Are you kidding?NEVER USE BLEACH, unless your goal is to kill everything. Good for cleaning and sterilizing, that's about it.
Do any of you use tap water?
Drink Tap water?
Chlorine is used to kill pathogens. Things that can do humans harm and possibly cannabis.
If you water with "city water" you are watering with chlorine. Which is what is in bleach.
I did say one needs to use the right amount to get a proper treatment per gallon or liter.
So the idea that this is "Bad" is foolish.
With "Lake" water who knows what things are in that water and what they might do to plants and or plant roots for example.
Adding bleach and letting that sit before use is wise. The chlorine will evaporate and that will leave safe water in my opinion.
I would error on the side of caution.
Also I was wondering what kind of lake this is. Not a good idea if there are farmland runoff draining into it.
ALSO: Edit:
So let it gas off and you are good. Pathogens killed - water safe.Chlorine
You may not realise it but chlorine is classed as a plant micronutrient meaning that it is essential for the proper growth of plants. It is important to note though, that it is the ion (Cl‑) rather than the gas (Cl2) that is used by plants. In particular, chlorine is important for plant photosynthesis as it is involved in the opening and closing of stomata (pores in leaves that enable plants to take in and release carbon dioxide, oxygen and other gases as required. It also helps ensure leaves are firm.
