Fluval Cycle Water Treatment, 2 L

As described

I use this product when setting up a new aquarium (as part of the nitrogen cycle to promote healthy ammonia eating bacteria growth, a 6 to 8 week process) and as part of my weekly water changes. I feel that this product works very well, as my fish are all happy and healthy and I have never experienced any bad water quality issues (ammonia spikes etc). I use this weekly to add to my 200ltr, 60ltr and 30ltr aquariums when I do a water change. I change 20% - 30% of the water volume and add an appropriate dose of this stuff, however it's not really possible to overdose so it does not really matter if you add a little bit extra. I usually do add a bit more than stated on the label. I keep it stored at room temperature and the 2ltr bottle usually lasts me about 6 weeks. There is always a seal covering the opening after the lid has been unscrewed, so you know it is brand new and has not been opened / tampered with. This is safe for my fresh water aquarium inhabitants, of which I have many varieties. Pros: - The larger 2ltr bottle is excellent value compared to the 250ml or 500ml bottles - Quick delivery / repeat orders available - Far cheaper than my local pet store Cons: - Nothing I can think of really I hope this review has been helpful to you. Happy Fish Keeping!

I got a new aquarium so new substrate, new filter, (new everything, basically). I filled the tank and let it run for a few days then added the first dose of the recommended three day initial course of Fluval Cycle. On day two a test strip showed all levels of potential concern (ph, chlorine, carbonate, total hardness, nitrite and nitrate) were within acceptable parameters. Accordingly it looks like I could have introduced fish before I had even introduced the second measure. Instead I waited until after the third dose, introduced some neon tetras and two catfish and they are as happy as any fish I have seen in established tanks. I'm confident further measures of Fluval Cycle weekly, at water changes and when introducing new fish can only be beneficial.

Me ayudó a ciclar el acuario, fue bien, el bote es pequeñito eso sí.

Es el mejor complemento para tu acuario. Provee de elementos biológicos para que el agua y los peces se encuentren en perfecto estado siempre

Très bon produit pour aquarium. Les produits canadiens Fluval sont vraiment à recommander pour que votre aquarium, comme le mien, soit sain pour vos poissons ! je recommande !

Just upgraded my rating to 5 stars, after tentative 4 star rating, now that the product has proven itself! HIGHLY RECOMMENDED . . . tank is crystal, crystal clear after use while adding many new fish over just a couple of days. I immediately ordered it again. This is my new "best buy" for this type of product. **Initial Review** I've used Jungle StartZyme for years, then gave Tetra SafeStartPlus a try. They have worked very well but I was shopping for a better price/larger size for "start-up" bacteria. FluvalHagen is a respected, established name and the product description read better than others I was considering so I bought this. Have only used it once but could see the difference in the tank overnight. I noticed while reading through many of the reviews on these bacterial "quick start" products that many people had negative things to say to the effect that they are useless or don't work . . . They DO Work! The short version is the tank must "cycle" to make an aquarium work properly for the fish to survive and be healthy. No amount of filtration can substitute for the natural cycle of beneficial bacteria that "eat" the fish waste & uneaten food in an aquarium. Bacteria are needed to do that. These "bacteria in a bottle" make that happen much faster, instantly for the most part. I also noticed some users were adding this before they have fish in the tank . . . bacteria and fish work together. There's no point in adding this type of product to an empty tank, the bacteria need the fish waste so they have something to eat! The fish need the bacteria so they don't get sick/die in their own waste before the cycle is balanced. A couple of **hints** for those new to fish keeping: overfeeding is the biggest problem with fish. Do Not feed more than the fish clean up within 5 minutes! It's a lot less than you think. It's fun to feed the fish but every single bit that isn't eaten immediately pollutes the tank and that's what kills the fish. Better a few small feedings than one big one. Do Not put too many fish in your tank, the "rule" is an inch of fish per gallon of water and the bigger the fish the bigger the mess! Don't add all the fish you want at once. Set the tank up, add this product, then add your first few fish. That can be done the first day, you don't have to look at an empty tank but feed very sparingly. That lets you figure out how much to feed while the filter starts to populate with bacteria. If the water stays clear, doesn't smell and the fish are doing good, then you can add a few more fish. Use this "liquid bacteria" per the instructions until you have successfully established the aquarium, then do your regular water changes as there needs to be "new water" in and "old water out, about a 3rd of the volume every month. There's no substitute for regular water changes, light feeding and live bacteria in the tank regardless of the type of fish or aquarium . . . be it a jar with a Betta or a fancy set up full of expensive exotic fish.
