Important Information

Directions
Use 1 capful (5 mL) for each 200 L (50 gallons*) of new water. This removes approximately 1 mg/L ammonia, 4 mg/L chloramine, or 5 mg/L chlorine. For smaller doses, please note each cap thread is approx. 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.

When I moved into my new house, I knew that meant setting up a new tank. There was no way I would be shipping all of my old tanks and fish to the new house, so I would have to start over. Obviously, I was a bit nervous about this. I had worked hard on my old tanks, getting the water to just the right chemical levels and temperatures. I was unsure how long it would take me to condition the new tanks in the same way.

In my old tanks, rocks and pebbles covered the bottom of the aquarium. I wanted to go for a new look, so I began looking online for some greenery to spice up the new aquariums. I found the LUFFY balls Luffy balls, and I knew that they were exactly what I was looking for. They gave the tank a fresh, clean appeal that I absolutely loved! However, with fish and live plants in my new tanks, I knew I had to be careful about watching my chemical levels in the water. I filled the tank with tap water, and I ordered this primer to take out any harmful chlorine or other metals. With just ONE CAP the water was ready instantly for both my fish and my plants, I was amazed!

Now, I've been using this product for quite a while, and I know the ins and outs of all of it.

- Just a few drops will clear up an entire tank. It doesn't take much to make a difference.
- This product will keep your fish and plants safe from harmful chemicals.
- Even shrimp, which are more sensitive to chemicals than fish are safe with this formula.
- This product works instantly.
- Could also be used in small fish ponds.

From Cichlids to Fancy Goldfish I've been keeping fish for 30+ years.Just about every major manufacture and boutique specialty company has a water conditioning and treatment product.I can't say I've tried them all, but close too it. Some products have at the least, minimal effectiveness while others can be potentially dangerous.

An example would be Stress Coat which has binding sugar strands in the Aloe. This isn't a problem unless one of your fish has a small scratch or wound.The sugar feeds the bacteria which can lead to major infection and dire consequences.I've been using Amquel for years and it's a fine conditioner, excellent at removing chlorine, and Chloramines, but like all these products - they come with limitations.

Well, with one exception and that's Prime by Seachem.

A few months ago, I decided to give it a try, and haven't looked back since. Prime doesn't just remove the chlorine and Chloramine it does much more:

* Detoxifies any and all heavy metals in your tap water

(you can call your water company directly for a list of them and PPM)

* Neutralizes Ammonia

* Neutralizes Nitrite

* Neutralizes high Nitrate to non toxic levels

* Removes toxic gases

* Will not foam or change PH

* Helps regenerate natural slime coat

Since using Prime, I've seen a dramatic improvement in all of my fish. In 2010 one of tanks was hit with the dreaded and rare Toxic Tank Syndrome - within 48 hours I had lost nine gorgeous fish - except for one survivor, a single Broad Tail Nymph.Since that ordeal, "Roxy" became a bottom dweller spending most of her time laying in a corner. Treatments were conservative, but nothing worked.

I usually don't write reviews, but I did want to take the time to recommend this product. I have been keeping fancy goldfishes for over ten years now and finding the right tap water conditioner had always been a headache for me. I have tried most of the popular products on the market and they have always given me either mixed results or no results at all. Too often, I've had the fish die on me after a water change. However, when someone recommended the Prime water conditioner to me during a visit to the pet store, my problem was solved. I have used this product for a few years now and never since had any more fish die after a water change. I sincerely believe this is the most effective all-in-one solution on the market and for regular fish keeping, this is the only water conditioner one really needs.

In my opinion, SeaChem's Prime is the best water conditioner on the market. I've tried a few of them and Prime does the best job. It removes chlorine/chloramine and other toxic metals from water instantly. Plus, as little as literally ONE drop treats a gallon of water. I have a total of 115 gallons of water in my 3 tanks. I perform 50% weekly water changes in all of the 3 tanks. To give you an idea of how economical Prime is, I've had a 250 mL bottle of it for more than a year. Only a few dollars' worth will treat hundreds of gallons of water. And as I've mentioned above, I perform 50% weekly water changes for my 115 gallons of water. Now, that's what I call a really great product. Highly recommend it to any serious fish keepers :o)
