Review of Seachem Prime from an Aquarium Enthusiast

When you’re keeping puffers (or any fish, for that matter), it’s super important to always make sure you are using a quality tap water conditioner, like Seachem Prime, whenever you add new water to your tank. If you don’t, your fish may end up dying from heavy metal poisoning, or because of the Chloramine and Chlorine, present in most tap water.

Before you keep reading, please note that this post does contain my affiliate link, which means I’ll earn a small percent of the sale if you decide to purchase a bottle of Seachem Prime through my link. That being said, the following is my honest opinion of the this tap water conditioner, and I do personally use it on my own tanks.

Average Price: $7.43-$170.70

Sizes of Prime: 50mL, 100mL, 250mL, 500mL, 2L, 4L

Features: Seachem Prime helps remove toxins, like Chlorine, Chloramine and Ammonia, and it also gets rid of the Nitrite and Nitrate.

What’s so great about Seachem Prime?

Multiple bottle sizes:  There are quite a few different options to choose from depending on the size of tank you’re running – from 50mL bottles to 4L containers.

I’ve accumulated so many fish tanks now that we’ve had to set up a separate room of the house in the back to accommodate all of them. Yup, I got bit by the aquarium bug! Because of the sheer volume of water I have to change out every week, I really enjoy finding quality water conditioners that I can buy in bulk. Scratch that. I really enjoyed finding out that I could buy Seachem Prime in bulk – I haven’t used another water conditioner for the past 6 years. It’s just that good.

I really like the small 50mL bottles of Prime because you can measure it out in drops instead of capfuls. Although that may seem like a silly feature to those of you who are great a math, I’m not (seriously, I barely scraped by in Calculus), and I hate having to do conversions. Measuring out 2 drops/gallon is a lot easier for me when I’m trying to treat small tanks. I always keep my 50mL bottle of Prime handy next to all of our 5 gallon and under snail tanks, and I just refill it when I run out.

Removes and detoxifies: As per the bottle, Prime removes Chlorine, Chloramine and Ammonia, and it detoxifies Nitrite and Nitrate. You can also use it in an emergency if your tank suddenly spikes in Nitrite until you can figure out what causes the spike.

What’s not so great about Seachem Prime?

Price: Although it may seem a little bit pricey compared to some of the other brands on the shelf, you’re actually saving money by going with Seachem Prime – take a minute to read the instructions on the other bottle! I almost chose a brand of water conditioner from Top Fin the other day because the bottle was twice as big and I was strapped for cash; however, when I flipped the bottle around to see how many gallons of water it could treat, I noticed that you had to use almost double the amount of the Top Fin conditioner to treat the same amount of water that Prime can treat.

False Security: Although this has nothing to do with the actual product, too many new aquarists read that Seachem Prime can remove the Chlorine, Chloramine and Ammonia, as well as detox the Nitrite and Nitrate – and then they just quit doing water changes. Or, they run out and buy Prime when they have a spike in Ammonia, and then leave it at that.

It just doesn’t work that way! You should never rely on chemical Band-Aids for your puffer tank. Even with a quality tap water conditioner, you still need to conduct large, frequent water changes if you want your fish to thrive. Additionally, if your tank is experiencing an Ammonia or Nitrite spike, then you need to find the root cause of it; not just cover it up.

So, is Seachem Prime a good purchase for your fish tank?

If you’re serious about keeping freshwater puffers as a hobby, I highly recommend purchasing Seachem Prime as your water conditioner. It gets the job done, and it does it well, too. In fact, it’s the only water conditioner that I 100% trust to use on my own fish.

Remember, when you’re directly adding new tap water back into your fish tank after a water change, always add enough Prime to treat your entire tank – not just the new water. So, for example, if I’m changing 50% of the water on a 200 gallon fish tank and I’m using a Python to put the water directly back in from the sink, I would add enough Prime to treat the base amount of 200 gallons before I start adding the water; it would be incorrect to only treat 50% of the water, which would be 100 gallons in this case.
