A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.

All you would be doing is storing poisons in the tank for release later if there is a power out. This would result in death to the whole population in the tank. Most experienced aquarists believe that poisons should be collected and treated outside the tank in a properly cycled filter where the Ammonia is converted biologically into harmless Nitrate.
I strongly recommend the Whisper filter. It is so easy to use -- you literally just take it out of the box and hang it over the side of the tank. No assembly required. Replacement filter cartridges (called Bio Bags) are sold separately.
