Pro bio S + bio pellet

[indeco]

Anybody tried this combination before, able to share the result?

Currently I'm still facing high nitrate 30ppm problem with the use of bio pellet. I have tried to skim harder and my PO4 to NO3 ratio is in balance 0.175 : 30

My last guess will be lacking of bacteria, hence will like to try adding Pro bio S.

Bio pellet is running for 2 months.

I would say you just need a little more time for the pellets to work. I have never heard of a tank being bacteria limited and have never heard of someone needing to add bacteria to get a carbon source to work. Not saying adding bacteria won't help the carbon source work better or faster in some tanks though.
