Using 35% food grade h202 in a hydroponic reservoir

I've been having issues recently with my holding reservoir (32 gallons) going rancid in just a matter of days recently. What I mean by that is there is clear slime on the air lines going to the air stones and on the water line of the plastic trash can. I even have a pond pump in the bottom to add circulation. My water temps are around 76-78 and I suspect that might be my problem. I then started reading about adding 3-5ML/gallon of food grade hydrogen peroxide to my reservoir to keep bad bacteria from growing. 1 treatment is said to last for 4 days which sounds nice. I can get 5 gallons of 32% from https://www.chemworld.com/Hydrogen-Peroxide-p/CW-54-5.htm?keyword_session_id=vt~adwords|kt~|mt~|ta~57098673493&_vsrefdom=wordstream&gclid=Cj0KCQjw3JXtBRC8ARIsAEBHg4mpK0xDwgfBKEUbsToP1hhyQwhF1pfYG2lamRmj5fKEriSRmlDB5-IaApUTEALw_wcB, but I'm not ready to punk down that kind of money yet. Possibly on my next harvest.

Anybody else have experience with using concentrated food grade h202 in their reservoirs? I do water to waste hempy buckets and I'm now mixing my nutrients on demand the day I water, because I had to dump several reservoirs recently full of expensive nutrients at least until I figure this out. H202 seems to be he answer. I'm sure as hell not buying a chiller. Too rich for my blood. I'm just trying to keep the bad shit from growing in my reservoirs. I have a ridiculously overpowered air pump running to 2 large air stones in each reservoir and a 400GPH pond pump in the bottom of the 32 gallon reservoir for circulation. I really think it's just the water getting too warm.

Would using RO water help solve this?

Once the problem is established best if you dump it

What is the size (GPH) of your pond pump AND how long do you run it?

Too much back pressure on the air pump will make a lot of heat.

400GPH 24 hours/day to circulate the liquid at the bottom of the reservoir. To be fair, I got the pump after I had a couple of contaminated reservoirs. A friend suggested it. I have noticed the water is warm. Could it just be my basement is warm and making it easy for pathogens to grow?

I got some 35% h202 for $18 and change this afternoon. 1 gallon to be exact. Food grade. This should solve the issue long term. Also grabbed some battery acid from the local parts store on the cheap. $11 if I remember right. I have to lookup the recipe again but I think it's 1 cup of sulphuric acid to 1 gallon of distilled water. The result is years of PH down on the cheap. Threw in a couple pics of the current grow. I had 2 600W Metal Halides above the canopy, but it light bleached a few branches and some leaves expressed their displeasure with the intensity. Temps were only 77-79. They just couldn't handle the intensity, so I removed one and am running 1 600 MH for the remainder of veg. I'll let her bush out the screen another week and then flip to flower. I'll be able to tuck branches for 3 weeks as the stretch goes on which will fill out every nook and cranny of the net.

As a starting point: Research how long O2 remains in solution at various temps

Running the pump 2 hours, let alone 24/7 will heat your rez temps.

32 g rez divided by 400 GPH pump suggests it will provide ample O2 in ~ 10 minutes (if my math is correct)

Now when you know how long the O2 will remain in the rez at the temps you are experiencing you will know how often to cycle the pump

Im guessing 10 minutes on and several hours off, which will lower you rez temp
