Review: Strong, reliable, and multi-use—solid water treatment for chlorine, ammonia, and nitrite control. - This bottle’s built for serious water prep—removes chlorine, chloramine, detoxifies ammonia and nitrite, and supports biofilter health. Geared toward freshwater and marine tanks, whether you’re doing full water changes or topping up. One capful treats 200L, so the 500ml bottle lasts ages. Works well in van stash, fish rooms, or home aquariums where water quality needs to stay tight. No smell, no clouding, and safe for all species. Ideal for new setups, emergency spikes, or routine maintenance. Can be used alongside meds and other treatments without clashing. Best dosed with a syringe or pipette for accuracy—cap measurements are rough. 👍 Pros ✅ Highly concentrated—small dose, big coverage ✅ Detoxifies ammonia and nitrite—supports cycling ✅ Safe for all fish, inverts, and plants ✅ No smell or residue—clean dosing ✅ Long shelf life—stays potent 👎 Cons ❌ Cap dosing is vague—use a syringe for precision ❌ No colour indicator—can’t see it in water ❌ Not a full-on bacteria booster—use with bio support if needed
Review: Great product. One of the best. - Always use this product with other seachem products. One of the best and cheaper on desertcart than I have seen. Generally I use after a water change. I use with clarity and the water quality is at its best when used. Very effective in keeping water quality and cost effective buying bigger bottles. Works quickly so I know my aquarium and fish are safe.

## Questions & Answers

**Q: What dosage would i need for a 45 litre tank please**
A: I prepare my water in 10 litre buckets, I put 5 drops in each bucket of water before adding to the tank. So for 45 litres of fresh water you would need 23 drops.
The bottle comes with a flip lid and a small hole so it is very easy to dispense one drop at a time.
It doesn’t seem a lot but it works, the best you can buy. I never use anything else. 
Hope this helps.

**Q: I’ve been trying to cycle a new sponge filter 60 litre freshwater tank and nitrites level is high. Can this product help reduce nitrite levels?**
A: Yes it will, but reducing nitrates isn't it's main feature, do small daily or every 2 days water changes, the levels have to spike before they drop,add some fish food even if the tank is empty and also check the tap water levels.

**Q: Very expensive its only£6 80 in my local pet shop have you anything cheaper**
A: Prime is very concentrated. You only need 10ml to treat 400 Litres! most other products require about 10ml to treat 40 L. So it lasts about 10 times as long as them.
If its double the price... that's still 5 times better value.
Prime also detoxifies ammonia and nitrite.

**Q: do you need to use this every 48 hours? or just the once then every week when doing a 20% water change?**
A: If you want to use this specifically to detoxify high levels of nitrite, nitrate etc, then you need to dose every 48 hours. 
If you wish to use it to condition water change water, then you only need to add it to the water that you're putting into the aquarium.

### ⭐⭐⭐⭐⭐ Great product. One of the best.
*by S***H on 6 December 2025*

Always use this product with other seachem products. One of the best and cheaper on amazon than I have seen. Generally I use after a water change. I use with clarity and the water quality is at its best when used. Very effective in keeping water quality and cost effective buying bigger bottles. Works quickly so I know my aquarium and fish are safe.

### ⭐⭐⭐⭐⭐ Genuinely wouldn't keep fish without it!
*by P***X on 16 February 2026*

It doesn't just remove chlorine; it actually 'binds' ammonia and nitrite into a non-toxic form for up to 48 hours. This was a total lifesaver for me during a mini-cycle. It’s a five-star, high-quality product that gives you proper peace of mind every time you do a water change. Plus, it helps the fish produce their own natural slime coat rather than just adding a fake oily one. Brilliant stuff!
