You can use bleech if you know what you are doing. I bleech my tanks every 12 months (without the fish in them obviously!)
All you do is add a few drops of bleech to a large volume of water and leave it to soak for a few hours. Then Rinse the breeding trap with copious amounts of water, before adding it to a bath of aqua safe and water. I normally add twice the reccommended dosage of aquasafe and i leave it for an hour to soak OUTSIDE! Apparently the suns UV rays can also remove the chlorine in the bleech as well as the aquasafe. Then remove it from the bath and let the sun dry it. Now its ready to use.
Many people on this site use bleech, esecially when cleaning out ceramic co2 diffusers. But remember, use your common sence, bleech can kill fish so dont ever put it in your tank unless advised to.
Also, theres no need to clean out the breeding trap. Just rinse it under running water will do fine.
