sensitivity

I’m so close to being ready to put dwarf seahorses in my macroalgae tank… the dinos are gone, the nutrients are stable, the macros are grown out, and the tank is pest free… except for the cyanobacteria. I know that chemiclean would get rid of it, but I’m worried that there may be repercussions...

Can someone with experience please elaborate on nems when it comes to their sensitivity. I can read allllll day on the internet, but would rather hear it from the horse's mouth. I have waited a long time to add a GBTA to my tank and finally, I did. Juuuuuust wanna see what y'all have to say...
