Left hydrograde h202 in aerocloner

So I was going to use my aero for some cuts a few month back, I cleaned it out put some hydrograde h202 and let in run for a few days to clean it out. I ended up using root plugs to root my clones instead of the aero so I unplugged it, thought I dumped the water out, but forgot too, so it was sitting there for a few months, cover on, fulled with water + h202- Was wondering if this would cause corrosion of the plastics including the subpump and aerocloner res itself? Figured it would and I should just toss it out, I have a few more clones anyways.

h2O2 will just brake down into h2O in solution. I put zerotol in my res with nothing else to keep the lines clean and it works very well.
I would soak it run it and repeat. On the other hand if you have some cuts that you are worried about a new pump is not that much.
To be clear the res I am talking about is 45 gallons and I ph the water and add 2.5ml of zerotol when I top off the water.

You'll be fine. Just wash/rinse well. Warm water, soap, and elbow grease!
