Yeah grab a 10# bag of lemon powder (ascorbic acid) for 25$ and youll have enough ph down to last the rest of your life.
It brings it down. A pinch is enough to take 30 gallons from 8.5 down to 6.5 ish. Shit is potent.
I too can only find the HTH granule version of Pool shock in my area. 65-70% versions. Wondering if this works the same? Has anyone used this particular one? or are they using 45% powder versions?
As long as it contains just Calcium hypochlorite it's the same stuff.
One adds Calcium and the other adds Sodium.
I'm in the same boat as you atm. Im wanting to go sterile but not sure how to go about it. Hy-clor super shock is all we have here too. Have you used it? If so did it work and what were your measurement. Thanks
If you're unable to figure it out you can always use 35% H202 @ 3ML/gallon. Or Southern AG's Biological Friendly Fungicide @ 1ML/10gallons. Same stuff as Hydroguard, but more concentrated. Best of luck!
We don't have southern ag here either..
I add it with the water as the 30 gallon reservoir is filling with water from the RO unit. I water every 2 days and I don't add my fertilizer until right before I water. The BFF is highly concentrated. Sorry I'm no help on the pool shock. Checkout icmag. I think I remember reading an article over there about pool shock for sterile reservoirs. I actually bought a bag of it. Never used it though. Wound up going with 35% H202 then BFF because it's even cheaper. If you can get the pool shock recipe worked out that would certainly be the cheapest.
Sounds sketch, would pool chemicals pass testing?
I think you need better understanding about chemistry. Calcium is essential, chlorine is tertiary nutrient for plants. Both are very common in nature.
I'm sure i do
Probably calcium chloride, calcium carbonate and calcium hydroxide left from manufacturing. Mine is about 60-70% pure. Best of luck!
