I have a fish tank and I would like to use the water on my pot plants. I do use a de chlorination product when I add water to the tank.
Is this product safe for pot plants? Will it harm them?

If the active ingredient is concentrated vitamin C you are OK for plants.

Take a look to the ingredients of that product, if it is not based in vitamin C and has sodium instead it will harm your plants … 
Typically, dechlorination is accomplished by adding sulfur dioxide or sulfite salts (i.e., sodium sulfite, sodium bisulfite, or sodium metabisulfite).

I know one of the chemicals sodium thiosulphate used to be used medicinally IV to fix metal poisonings. I use it in photography also and its regarded as generally harmless idk if you would smoke it though
I just filled a five gallon pail and let it sit when I lived in a place with city water and had saltwater fish. I read it in a Fish Book and it didn’t kill them and saltwater are delicate. Just my experience I. Maybe than didn’t make the good stuff than.

Interesting. So we’re talking “non-harmful” for smokable product or for the bacterial health in the soil?

Hey George my tap water always has alot white sulfur in it naturally. Am i good to just let the chlorine evapporate? I normally use fresh spring water I bottle myself. But winter is comming and I’ll need the tap water.

In the ancient ages when someone was banned they threw salt in their fields so they couldn’t have more crops. Sodium (in excess) is toxic, it can significantly slow growth and you may accumulate salts buildups. Sulfur is OK and one of the essential nutrients, but any excess may lower your pH and make your soil acidic so your plant would miss nutrients.
I would use that water and check the plant reaction, it’s easy to detect an excess …

PH is 7.8 out of the tap. No worries.

Looks like the spring water needs to be stored up and maybe mixed with the tap water to avoid the burn.
It freezes in winter? 
Thought you were still in the attic and spring water was mineral water until I noticed the pic 
. Mixing both could be a good solution …

A decent two stage water filter will remove chlorine and chloramines. Don’t even need it to be RO
First of all, I would highly suggest you dilute fish tank water before feeding it to your plants. Use about a 1/4 cup per gallon.
Second off, I wouldn’t worry about the de-chlorination products and your plants. If it is safe for fish, it should be good for plants.

Why dilute fish tank water?

It’s really high in nitrates. IME it can burn your plants. My dad burned the crap out of his plants watering with full strength pond water one cycle.
