you really need to ID the culprit before you choose the treatment.
I don't see a problem with raising your nutrients a bit as zero is a bad place to be for a newer system but growing copious amounts of algae isn't a good idea if you don't have to. same thing for the UV, at this point you don't know for certain if its even required.
I found a children's microscope kit for $23 on amazon that would suit your issue just fine and if you consider the potential for future coral losses due to dinos it is honestly a steal.
also, I understand your urgency to repair the issue but you still have to keep the tanks stability in mind continuously and act methodically. making a bunch of changes and disrupting the biological and chemical stability of the system just sets you back and is the short road to big problems.
you could probably solve a lot of low nutrient issues just simply by adding some new livestock that create waste and letting the tank adjust.
