I do 40% water changes bi monthly but its still not enough I started using No3pox (methonal) from red sea also going to start using prodibio in a few days and special blend.
Zeostart 3 will likely add more nitrate I would not consider 9 fish a small bio load I keep two fish in a 90 and still run into issues
If your going to stick with the zeovit route I would up the amount of bac/mate/cyanoclean you add to the tank or you could start using vibrant again. Your bateria is clearly not keeping up with or at least keeping in check some of your issues.
Perhaps you added some high phosphate activated carbon to keep orp up as all carbons are a source of phosphate ash
