Sterile Reservoir Information
So from everything I can gather from the internets, this is what I got.
To remain sterile, you need to have around 3-4 ppm free Chlorine in your water at all times. Anything 2 ppm or below isn’t going to going be enough to keep things clean, and anything over 6 ppm can be harmful to the plant. Seedlings and clone’s should stay at or under 4 ppm and no more.

Clorox Bleach @ ~8.25% Strength
0.1 ml / Gallon of RO Water = 1 PPM Free Chlorine
Standard Dose at 0.3ml per Gallon of Reservoir RO Water
So if you have a 10 gallon res, you would use 3ml per 10 gallons, every 3 days in order to maintain that 3 ppm free chlorine. If you had a 5 gallon res you would use 1.5ml per 5 gallons, every 3 days in order to maintain that 3 ppm free chlorine.
Note: If you have City/Tap water that is already chlorinated you may only need to add 1-2ppm of free chlorine to your water in order to maintain the proper level anytime you’re doing a major water change or top off(dose the new water). However remember to dose the full amount in between water change/res swap days in order to follow the every 3 day dosing recommendation.
For a Concentrated Solution:
I thought about making a less concentrated solution but I think it’s kind of redundant IMO.

HTH PoolShock @ ~45% Strength
0.1 Grams / 10 Gallons of RO Water = 1 PPM Free Chlorine
Drop ~ 0.025 Grams
Smidgen ~ 0.1 Grams
Pinch ~ 0.35 Grams
1 tsp ~ 4.6 Grams
1 Tbsp ~ 15.9 Grams
So if you have a 10 gallon res, you would use 0.3 grams per 10 gallons, every 3 days in order to maintain that 3 ppm free chlorine. If you had a 5 gallon res you would use 0.15 grams per 5 gallons, every 3 days in order to maintain that 3 ppm free chlorine.
Note: If you have City/Tap water that is already chlorinated you may only need to add 1-2ppm of free chlorine to your water in order to maintain the proper level anytime you’re doing a major water change or top off(dose the new water). However remember to dose the full amount in between water change/res swap days in order to follow the every 3 day dosing recommendation.
For a Concentrated Solution:
There’s a couple ways to do this, but this is the easiest I thought of
Concentrate 1
8tsp of poolshock ~ 36.8 Grams
1 Gallon RO Water
This should come out to roughly 3680 ppm’s of concentrated chlorine.
1ml Concetrate ~ 0.97ppm
Standard dose at 3ml per Gallon of Reservoir RO Water for ~3ppm/gallon.
