View Full Version : Should I use a bacteria booster after my tank is cycled?

03-14-2009, 08:03 PM
My tank has remained cycled since early this week. Ammonia 0, nitrite 0, nitrate 5.

The packet of Bio-Support I have recommends that I add 1 standard dose to a cycled tank every week.

Why? Is this just so they can sell more bacteria booster?:hmm3grin2orange:

I can't see what benefit it would have in a cycled tank, provided the bio-load doesn't change dramatically. Won't the bacteria just grow/die off as required, provided changes are slow?

I could see adding it when you change something enough to cause a mini-cycle: adding a lot more fish, adding a plant, major disruption of the filter or gravel, etc. But adding it to a cycled tank when no changes have been made?

They recommend it just so they can sell more. It really has no purpose once the tank is cycled. You are right that it may be beneficial in preventing a mini-cylce but even then you can get away with just waiting for your filter to catch up. Its all about the $$.
