I would stop the nopox dosing as that states it reduces your nutrients. I personally don't have experience with either of those. The trick is you need to raise nutrients, but you need the bacteria/pods there to to help feed on it. Personally I dosed Apex Pods one week, Tigger Pods the next, then fed live phytoplankton for a week. I overfed the tank a little bit too, no skimmer and reduced water changes. This got more nutrients in tank so my LR could establish more, it provided them a source of food in the phyto. I have dosing stuff on standby for emergency's, but I tried to handle mine without too much outside aid. Only external thing I really added was a UV sterilizer, it did help IMO.
Research on your own, look up what you can, don't take any one persons advise as gospel (esp me) but try to find a good approach you are comfortable with. For me it was pods and phyto, for you it could be dosing bacteria and such, entirely up to you. Many ways to tackle every issue.
Also I meant starving them of their nutrient source. By either having competing sources beat it on NO3/PO4 or reduce light, which will starve the dinos but the bacteria and such won't care as much. I sometimes forget to complete my thoughts.
