Hey everyone! I'm dealing with some serious water quality issues here. The tap water in my area is loaded with chlorine (but not chloramine), which is generally considered safe for people, yet I have a sinking feeling it's contributing to the gradual decline of my vegetable plants over a few weeks. I've ruled out overwatering and fungal diseases, so this is really my last thought. I've come across some info suggesting people use fish tank water with these dechlorinator drops successfully. What do you all think? Would these drops actually benefit my plants? Thanks in advance!

You might not need those drops! If you let your tap water sit out for a day or two, the chlorine will often evaporate. Some people fill a bucket and just leave it out, which can do the trick!
Honestly, I think it’s pretty rare for the chlorine to be the issue. I've been using tap water and haven't noticed any problems with my plants at all.
Chlorine might affect beneficial microorganisms in the soil, but it shouldn't kill your plants outright. Also, if you're using really cold water, that could be an issue too since cold soil has trouble releasing nitrogen. I usually fill a garbage can, let the chlorine dissipate, and water my plants with tepid water instead!

Yeah, especially if it's sodium hypochlorite, it breaks down pretty quickly when exposed to air. Just a few hours to overnight should do it. Or consider getting a simple water filter, like a Brita!
