This is not directly related to peroxide control it is more information related but it adds to the scope of algae control. So I am posting about my personal experience.
So I have added a new tank attached to my main system sump all plumed into one and noticed something interesting. Soon after I set it up diatoms and hair algae grew on the glass and the frag racks that I had added in. Since the systems is all plumed together and all use the same water and I have very low nutrients with little to no problem algae in the other tanks something else had to have contributed to the bloom.
The lighting is different then I have on my other tanks that are attached with a different color temp then I use on the other systems. I was running a 10,000k led lights on this system (vs 16,000K to 20,000K) so I assume color temp played at least some part in the bloom. Since the tank was newly set up it also didn't have the necessary cleanup crew that my other tanks have. Like pods, snails and fish ect that help keep my other tanks algae in check.
As I was interested in what was going to happen I left the bloom be and took no extra steps (except my regular routine) to get rid of it except changing the color spectrum to around 16,000K but I did no manual removal. The algae bloom didn't last very long as my tanks big productive refugium quickly kicked into action causing a bloom in algae eating critters. You could see thousands of them within a few days crawling all over the algae happily devouring it. Within the week all the algae was almost completely gone.
A few things come from this. Nutrients are not always the cause or control of algae blooms as my system is very limited in nutrients. Since I recently added a large amount of new water it changed the chemistry of my tank and however fleeting it was it was enough to cause a bloom in the new tank because of the lack of cleanup crew. So stable water conditions do factor in because if at least some of the right conditions can be met for a algae bloom it will explode. Lack of a properly mature tank with a stable live food source for algae control defiantly factors in. You need to have a proper and healthy food web that can bloom and die off as algae cycle does to help control the problem. So cultivate your food web!
Proper spectrum goes a long way because even if some of the needed triggers for algae are present it can still bloom. As I was able to easily change the color spectrum towards the blue it helped limit the usable light the algae wanted for continued growth and coupled with cleanup crew it was easily controlled.
One big plus side to this little experiment is my main Reef tank is mostly hard corals and because of the extra available nutritious food explosion I had a big growth spurt. Especially with my SPS.
