So I can obviously turn off the pump and drain the loop, but whats the best way to dissolve all the sponge and still be able to clear it out and be safe to turn back on once done?

I was thinking vinegar, but Im not sure of what concentration to use since the loop is about 10 gallons of piping.
Don't bother dissolving them. Just get the right sized pipe cleaner, and use abrasion power to remove them.
