing with.

08-08-2025Seachem Prime is a fantastic water conditioner and offers great value for the price. It’s very concentrated, so it treats a lot of gallons with just a small amount, making it last a long time. The only tricky part is dosing for smaller tanks since it’s so concentrated, I had to use a syringe to ensure I was adding the right amount. But once you get the hang of it, you're set.
Technical Specifications
About this item POWERFUL TREATMENT: Seachem Prime is a complete and concentrated conditioner for both freshwater and saltwater fish tanks, working hard to remove chlorine and chloramine. REMOVER: Seachem Prime immediately and permanently removes chlorine and chloramine, successfully allowing the bio filter to remove ammonia, nitrite, and nitrate while they are detoxified for 48 hours. DETOXIFIER: Seachem Prime effectively detoxifies ammonia, nitrite, and heavy metals found in the tap water at typical concentration levels, providing a ideal environment for your betta, tetra, or other fish. USE: Use 1 capful (5 mL) of Seachem Prime for each 200 L (50 US gallons) of new or replacement water. For best results, add Seachem Prime to new water first. For exceptionally high chloramine concentrations, a double dose may be used safely. For smaller volumes, use 2 drops per gallon. SAFETY: In case of an emergency, the 5x dose of Seachem Prime may be used for both ammonia and nitrite. Use a ½ dose if the water temperature is > 30°C (86°F) and chlorine or ammonia levels are low.
