@Moe.Red alright don't hate me, but I pulled the trigger on going hydro sterile. Before I show the financial math, I'm convinced in my head that small micro doses (every hour) of h202 won't be that "harmful", or maybe radical is a better word in this sense, for the system.
I bought a cyclic timer and another peristaltic pump. I will time it out to give 1ml of h202 every hour. Here is the math, help me out if this needs tweaking.
I have 9, 5 gallon buckets in rwdc, I average about a 3.5 gallon fill level, or roughly 30 total gallons reservoir. I rounded down to be on the safe side.
This is all for 3% H202,
Hydrogen peroxide dosing is always listed in diluted form.
I read that a moderate dose is 3ml of H202 per gallon, which should be repeated every 5 days.
Recommended dose
3ml / gallon every 5 days(it is active for 4)
I have 30 gallons reservoir.
So,
90ml H202 every 4/5 days.
If quartered, that comes out to 22.5mL/day
Or about 1ml/hr, that is an easy goal to achieve in pump and timer. Ideally this will keep H202 at low enough, constant levels to kill just enough pythium for a great maintenance free system. No cleaning drip rings hopefully.
So for the costs...
If we figure 1mL/hr that's 8760 mL of 3% H202 a year.
I just bought 128oz of 35% food grade H202 for $50, free shipping. That will make (11x math) 41639mL of diluted 3% H202. Or enough to last me 4.75 years at a cost of $50.
As far as the controversy behind sterile vs live, for me it's just about being stress free for me. I'm sure I'm only a couple tweaks away from getting live to work, but I'm tired of the guessing. Small amounts of
hydrogen peroxide do exist naturally, so maybe my system of small micro doses isn't that unnatural...

Idk but in the very least we can call it another experiment that might help someone else in the future.
