Far cheaper than water chillers, air pumps, bubble rocks, water falls, air, aeration and all those chemicals when you catch a dose. But, first, you got to think beyond the limits of a DO chart. Can you do that? Easy to make an O2 enrivhment rig if your inclined. Are you a RDWC/DWC pot grower, are you inclined or no?

so still no answer? i hope you aren't paid solely by commission cause you are the worst salesman i've ever seen.

let me guess @J Henry , you are skeered to put up pictures here cause in Lousiana they are tough on drug crimes?

either you got suckered into buying one or you work for them.

i think i know which one is true.

@J Henry

hey how's the weather in Minnetonka today?

what's it about a 12 mile drive to Excelsior where O2grow is located?

i can put your address up too, dumbass if you'd like.

Only ways I know of to supersaturate water with O2 is through heating to boiling, then rapidly cooling, or under pressure.

Henry's Law... increase the FIO2, and keep the nutrient temp at room temp, ain’t nothing to it. Fish hatcheries have been doing this for years with supplemental oxygen in intensive recirculating cultures. I’ve never tried the boiling/cooling and pressurizing deal, sounds real complicate to me. Maybe that’s how Dr. Pepper sterilizes and bottles their sodas that are supersaturated with gas.

FI02, as in the carrico index, relating to 02 saturation in blood. How's that apply to this?

And: https://en.m.wikipedia.org/wiki/Henry's_law

Deals with supersaturation under pressure. Not at atmosphere.

Yout can't have 02 supersaturated water at atmospheric pressures or temperatures.

Fish farms are using air pumps/compressors with stones to supplement O2...dont even try to say different.

I should add, I put this amount of chlorine (bleach) in my top off res. Not directly into my RDWC. So the actual amount of chlorine in the system is much less. I can smell it in the top off res but not in the system.

@rkymtnman & @redi jedi

How much clorox do you use per a gallon of water? It sounds like the simplest solution for a sterile res. Do you guys always have some in the res as preventative or just when it gets nasty?

i have been using dutchmaster zone (ready to use chlorine additive) at 2mL/ gallon in my rdwc and drain to waste hempy buckets for about 3 years.
my bottle is almost empty so i'm going to use HTH pool shock (49% chlorine i think) at 0.15 grams per 10gallons water. will come out to 2ppm chlorine. i think plants can handle up to 5 ppm before they get problems. that pound bag i got at walmart will last years and it doesn't degrade over time like liquid clorox does.

I'm currently using pool shock as well. I bought a 5gal bucket for 50 bucks and that will last me until I die..

That's bull...
Sure you can if you chose too… if you can think beyond the limited boundary of that little DO chart. If you can’t or won’t think beyond the limits of the DO chart, all this will be a total waste of your time.

So here you go, call Pentair (877) 347-4788 1 877-347-4788 1 877-347-4788 and ask for technical support. A tech will help you understand how Henry’s Law works in reference to gas saturation and supersaturation in water. *** This is a free call, nothing to it. Learn how gas chemistry really works, how to exceed the limits of the little DO Chart, how to manipulate FIO2 and gas partial pressure.
