Hypochlorous acid

for what its worth, i bought a hypochlorous acid generator once, it uses cooking salt, water and electricity.
the generator itself do work, you get some swimming pool smell and i would say it cleans quite well.
the hypochlorous acid made by these cheapos isnt as stable, long lasting as the bottled stuff you can buy (bit ago ive read about it, it depends on the generator).
but thats no concern as its so cheap to make a new batch.
havent used it in hydro, just for cleaning, so ymmv.
Cool. I didn't know you could get a generator. Will look that up!

Hypochlorous acid is a scam as marketed to the hydro industry

It can't be isolated and only exists when chlorine dissolves in water.

I.e. Anyone using pool shock or chlorine bleach is creating HCLO
Ok. Well this is why I opened this thread! I don't know much bout it so hearing from someone who does is what I was looking for. Love to hear some opinions and I will look this up a well. Thanks for the insight!

This may sound strange, but if you run a protien skimmer, which is normally used for saltwater tropical fish, it will get rid of that biofilm.
yeah i read something like that somewhere but its just too much for a bubble cloner. i just do perlite in trays now and it works so i gave up on bubbles. but yeah good tip

just bought a cheap 10-20 dollar one.
it was so cheap the usb port broke after a few uses.
was just a toy for me, so i am fine with it.
smelled clearly like simming pool and a chlorine test stripe showed also results.
if these units generate really hypochlorous acid or "just" chlorine, i cant tell.
but i remember dark i made some test on some clones, wasnt harmfull, my thunb would say its milder then chlorine.

I got a bottle of it for free from Athena, so used it my current run. Seems to be working good.
Meh won some cash at the casino. That stuff burns holes in my pockets, gotta get rid of it FAST!! lol. Trying it out. See what happens right?!

To make a product similar to UC Roots, Clear Rez etc.
  1. One gallon of distilled/RO water in a clean resealable container.
  2. Add 1 ounce of 5 or 6% Bleach to the gallon of water.
  3. Apply this solution @ 1 ml/gal
I changed the formula a bit so that its not required to add 6ml/gal per Clear Rez directions.

Clear Rez is 0.028% Hypochlorous Acid

Notes
The above formula should get you more around 0.168% Hypochlorous Acid which is 6x the strength resulting in 1 ml/gal instead of 6 ml/gal application rate.
Make sure you only use Bleach containing Sodium Hypochlorite in the ingredients, do not use "splash free" bleach or bleach containing any other ingredients.

p.s you can always use less, preferably use less and see if biofilms etc fuck off. I was having a weird slime in my reservoirs if they sat for more than a couple days and never was able to pinpoint what the hell was causing it. I haven't had any slime (biofilm) since applying this solution to my reservoir.

The problem would be the contamination still existing in the water and passing to the rootzone of the plants, those skimmers don't decontaminate water. If the biofilm isn't the friendly kind that would be unacceptable. Also then you need to run a skimmer pump and why do that when you can just use a few drops of bleach? :D

very helpfull receipe, but if Clear Rez is Hypochlorous Acid it should be HOCl not NaOCL (Sodium Hypochlorite).

Sodium Hypochlorite breaks down into sodium and... hypochloric acid (in water)

Just add water

HOCL is created when Cl dissolves in water, it does not exist in isolation

Cl2 + H2O ⇌ HClO + HCl

makes sense.

always wondered a bit why the process of making bleach is the same as these cheap HOCL generators works.

"The raw materials for making household bleach are chlorine, caustic soda, and water. The chlorine and caustic soda are produced by putting direct current electricity through a sodium chloride salt solution in a process called electrolysis. Sodium chloride, common table salt, comes from either mines or underground wells. The salt is dissolved in hot water to form a salt solution, which is then treated for impurities before it is reacted in the electrolytic cell. "

Maybe you know and want to answer.
Is this single cell membrane electrolysis procedere legit, or just marketing?
"Single Cell Technology
Single cell electrolysis generates only one solution, an anolyte of hypochlorous acid. The electrolysis cells have a single compartment that contains both the anode and cathode and are engineered to generate a single solution with an ORP > 800. Using an acidified brine, a neutral to acidic free chlorine solution is generated that is dominated by hypochlorous acid. The HOCl solution remains stable and the HOCl molecules are only deactivated when exposed to an organic surface or the oxygen in the air. "
to my understanding thats what they sell as bottled HOCl? (longer shelf life).

i havent digged too deep in to it, not using much bleach products atm.

Not a clue

A few decades ago I worked at a lab which had a HOCl generator used for disinfecting equipment. My understanding was that it was made on demand before use and wasn't effective for very long. Science marches on so it wouldn't be surprising if they've developed a way to make it more stable.

I still think the bottled products sold as HOCl are simply over-priced, grossly-diluted bleach solutions until proven otherwise.
