Essential for Freshwater Aquariums â Must-Have for Healthy Fish!
Iâve been using the API Aquarium Salt for my freshwater aquarium for quite some time now, and Iâm thoroughly impressed with the results. Hereâs why Iâm giving this product a full 5-star review:
1. Promotes Fish Health:
This aquarium salt is great for promoting the overall health of my fish. Iâve noticed an improvement in the vitality and color of my fish, especially when used during water changes or to help treat minor illnesses. The salt provides essential electrolytes that help maintain osmotic balance and promote a healthy immune system for the fish.
2. Works as a Healing Aid:
Iâve used this salt to treat minor ailments in my fish, such as stress or injuries. Itâs been especially effective in helping fish recover from small cuts or scrapes. I follow the instructions, and it seems to work wonders in speeding up recovery and reducing stress levels in my tank. Itâs also helpful when acclimating new fish to the tank environment.
3. Perfect for Freshwater Aquariums:
Iâve used other salt products in the past, but this one stands out for its quality and effectiveness specifically for freshwater aquariums. It dissolves easily and doesnât cloud the water, which is a huge plus. The water quality remains stable, and the salt doesnât cause any harm to my plants, which is important since I have a planted tank.
4. Safe and Easy to Use:
This product is easy to measure and dose according to the size of my aquarium. I appreciate the clear instructions on the box, which helps me ensure Iâm using the right amount. I also like that it doesnât affect the pH of the water in a harmful way. Iâve had no issues with the salt causing unwanted spikes in my tank’s water parameters.
5. Great Value for the Price:
The 67-ounce box is a great value for the price. It lasts a long time, as you only need to use a small amount for each water change or treatment. Given the quality of the product and how much it improves the health of my fish, this is definitely worth the investment.
6. Packaging May Vary, But the Quality Remains the Same:
Although the packaging may vary from time to time, the quality of the salt remains consistent. Iâve used this product several times, and every time, itâs been effective and high quality.
Final Thoughts:
The API Aquarium Salt is a must-have for any freshwater aquarium enthusiast. Whether youâre looking to improve the health of your fish, treat minor injuries, or simply maintain a stable environment, this salt does it all. I highly recommend it to anyone with a freshwater aquarium!
ð¯ Highly recommended â a great addition to your aquarium care routine for healthy fish!

As advertised, aquarium salt (a good chunk of it too)
Exactly what I needed, some aquarium salt for curing the odd ick infection. I wasnât sure how large the container would be and I sure wasnât disappointed when I got this, bigger than I was expecting and absolutely perfect! My order arrived quickly, nothing was damaged, and everythingâs exactly as advertised and works as it should.
I already treated my fish with this box of salt and it took the ick out quickly, so I can verify it is certainly the right kind of salt to use for healing fish. Iâll be buying here for things like aquarium salt and replacement filter cartridges, it was nice to find both in the same place, thanks for an easy and wonderful transaction!

It works for the fish! Bad for live plants!
I’ve used it in distilled water for my betta. The before and after photos are taken about 8-9 days apart. It works!
I initially did a 25% partial water exchange with the new water+salt, and 2 days later did a 50 % and a few days later did an almost full tank water exchange. Fish acclimated well and is healing.
But it’s killing my live plants. I’m sure I will have to replace the plants given the rate they’re dying, but they’re not expensive ones so I don’t mind.

Used to help Betta fin rot, minor complaints (Betta fin rot information included if you need help!)
I purchased this API aquarium salt for it’s healing properties in my freshwater Betta tank. He was coming down with a tiny section of fin rot because of poor water quality for a short period of time. This, along with very frequent 25%-50% water changes helped heal his fin rot. (The water changes alone may have worked fine, but I wanted to add salt for extra help in regrowth.)
I really only have 2 complaints:
1- The granules vary, but some are quite large. Even by adding them to a small cup of boiling water and stirring frequently it took several minutes to properly dissolve. If not dissolved properly and added gradually it can burn your fish!
2- The directions are not very clear. They are listed in 3 languages, so that’s nice, but there is plenty of room for more clarity on dosing your tank. (The product label is on 2 of the 4 sides so they could actually use another side for information to add clarity.) It states that you can either add 1 rounded tablespoon for every 5 gallons OR 1/2 rounded teaspoon for every gallon. The fist measurement gives you a 1 tbsp to 5 gallon ratio while the second measurement give you a 0.83 tbsp to 5 gallon ratio. I guess it’s trying to be helpful for those with a tiny bowl or small hospital tank??? It mentions NOTHING about dissolving the salt first or adding it gradually. If you are treating your fish and don’t happen to learn that in your own research, then you may end up just plopping the measurement into your tank and harming your fish.
***I do appreciate that it mentions that some live plants may not tolerate the salt. I chose to risk it and many did ok. They didn’t grow much, but didn’t seem harmed. A few did lose leaves and kinda melt away though. I simply removed those that were not tolerating the salt for the time being.
***I also appreciated the packaging mentioning that the salt does not evaporate so be careful not to compound it. For example, when I did a 25% water change, I dissolved and added 25% of the salt I had previously dosed my tank with to the new dechlorinated water.
Compared to other retailers the price is good considering the volume you get. Plus the convenience of not going to a store is nice.
NOTE ON TREATING BETTA FIN ROT:
(Just thought I’d add this in hope that it might be helpful for someone.)
Fin rot is common, so don’t feel horrible if you are dealing with it. Doing lots of research before any treatment is very important! Anyone can type anything on the internet that information will pop up in a google search. Read lots of different opinions, watch many reputable/informative videos and do your best to understand why your Betta has fin rot in the first place.
If you don’t have a heater or filter this is the first change your should make when combatting fin rot. All Bettas (even healthy ones) with benefit from these tank additions. (If your house temperature NEVER falls below 78F you may not need need a heater, but most of us do for at least part of the year. It can easily be unplugged or removed when not needed.) Bettas don’t like a strong current so a sponge filter works great. If you have a filter that is built into your aquarium or came with a set, there probably an easy way to baffle it for your Betta’s comfort. I added an aquarium sponge to the output of mine.
Your could be biting it’s own fin which looks like bites taken out opposed to a fraying or melting of the fins. This often happens on the caudal (think tail) fins pretty much in line with where your Betta’s mouth could reach. You may even observe your Betta seemingly “chase its tail.” My research tells me this often happens when a Betta is unhappy so consider if your tank is large enough. Betta’s enjoy stimulation so a Betta leaf, hide and silk plants are an easy addition to try if you don’t already have them.
The fin damage could be caused by sharp objects in the tank. This may look like a tattered or ripped fin. Betta fins are very delicate. It’s good to check all decorations thoroughly by rubbing your fingers over them. You can possibly alter them to make them safe (like sanding down a rough area of driftwood) but be sure that only soft items are in your tank. Even some plastic plants may be damaging your Betta’s fins so many people recommend silk or live plants only.
Unclean water may have caused your fin rot. Even if it looks clear to you, it may be full of harmful ammonia, nitrites or nitrates. If you don’t have a test kit, investing in one will help keep your Betta healthy. The API master test kit provides LOTS of tests and is very accurate.
For me, I learned that I was not cleaning my tank the best that I could. I house 1 male Betta and 2 Nerite snails in a 5 gallon planted tank. Nerite snails help with algae, but they also poop a lot, so there was lots of animal waste my tank. Because I have a planted tank and was trying to allow some plants to carpet the bottom, I did not agitate my substrate enough when cleaning. I was also not consistent with my weekly water changes when work got busy. Big mistakes that led to a little fin rot.
Along with 25% weekly water changes to reduce waste it is important to gravel vac the detritus up from your tank so that bad bacteria does not grow in your substrate. Use your siphon to press down into the substrate. Once you see lots of substrate getting pulled up (along with the detritus) lift the siphon a few inches out of the substate and give it a wiggle. This should release the substrate but allow the detritus to continue up the tubing. (If substate gets caught and slows down suction it can easily be removed by taking out your siphon and piking it with a clean wooded skewer.) If you are working around plants, do this method to the exposed substrate only. Wiggle the vac or use a clean/unused wooden chopstick or skewer to agitate around the substate of your plant. This will make the detritus start to float into the water and you can suck it up there.
I also find it helpful to take a new toothbrush that I have designated for tank cleaning to the leaves of my plants. I noticed some brown algae (diatom) buildup forming on them. I initially thought they may be dying, but the brown layer came off easily and once removed it helped them grow better. On smaller leaves I just gently rubbed it off with my fingers. I use the same brush to scrub off my driftwood. You can use it on the inside glass of your aquarium too if you have a large buildup of algae, but if not then you don’t need to.
I have moss glued to my driftwood so I use my hands to agitate that and sometimes pull or trim off excess or weakened growth. This helps encourage new growth. I plop any removed moss into an open mason jar full of dechlorinated water and set it on the window sill to grow more fresh green algae over a month or so. Sometimes I replace that water and sometimes I top it off with a splash of old aquarium water for some plant nutrients.
It is also important to note that if you have any uneaten food (pellets that fall or messy bits from a frozen food feeding) you should pull out your siphon and remove them within a few minutes. They will pollute your tank and cause problems for your fish (and you).
Sometimes you have to learn the hard way, but cleaning your tank is often more involved than just scooping out some water once in a while! Good luck with your fin rot and don’t forget to do your research!

It Didnât hurt My Freshwater Fish
Salt is salt, well kinda. I wanted to play it safe and get this aquarium salt to make my fish happier. And honesty, I was trying to help out with a sick fish, but it ultimately did not work. Still, adding a little salt to a freshwater tank is very helpful in the long run. Most big box stores do this to their aquariums. Recommend.

Being a new hobbyist wanted to be on the safer side so went for a renowned brand and was not disappointed by the quality at all. Although a little on the pricier side but is total value for money if you value life. Thanks Amazon for providing an entire array of products.
