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

I was having a hard time getting my tank to cycle before the fish I ordered arrived in the mail. Because I was running out of time I ordered this product, started it on a Tuesday, put my fish in on a Saturday, and was done by the Monday. I just tested my water and have no ammonia or nitrates and between 5 and 10 ppm nitrates. You need to use the Prime with it every other day during the cycle (1 mL per 10 gallons) to bind any ammonia to make the tank safe for the fish while the tank is getting started. I would not have known this if I had not called Seachem support. Seachem support is AMAZING. So helpful. They explained how the products worked together and answered every single one of my questions, which there were many as this was my first fish. I recommend this product, but more I recommend this brand.

I try to do a water change once a week, and add Stability each time in the recommended amount. It really seems to help keep the chemistry stable.

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.

Ive been using Seachem for years and they have never failed me. Their products are great and the stabilizer definitely does its job well. My fish are alive and healthy!

No more no less it works. Cycled my 75 gal with 1 bottle of Stability & a very small amount of filter media from an established tank. Only took a week and a half, two weeks tops.

As someone that is very serious about the fish keeping hobby, Seachem products are my go to. Seachem makes fantastic products that actually work, are consistent, and readily available in stores for the most part. Make no mistake, Seachem Stability is a 5 star product. Seachem Stability along with Prime really do make it possible to go from new aquarium setup to stocked with fish the same day. No more sitting around for weeks even months while a tank naturally goes through the nitrogen cycle. Ive used this method a few times when setting up new tanks and have not a lost a fish from adding them in a tank to soon yet. Seachem stability can also be used when adding new fish to established aquariums to give the beneficial bacteria in the tank a boost to help with the additional bio-load. I also use it whenever I do tank maintenance, because that is when you are most prone to killing the good bacteria in the tank and filters. The reason why I gave this 3 stars instead of 5 has nothing to do with the product itself. Like I said Seachem stability is a 5 star product. I usually by it in my local fish store but chose to order it from Amazon for the first time along with some other items I was ordering. I received a bottle of Stability that had expired about 3 years ago. I understand mistakes are made and things get overlooked, but how do you overlook something thats been expired for 3 years. To me that is no simple mistake, rather just pure negligence. I will never order anything that expires from amazon again.

It works. Used it to start a brand new fluval edge 12 gal with sand substrate. Water treated with Prime, added a handful of live plants and started the 7 day dosing. On day 2 added a handful of tetras and a couple cories. Add a few more after 7 days. Throughout the 7-day period, and over the 5 months since, I NEVER detected ammonia or nitrites (0ppm) and have seen low nitrates (~10 ppm) using API kits (both test tubes & strips, repeatedly as I had a hard time believing the results). Virtually instant cycling, which I did not think was possible but I now attribute to using this product in conjunction with LIVE PLANTS, which gobble up ammonia and nitrates. Cant stress enough how much better a planted aquarium is for maintaining water quality and healthy fish. Ditch those plastic plants, try a few of the more common aquatic plants until you find ones that do well in your particular setup. Yes its a bit more work --- I follow a regular dosing schedule using Seachem Excel (no CO2 injection) and Seachem Fertilizers (Flourish, Nitrogen, Potassium, Phosphorous) and have beautiful thriving plants and healthy fish (and now shrimp, too)

I have STRUGGLED with new tank syndrome in the past, even after cycling the tank for a month before introducing new fish. I finally decided to take a different approach and order this product. I went with Seachem because I have had great success using their Prime solution to dechlorinate the tank, and Im so glad I did! My water parameters have been on point! The second thing I LOVE about this product is, my water is finally CRYSTAL CLEAR! I know I sound overly excited about this review, but if youre an aquarium enthusiast, you know how frustrating these things can be. Ive tried everything from adding carbon filters, using Water Clear products (to no avail), even adding additional filtration to the tank, and NOTHING seemed to work as well as I wanted it to...until now! Id highly recommend this product.

I have read a lot of the reviews of problems people have had, while I dont agree with the claim of instant bio filter as in my 30+ years I have never seen or found any product that will actually create a full, stable cycle, only time and the miracles of nature, I do not believe any cycle that is rushed is stable enough to handle what is thrown at it! I do think Seachem would be wise to change that! There really is no shortcut to a proper cycled tank that could take up to 6 weeks! This stuff is really for the routine maintenance that it is more suited for like filter maintenance or gravel vacs anywhere or anytime you might loose Benifical Bacteria. I only use this during those times on my 90,135 & 220 gallon tanks and have had zero issues others have claimed which tells me there lack of understanding of the nitrogen cycle or what the product can really do! This product will no way cycle your tank it may help but too many factors contribute to a completed cycle. What this will do is help during routine maintenance to replace loss of BB as well as it could aid in any small spikes. I also will not deduct stars for bottles leaking and or damaged as others have done (guess they dont understand product reviews? If Seachem shipped then different story), as that has zero to do with the results of the product

Id like to mention that I fully anticipated to receive this in mid April, and instead it arrived a month ahead of time and I couldnt be more grateful. My betta fish tank has begun the nitrification cycle with my betta in it, and in order to keep him as safe and comfortable as possible, I needed this product and Im so happy to be able to have it to speed up the process in the safest way possible. I completely trust Seachem with each and every one of their products, and Im so happy to have been able to order it from such a reliable source. Thank you!!
