I'm sorry this is a long post but I want to give you guys the most information I can. After reading this and if you are interested in it please send me a message. Thank you very much, Brandon Each Bag Contains 30 Gel Balls. 1 Bag $4.00 2 Bags $7.00 3 Bags $10.50 4 $14.00 5 $17.50 Or Buy 10 bags for $25.00 Shipping is $2.50 Here is a little story about me and how I found this product. I have used almost every brand of bottled Beneficial Bacteria. I used Stability, TSS, TSS Plus, Dr. Tims One and Only, Fritz 7, and Fluval Bio Blocs Concentrate. The one thing that all these things have in common is that they are all liquid. And once you place it in your tank all the bacteria is dispersed into your water. And that's it, hopefully your tank has enough food to feed the bacteria. Don't get me wrong I have use these products with success but it does get expensive after awhile. I don't know how much bacteria is in one of those bottles but the ones I use has over 8,000,000,000 per liter, yes you read that right over 8 BILLION live bacteria per liter. Plus since this is in a Gel ball it slowly releases the bacteria when needed. It also can dissolve faster if placed in fast moving water. Also if you ever ordered Biohome Filter Media from a U.S. Distributor you would get this same balls from them with each order. I live in Honolulu, Hawaii and I have been selling these to people here and I have repeat customers and everyone that has used them has had great success with it. This product is originally from the U.K. Beneficial Bacteria Gel Balls is an Award Winning bacterial product that helps to maintain crystal clear and healthy water. Gel balls are biodegradable balls, crammed full of live bacteria and enzymes that when added to your filter it works on breaking down Ammonia and Nitrite, whilst cleaning up organic waste. The bacteria and enzymes are slowly released when they are needed most to address biological issues in the aquarium that are often the cause of poor clarity.
