Nutrafin Cycle

[Nick Bramley]

Does anyone else use this product in there aquarium and whats your opinion on it?

A true example of snake oil that at best contains some dead bacteria that will be of little use in the aquarium.

The only products like this shown to have an effect are bactinets and bio-spira which need to be refrigerated to stop the bacteria using up the supply of food in the bottle.
