Help attacking Dinos

[Fish Keeper82]

I have acces to a microscope and ive been having a small algae problem that started when i was using Selcon as a food additive for my fish food. I was using it more than the recommended frequency and this led to excess nutrients. This in turn led to a major cyano bacteria outbreak and a minimal Dinos appearance. The Cyano is now completly gone for a couple of months now thanks to red slime remover. I did massive water changes but looks like the dinos that never left is becoming more aggressive dispite less feeding and massive water changes. ( i know this can feed trace nutients to Dinos)
I was not 100 percent sure it was Dino until i looked at some thru the microscope. It always looked like bad diatoms but the picure i saw thru the scope looks exactly like people have posted of Dinos.

Now i need a plan of attack. Ive ordered Dino X but im not sure i want to use it yet. Im kind of leaving the Dino X as a last resort but want it on hand Have read a bit about dosing H2O2 with some success.
Question: Any personal experiances dosing H2O2 and if so any side effects? What was your dose per gallons?
It usually does not look as bad as this but i havent cleaned up the sand just to take some decent pics of it.
I should add it does not seem to be a toxic type since I have not lost any snails an i have quite a few if them.

Wow, it's dino city around here this week.

Please come to the Reef Chemistry forum where there is a long thread with everyone's experiences vs dinos. There are a LOT of treatment options besides Dino X which I personally am afraid of.

Many of us are having some success with the so-called 'dirty method', raising N and P through over feeding, heavy supplementation of copepods/phyto and no water changes. It makes the tank look incredibly ugly for a while but eventually pushes the ecosystem towards green algae and the dinos die out. The other option (clean method) is to remove nutrients extremely aggressively, dose peroxide, add UV, remove the sandbed, etc. Either way I don't recommend doing a tank blackout on its own; combined methods always work better.
