Frequently Asked Questions
How do I know if my fish has nitrate poisoning?
Nitrate poisoning is a massive concern for anyone who has a fish tank. So it’s crucial to know the potential signs a fish may exhibit when suffering from it. Here’s a quick list to help you identify a nitrate spike in aquarium tanks and address it as quickly as possible:
- Appetite loss
- Rapid gill movement
- Noticeable color change
- Higher respiration rates
- Loss of equilibrium
- Gasping for air at the surface
Any combination of these symptoms is a severe cause of concern for fish owners. If you notice them, contact a vet and try to decrease your tank’s nitrate concentration. A good guideline would be maintaining your fish tank nitrate levels below ten ppm.
What is a good nitrate level for freshwater fish?
A good freshwater or reef tank nitrate level is less than ten ppm. In this condition, your fish will be healthy and comfortable without care or worry. I should also mention that most fish will do fine with water up to 20 ppm.
So it’s not a massive deal if you can’t control nitrate levels to less than ten ppm. Your fish will be fine within the ten ppm to 20 ppm range. When the levels go higher than this, you need to start thinking of nitrate reduction aquarium treatments.
Aside from the removers mentioned on our list, one more practical option would be Fluval Clearmax Chemical Filter Media. It does a solid job resetting an aquarium’s nitrate levels and solving nitrite and phosphate issues.
What is the fastest way to lower nitrates in freshwater aquariums?
Aquarium owners have several methods at their disposal to lower nitrates. Some use a conditioner or chemical to reduce nitrates in aquarium tanks. Others rely on a known nitrate remover plant for freshwater aquarium enclosures like Pothos plants.
I’ve even seen a few people utilize a complicated nitrate reactor freshwater device.
But the fastest way is with regular water changes. Of course, this process requires a lot more effort than utilizing a high-quality remover.
If you decide to use water changes, I’d recommend starting by reducing the tank’s water level to 20%. You then refill back up to 40% and reduce it again to 20%, which takes out a significant number of nitrates. Finally, repeat the reduction and refill the tank to 100%.
You’ll end up with 5% of the nitrates inside your tank compared to when you started. It’s quite a simple and effective way of significantly decreasing an aquarium’s nitrate levels.
How long does it take for nitrates to disappear?
Clearing out a tank of nitrates will take anywhere between two and six weeks. Of course, this process will depend on the aquarium’s size and other factors. But most hobbyists should expect some between this time frame to have their tank completely devoid of nitrates.
So it becomes essential to keep testing during this time with a nitrate detector. My preferred option would be Salifert Master Reef Testing Kit. It’ll have no problem updating you on the nitrate, alkalinity, magnesium, calcium, phosphate, and pH levels.
What is better for nitrate removal, API Nitra Zorb or Seachem Purigen?
One of the common debates among people using nitrate removers is Nitra Zorb vs Purigen. After all, both represent top options within this marketplace. So it makes sense why people compare the two.
In any case, I’ve found Seachem Purigen to be more effective for my particular needs. It’s much more convenient with its recharging ability and longevity. Plus, its performance at removing waste and nitrates is second to none.
But again, my preference doesn’t mean API Nitra Zorb is a lousy product. It wouldn’t have made my list if I wasn’t confident in its abilities as a nitrate remover. It suits most HOB filters and can remove ammonia as well.
