H2O2 to dechlorinate water when planning to use Recharge?

  • H2O2 to dechlorinate water when planning to use Recharge?

    Posted by tjm77 on October 6, 2024 at 5:23 pm

    I’m planning a coco-grow dots-recharge setup for an upcoming run. First time for any of those ingredients, so I’m wondering….will using H2O2 to dechlorinate my tap water kill the microbes from the recharge? (Out of the tap, my water has around 64 ppm @ 7.5ish pH).

    Just use a stone bubbler in a few 4 or 5 gallon water jugs and let it bubble for 24-48 hours…. NO MORE CHLORINE. (Tip: Chlorine is a gas and will evaporate out of H2O faster in warm water.) just my .02

    I hate to be that guy but I have to ask because I just can’t get my head around it:

    Can you actually dechlorinate water with H2O2? Wouldn’t you just get (ideally) ClO2 which outgases on its own but slower than Cl2 or (worst) chlorates and chlorides?

    anyway I can’t see why anyone would bother with H2O2 (or anything else) to get rid of Cl2 when you can let it sit for a day or two and get the same result. It’s not like putting H2O2 in and the chlorine is gone within an hour it takes time too.

    and if you havn’t already check that you actually have Cl2 in your water (might want to know the concentration as well). Where I live they use ClO2 and I just don’t bother with anything chlorine

      That’s all I do it throw a bubbler in my H2O tubs and let it simply gas off …. 🤷

    H2O2 in high doses (4:1 water/peroxide) will kill microbes. 3% H2O2 at 1-2 tsp per gallon can boost oxygen levels of water without killing microbes. H2O2 will have no affect on chlorine. Chlorine will evap even without agitation and levels are not high enough to harm microbe populations anyway. Chloramines put in some city water can only be filtered out. Get a carbon filter if you’re concerned about chloramines. Mix Recharge in water without peroxide and water in from the top. You can put a little peroxide in a reservoir without issue to microbes in the media. Your water is a bit alkaline so I’d lower the pH to around 6 of your water source.

    Unless you’re sourcing your water from a pool, you’ll never have to worry about chlorine . Just altering, the pH of the water will cause the chlorine to convert to undetectable levels.

    Municipal water levels of chlorine are minuscule compared to pool or spa levels. in many cases, you can knock the chlorine out of suspension just by putting your hand in the water.

    Well, 64ppm out of the tap is actually crazy clean and low in practically everything. It’s going to take very little pH down to get you to 6.5 ot whatever you run at, like just a few drops per gallon. Consider yourself very lucky and don’t worry about anytime water wise!

    H2O2 will kill microbes. Just let your water set out for a day or two and the chlorine will desipate.

    Yes for sure chlorine will kill microbes but the low amounts in city water is so low the microbes come back at such a fast rate you wont even put a dent in the.and if your using recharge every week you will be just fine running tap water. If you wanna get rud of chroline anyways It is better to put in 5 gallon bucket and let sit outside for 72 hours and the chlorine will disapate.

    Glad you brought this up! Not needed at all. I’d go out of business if everyone needed dechloranated water to use Recharge 🙂 There’s just enough chlorine/ chloramine in tap water to keep scum from building up inside the pipes. It’s not enough to kill the microbes in Recharge. Tap water doesn’t kill the microbes growing on my sponge in the kitchen sink, it won’t kill the billions of bacteria and fungi in Recharge. Give it a try with the tap water and you should notice a difference in a day or 2.
