Zooxanthellae and the hard coral-Zooxanthellae are the symbiotic algae that live within the hard or stony corals. The symbiotic relation is based on the coral's inability to generate sufficient amounts of food and the algae’s ability for photosynthesis and converting chemical elements into energy. - mutualism
The remora and the manta ray-The benefits to the remoras and remora for living in such close association with their larger hosts are clear, but there is a debate about whether the manta rays receive a significant return in benefits from these relationships. - mutualism

Answer:
You could check the pH!
Explanation:
This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.
So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.
