Seachem 437 Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 500ml Review: Amazing product no issues - This is the only product that we use for our fish tank. We’ve had no issues. No fish passed away in the water changes or anything perfect product for your fishing tank. My tank is only 9 gallons. Review: The best antichlor product. - Ive used several brands of aquarium chemicals and conditioners. Prime is the best Ive found that removes chlorine, chloromine, ammonia and some heavy metals. Its fantastic at doing this. Following the listed dosing instructions seldom leads to any issues. But, the dosing instructions are only estimates as every municipal water system has differing amounts of hazardous chemicals and can even vary hour to hour. You can safely overdose the suggested amount to treat heavily doped city water. Bit if you do overdose too much, and far exceed the amount of chemicals in the water, Prime will tend to go after oxygen in the water too. If you notice the fish at the top gasping for air after adding a large dose of Prime, youve likely overdosed Prime. You can solve this overdose within often minutes by having an air stone bubbling heavily in the tank water. This will usually get enough water and air circulated to get oxygen back into the water within minutes. Frankly most tanks can benefit from an air stone all the time anyway. But if you follow dosing instructions, youll find you can use less Prime than the other brands and save some money while protecting your fish from municipal chemicals. Prime doesnt add slimecoat to the water. So sensitive fish like Cories and Loaches are better served. You can also use Prime to clean filter media recycled with Ammonia. High doses of Prime removes the ammonia solution used to clean. It can be added at each water change or small doses can help alleviate ammonia or nitrite spikes temporarily. It can be purchased in small little 250ml bottles clear up to 2l bottles for ponds or if you use it to detoxiify ammonia soaked Purigen. It does have an expiration date but will isually at last a year or so after bottled. Just be sure its shaken and mixed before applying. Also both in the bottle and when nuetralizing chemicals, it gives off a strong sulphur odor that disipates quickly. Sniffing the bottle could make you sick. You can store it at room temperature but dont let it set out in sunlight or to freeze. This is the most important and reliable chemical treatment I use. And I use it often in my tanks, especialy during water changing days. I usually get 1L or 500ml at a time. If youve only got one small tank, the 250ml size might be better for you. I always keep it on hand. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B010UNMS9M | | Allergen Information | Allergen-Free | | Best Sellers Rank | #11,352 in Pet Supplies ( See Top 100 in Pet Supplies ) #89 in Aquarium Water Treatments | | Brand | Seachem | | Brand Name | Seachem | | Customer Reviews | 4.9 out of 5 stars 2,404 Reviews | | Item Form | Liquid | | Item Weight | 1.3 Pounds | | Liquid Volume | 500 Milliliters | | Manufacturer | Seachem | | Manufacturer Part Number | SE0433 | | Model Number | SE0433 | | Number of Packs | 1 | | Target Species | Fish | | UPC | 000116043304 | | Unit Count | 16.9 Fluid Ounces | ## Product Details - **Brand:** Seachem - **Item Form:** Liquid - **Item Weight:** 1.25 Pounds - **Liquid Volume:** 500 Milliliters - **Manufacturer:** Seachem ## Images ![Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 16.9 fl. oz - Image 1](https://m.media-amazon.com/images/I/81aLONkZHPL.jpg) ## Questions & Answers **Q: Can this product be used in a tank with water snails in it?** A: I am not sure the type of snail you have but I have snails in my 75 gallon discus tank which is fresh water and I have used Prime for many years without problems. **Q: I guess I should have asked if this contains Sulphur , thus the smell, or sulfites of any description?** A: The label states it contains complexed hydrosulfite salts **Q: how long is the expiration date of prime after opening?** A: Am new at the hobby, but i didn’t see in the bottle that has a expiration date.
