Overview

Nearly all pet aquatics companies manufacture a product that removes chlorine. None of those, however, can compare in quality, concentration, or effectiveness to Seachem’s flagship product: Prime®. Prime® is the complete and concentrated conditioner for both fresh and saltwater. Prime® removes chlorine, chloramine and detoxifies ammonia, nitrite, and nitrate. It is non-acidic and will not impact pH. A further bonus for the reef hobbyist—Prime® will not over-activate skimmers.

Prime® is up to 5x more concentrated than competing products and is the second most concentrated dechlorinator on the market only after our own aquavitro® alpha™.

Prime® may be used during tank cycling to alleviate ammonia/nitrite toxicity. It contains a binder which renders ammonia, nitrite, and nitrate non-toxic, allowing the biofilter to more efficiently remove them. It will also detoxify any heavy metals found in the tap water at typical concentration levels. Use at start-up and whenever adding or replacing water. When transporting or quarantining fish, use Seachem StressGuard™. When adding new fish, use Stability®. Both are ideal for use with Prime®.

Directions

Use 1 capful (5 mL) for each 200 L (50 US gallons) of new water. For smaller volumes, please note each cap thread is approximately 1 mL. May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. Sulfur odor is normal. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite in an emergency, up to 5 times normal dose may be used. If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose.

FAQ

A: Prime® has a very distinct odor that is similar to sulfur which is completely normal.

A: The presence of small black specks occasionally occurs and is normal.

A: A Nessler based kit will not read ammonia properly if you are using Prime®... it will look "off scale", sort of a muddy brown (incidentally a Nessler kit will not work with any other products similar to Prime®). A salicylate based kit can be used, but with caution. Under the conditions of a salicylate kit the ammonia-Prime® complex will be broken down eventually giving a false reading of ammonia (same as with other products like Prime®), so the key with a salicylate kit is to take the reading right away. However, the best solution ;-) is to use our MultiTest™ Ammonia kit; it uses a gas exchange sensor system which is not affected by the presence of Prime® or other similar products. It also has the added advantage that it can detect the more dangerous free ammonia and distinguish it from total ammonia (total ammonia is both free ammonia and non-toxic ionized forms of ammonia).

A: Prime® works by removing chlorine from the water and then binds with ammonia until it can be consumed by your biological filtration (chloramine minus chlorine = ammonia). The bond is not reversible and ammonia is still available for your bacteria to consume. Prime® will not halt your cycling process.

I am going to assume that you were using a liquid based reagent test kit (Nessler based, silica). Any type of reducing agent or ammonia binder (dechlorinators, etc) will give you a false positive. You can avoid this by using our MultiTest™ Ammonia kit (not affected by reducing agents) or you can wait to test, Prime® dissipates from your system within 24 hours.

A: The detoxification of nitrite and nitrate by Prime® (when used at elevated levels) is not well understood from a mechanistic standpoint. The most likely explanation is that the nitrite and nitrate is removed in a manner similar to the way ammonia is removed; i.e. it is bound and held in a inert state until such time that bacteria in the biological filter are able to take a hold of it, break it apart and use it. Two other possible scenarios are reduction to nitrogen (N2) gas or conversion into a benign organic nitrogen compound.

I wish we had some more "concrete" explanation, but the end result is the same, it does actually detoxify nitrite and nitrate. This was unexpected chemically and thus initially we were not even aware of this, however we received numerous reports from customers stating that when they overdosed with Prime® they were able to reduce or eliminate the high death rates they experienced when their nitrite and nitrate levels were high. We have received enough reports to date to ensure that this is no fluke and is in fact a verifiable function of the product.

A: Prime® can be dosed every 24-48 hours.

A: Prime® does not remove ammonia, nitrite, or nitrate from the system. It simply binds with those compounds making them harmless to the inhabitants and still bioavailable to the beneficial bacteria.

A: Prime® will bind up those compounds for up to 48 hours. If they are still present after that time frame, they are released back into the water, unless Prime® is re-dosed accordingly. Also, if your ammonia or nitrite levels are increasing within a 24-hour period, Prime® can be re-dosed every 24 hours.

A: If your ammonia or nitrite levels are above 2 ppm, you can safely use up to 5 x the recommended amount.

A: No, as long as Prime® has been stored properly, it will last indefinitely.

A: Prime® can vary in smell based on the parameters in the warehouse during the time of manufacture. It does normally smell of Sulfur, but we have extensively tested the product and found that the difference in scent does not in any way effect how the product functions. It is still perfectly safe to use!

Big Investment for a Lifetime of Quality
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
Several reviews mentioned a smell lingering with the sheepskin even after being unpacked a few days. I did notice the smell when I unpacked it, but I would expect a slight odor from such an item. It was not overpowering and is completely gone after one month of having it laid out on a chest in our bedroom. It is very functional, can be sat on, knelt on, etc, but is easily brushed off and looks great! The quality is very good…someone in my family is on it every night, and we have experienced no shedding whatsoever. Although the price is a big investment initially, I believe the quality is worthy. We plan to enjoy this beautiful sheepskin for a lifetime!

Love it, but terrible smell at first
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
Really soft & my dog loves it. I used it as a throw over my couch for decor. The smell when I took it out of the package was probably one of the worst smells I’ve ever smelled. Like old broccoli or something. I left it outside to air out all day and that was gone.

Not premium quality! I've seen actual authentic ones before.
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
Despite all the positive reviews, I believe this product is subpar. There are genuine sheep skin Hydes but this product is NOT it. There is no leather embossing showing authenticity, and many signs of strong chemical treatment. Smell is lingering and I've aired them for over two days. Not very comfortable since the fur is very thick and coarse, you would expect it to be softer for the price as well. Not premium quality. I ordered this for my children to sleep on at long evening Church services but now I will look to more niche sellers for a higher quality product.

Great product: thick and cozy
Size: Single Pelt/2 ft x 3 ft, Color: Natural (Ivory Whiite)
This is a lovely, thick sheepskin. I’m using it to drape over a chair. It’s very soft. The color is a natural white. Arrived quickly. The price was great for such a wonderful sheepskin.
