Not sure this is ok
Update: fish didn’t die lol! Emailed the company and they confirmed this is how is supposed to be. Not sure if it works but I’m using it when needed.Original review: Unsure if this one is a bad one, but I opened the lid. Had no seal. Not sure if it’s supposed to. I poured the dose in and it was so thick it looked chunky in the water. My angel went and ate a bunch of it. The only bit that wasn’t eaten landed on the bottom of the tank and isn’t dissolving. I’m worried now this is not good and I might be losing fish. I did email tetra worried about this now and hoping for clarity. I know ordering from Amazon sometimes we don’t get the authentic product which now I’m really regretting not running down to the store and grabbing a bottle.

Really Improves Water Quality
I’ve had a lot of problems with elevated nitrates for quite some time despite frequent water changes. I managed to stumble across this product after doing a Google search on ways to decrease nitrates and thought I would give it a try.I did notice there were several comments regarding this product making the aquarium water cloudy but did see a comment that mentioned giving the bottle a good shake and whisking before adding the water to the aquarium. I’ve done that and haven’t had an issues with cloudy water and my fish appear to have a lot more pep over the course of the last month. As well, test strips are showing a steady drop off of nitrates in the water. Don’t expect that to happen overnight. And you have to be consistent with your water changes using a gravel vac.I have a 20 gallon tank and usually replace 20% – 25% of the water weekly. I give the bottle a good shake and add 2 cap fulls of EasyBalance to approximately 1 gallon of water. Give it a really good whisk and add the rest of the water. I tried whisking with a full 5 gallons of water in the bucket and did have some slight cloudiness in the aquarium water. You won’t get as good of a mix if you whisk in a full bucket of water versus a small amount.I recommend this product to help improve the health of your aquarium.

Good price
Better price than local store.
Small Bear –
It is 100 times cheaper than another product sold at PetSmart. The other one is a diluted version for small tanks; this large bottle is condensed and works just the same.

Quite Good.
L&O –
Mantiene los niveles óptimos. Recomiendo agitar la botella al menos un minuto antes de usar.Jamás he tenido problemas con los grumos, pero se logra una mayor combinación con el agua haciendo esto.
