As I mentioned a few posts back, my nutrients only have 1% Ammoniacal Nitrogen, and I use sulfuric acid for PH down, with the occasional phosphoric acid during flowering. (People with jrpeters hydro nutes generally just use the same formula for veg/bloom and it works great).
I believe it at least primarily the dosage I was using simply wasn't enough to battle whatever it is I'm infected with. After using some 4x strength (4 grams of the hth pool shock in a gallon) for a couple days, then using the calculator I linked said to use about .25 grams for 30 gallons to produce about 2ppm chlorine so I tried that 3 days ago. Just changed my res today and everything was clear, even the wavemaker pump was 99.9% clean other than 1 little piece of turd hanging off it (was actually a hair with a little slime on it). Even the little suction cups under my pump were clean which is usually always a little slimy when I change out my water.
I gave it a dose of h2o2 @2ml/liter before emptying my res just to give it a 1-2 punch and will probably give it 1 more dose of that and wait 24 hours to add chlorine. I'll attempt to add .125grams worth for what is probably 35 gallons right now to achieve maybe .8ppm chlorine and see how that works now that I've cleaned it out pretty good.
P.S. Using the calculator I determined that the dosage on the original post would only be about .186 ppm of chlorine. According to the calculator, you'd have to use 5.38 grams to make a gallon of concetrate in order to achieve 1ppm @ 1oz per 5 gallons. Use what you feel is right. I'm still not sure what to think, most people try to remove chlorine from their water not add it, but I've yet to see any negative effects, only benefits.
you should not be trying to make concentrates from calcium hypo. im not sure why you would waste your time doing this... do you not have a gram 100mg ish scale?
in the past, i would just take a small pinch... probably several grains of rice worth and rub my fingers together inside the res. its probably like an eighth of a gram of calcium hypochlorite.
if you dont have a scale, and insist on germanic precision, then just use sodium hypo... its been stabilized by lowering its ph substantially with lye or KOH. regardless of this added base, given the quantity added to your res it will not appreciably alter your solutions ph.
just get the cheapest non scented non surfactant/gelled sodium hypo.
i think you are vastly over estimating plants sensitivity to hypochlorous acid.
