I got S.R.K. (dry reef rocks) from the aquarium. It looks like a lot of trash. I read that everything can be cleaned with hydrogen peroxide. What concentration of hydrogen peroxide should I use (35%, 60%) and in what proportion should I dilute it with osmosis? Can I pour in pure 35% hydrogen peroxide? I would be very grateful for any advice from those who have used this method.

I conducted the procedure twice. The first time I took 35%, poured 5 liters into 50 liters of osmosis (that was the capacity I had). I placed the pump inside the barrel. It bubbled actively for a couple of days, then calmed down after a couple more days. I soaked it in osmosis with the pump for 2 weeks, replacing the osmosis water every week. Then the second round: I took 50% hydrogen peroxide, with the same proportion. Again, it bubbled actively for a couple of days, and then calmed down after about 3 days. I soaked it again, changing the water once a week. Phosphates were around 0.5 at the end of the soaking week. Judging by the process, it would be correct to repeat the procedure with hydrogen peroxide again.

No need. If you care about your eyes and don't feel like cleaning everything up afterwards. The above-mentioned method works quite well.

who else has used hydrogen peroxide??

Here is a step-by-step recording of my processing method for those who are interested.

I tried soaking S.R.K. (dry reef rocks) in hydrogen peroxide, and I am satisfied with the result; the photos show the outcome. I soaked them as follows: 1. I took the S.R.K. (dry reef rocks) and rinsed them with a pressure washer. 2. I poured 20 liters of osmosis water into a container and added 3 liters of 35% hydrogen peroxide, set up a flow pump, and left it for 10 hours. 3. After that, I wanted to clean the sand, so I added 20 kg of sand to the same water. The next day, I drained the water, rinsed everything in clean water, and filled the container with new clean water. After 2 days, I tested for nitrates and found 0, and for phosphates, I also found 0.
