Why do you need to clean with strong disinfectants?
My betta built his nest but in the pet shop they told me to clean the water the drops tough killed the nest After 2 weeks and still nothing Is he going to rebuild it or does he need a less clean water?
Disinfectants can be classified in two different ways. One is by what type of chemical they are. For example, the active ingredient in Lysol is O-phenylphenol. Phenol and some other disinfecting chemicals are chemically similar. Another way to classify disinfectants is by how many hard-to-kill microbes they are effective against. High level disinfectants can kill most endospore-forming bacteria which tend to be very resistant. There are intermediate level and low level disinfectants as well.
