Now let’s discuss the good and the bad of using plane old tap-water
After the system has been established and the Beneficial Bacterium has a foot-hold in the system, let’s look at what happens when a little amount of chlorine-tap-water is added on a daily basis, first the chlorine is going to assist the BB in fighting off the bad fungi (algae) Here’s how it does that, first we need to understand that chlorine mainly attacks the multi-cell bacteria such as algae, the Beneficial Bacterium that we are harboring and colonizing is a single-cell bacteria that not only lives in the pores of the lava rock but because of their microscopic size can even penetrate the fibrous roots themselves, thereby the chlorine that is introduced into the Bio-System will attack the multi-celled bacteria first and thereby using up what little chlorine is introduced to the system. Now on the other hand if you use something like H2O2 (hydrogen peroxide) in the Bio-System you will be successful in killing all bacteria in the system, hydrogen peroxide will penetrate the lava rocks and the fibrous roots and kill even the roots too!!
I use nothing to jump start my Bio-Buckets, simply fill them up and turn on the fan’s to circulate fresh air in the grow/room, let set for one to two weeks and your ready to go; no need to get complicated with this thing but if you want I suppose there are products out there that would do the trick for you but most importantly remember were not raising fish were growing huge mj plants!! This changes every thing.
