Quick question, I use tap water for my hydro system. Will Placing the bucket of water under a light help with the chlorine dissipate ?
Not that I know of. Chlorine will evaporate though, and if you bubble it with an air stone it happens pretty quickly.
I have a air stone in my reserve tank linked to my main tank. Both have air stones I can just mix it all up and toss in there hey. No need to wait it out.
I don’t know if that many ppl put a lot of worry into the chlorine count of the tap water. I mean you can test it’s ppm with a tds pen or rather the tap water in general. I mean if that’s what your worry is? I don’t worry about mine before mixing nutes but I’m not hydro!! If that helps at all!! We can ask other ppl if your new to hydro and that’s what your asking?
not an issue – pH is far more important - my local water — the city and my pH meter has 8.6 - insanely high to me — so every water drop i put some lime juice – to get about 6 — and let it go to room temp to avoid temp shock - that ,0000xyz flouride dissipates soon
I’ve read that high chlorine will throw off PH if not evaporated before hand. I use PH perfect from advanced nutrients
I think they mean you can’t use pool water but levels in drinking water arent enough to f up a grow single handed!! Does that make sense or helpful?
A LOT of growers using municipal tap water absolutely do worry about chlorine in their water, regardless of medium.
@Sutton, bubbling it or letting it sit for a few days is your best bet. Or go with distilled or reverse osmosis water. Aquarium dechlorinating drops work ok, too, but I don’t know how they’ll affect pH.
There’s your answer from a hydro guy like DB said, airstones but days not immediately…I’ve heard the osmosis thing before… doesn’t look like lights do the trick though like you originally asked. BAM
Thanks for quick reply everyone. Many thanks
lime or lemon juice is acidic — got that up down stuff - just never bothered with it
hmmm - now says 8.75 — i asked - older pipes so they raise it to reduce damage https://www.siouxfalls.org/public-works/water-division/water-quality
The sun will get rid of the chlorine in your tap water.
You mentioned ph change as chlorine evaporates. This may be the answer to my issue. I Ph’d a gallon of water for a small pot. 6.5 dead on. After I watered I had a lot of water left.
I let it sit out till the next watering and the ph was WAY off.
Just my observation.
Oh pH will definitely change when left to sit out in a bucket!!
pH drift is one of the issues with using things like lemon juice. Not very stable and only makes sense, to me anyway, if you are in a pinch and needed something before you can get a new bottle of pH down.
Otherwise you might find yourself chasing the pH which is a problem in itself.
A couple of things: a municipal water report is a good idea as chlorine dissipates. Chloramines do NOT. You may have to provide chemical intervention to remove it. And I would absolutely worry about excess chlorine.
PH down is buffered to maintain stability and unlike lemon juice, lime juice or citric acid; it’s a micronutrient (phosphoric acid).
I tried this but kept running into iron deficiencies after every watering. Maybe it depends on which brand you get but when I read the fine print it said that it also removes heavy metals. I just went to bubbling instead.
I prefer not adding anything, myself. Luckily, my well water doesn’t have chlorine.
Bubbling or sitting for at least a day is my top recommendation, but some people want instant gratification.
I will also add for anyone that didn’t all ready know , water temperature will also change your ph , the more stable that you can keep your water temps will also help keep your ph more stable…
If you check your ph when your water is cold and let it warm up to room temperature , it will change your ph… if it gets really hot , it will change significantly…
