Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums, 16.9 Fl Oz (Pack of 1)

Pros: -Fast-acting. I rely on it often during emergencies, and its potent. For example, I recently used 3 caps on a terribly neglected 3-gallon tank of water with ammonia readings as high as 8ppm (-In other words, ultimately lethal to most any fish that dont have the ability to draw oxygen from the water surface like bettas and gouramis. And even they will eventually chemically burn their gills by breathing it in, anyway), and 8 hours later the ammonia readings came back at 0ppm. Cons: -Make no mistake; ammonia concentrations over .50ppm WILL kill the beneficial bacteria colony youre trying to estabilish from your bottle of Stability. If you really cant do a full water change and need to use this on an already highly polluted setup, use a generous amount of Seachem Prime to temporarily detoxify said ammonia so that the beneficial bacteria have time to eat it before it kills them. -It is not uncommon for a fresh bottle of Stability to arrive carrying pollution of its own. I would suggest immediately using an ammonia test kit (-Do NOT use tests in the form of strips if youre new to aquarium keeping) on the contents of the bottle. If concentrations are higher than 1ppm you will likely only be adding dead microbes to your tank, and as they decay they will make things even worse for your fish. -Although harmless, large quantities of Stability can cloud your water. If you experience this and it really bothers you, take it as a sign that you need to cut back on the size of your doses. -Although it does have a decent life expectancy, do not assume your Stability will last until the purported use-by date. I would not recommend buying large bottles of it unless you know, for certain, that youll be using it within a few months.

After attempting to cycle three new tanks using traditional means with no success, I did lots of online research and discovered everyone in the forums and YouTube videos touting this product. At my wits end, I decided to purchase this product and give it a try. I am pleased to say that after less than one week of dosing my three tanks with this product (according to the written instructions, of course) they are all now fully cycled and producing optimal parameters according to my Tetra EasyStrips. I am so happy I discovered this product, which I cannot recommend enough to those of you who are looking to quickly and safely cycle your tanks for a healthy and happy aquatic environment for your marine or freshwater fish.
