I highly recommend this product, fish keeper for many years, I stope as I had to work abroad, put it in you're de chlorinated water as per the instructions and add you're fishes. I am very happy with this product, I can't stress how effective it is, 10 days on and my fishes are all doing well, try and oxygenate you're water with an air stone, not much info on the net cause it's that simple to use! 1 250ml bottle goes a real long way, feed ur fish every other day and do a 25% water change after 3 days and follow up every week with the same amount every 6 to 7 days, don't over stock ur aquarium, 70% of what you have calculated to be ur maximum fish tank volume allowence. I was doubtfully at first cause of all the u tube videos saying that bio starters are all rubish, but people times have changed, the products out these days for aquarium keepers are just amazing! Hagen/fluval are a reputable buisness, I use many of there items like filters and water conditioners for many years, because they don't fail you when you got fish stock, living fish. Defonitly try it as it worked for me awsomely, I feel like I cheated, made my life easy, setting up ur aquarium and cycling it so quickly without seeded media of some sort. Very pleased indeed. Good luck and I hope u all have a great expirience just like me. God bless and happy fish keeping.Read full review

I’ve used this product from the start of setting up my aquarium in 2008, adding some at each part water change. Testing the chemical composition of the water demonstrates the effectiveness of this Product - I never find more than a trace of ammonia or nitrite and the regular water changes keep nitrate levels well under control.
