the too many bubbles thing kind of blew my mind... i honestly never knew you could have too much air.

Moe had me cut the air in half to test and almost instantly the ph started to swing upwards, added a little more air and hit the steady sweet spot. i was amazed on how fast the air volume change directly affects the ph.

then yeah the non sterile water was a different problem but very similar results. ph diving every day. at first i thought it was the bubbles again but this time it was the rain water. all very humbling and eye opening at the time.

i'm not sure if this means anything or not but when it was my air volume the ph seemed to stay steady for the most of the day and then late in the day it would crash fast. whereas the water problem seemed to lower the ph consistently right from the time i would add ph up. like if i checked it mid day it would be half way to the low spot i would see at night. but when it was the air volume too high the ph would hold steady for like 18-20 hours then lower in the last four hours of the day.

Yeah, I never would have thought too much air would mess with the ph. I don't have h2o2 on hand so I shut off my 2nd air pump that had 2 stones in the res, and now the ph went up today by .2 I'll probably put em back in but dial the pump down to 1/4 - 1/3 of its capability. That'll give me time to get h2o2 while monitoring the ph and have it on hand in case I end up having to go that route as well. Do u recall what strength, like ml/gal to dose w?

What strength peroxide do you need? 3% is readily available and very cheap.

Yeah, I believe 3% is what is normally used, just am being lazy and don't want to go to the store today lol My wording wasn't that great, I was wondering about how much of it to use, like how many ml/gal

That part I don't know off the top of my head ... AI says the following ... I would verify it before following it though.

• Add 2-3 teaspoons (approx. 10-15 mL) per gallon of waterin your nutrient reservoir.

I use 8-10ml per gallon of 3% rn

I think up to 10-20ppm with test strips

H2O + CO2 =



CO2 is far more soluable in water than o2.

You can reach 100% dissolved oxygen pretty easy with current air pumps and stones. If you keep adding bubbles beyond that point it does nothing to help you, and can add to the co2 being forced into the res. Too much of a good thing.

i used 12% because thats what i had on hand. my system is 25 gallons and i added 80ml to reach about 30ppms of h2o2. i bought these strips to test and monitor.. they're a great piece of mind for me.
