URGENT! green star polyps issue

[acepumping]

hey. i think salinity is pefect 1.025 is ok. i usually have 1.026 but the corals love it better at .025.. as for the nitrates, they were wayy too high so i did a 30% change and continued to dose.
i started dosing 2 weeks ago and they were fine for te first week. my nitrates have not started to drop
yet. i started pellets about 5 days ago and will continue to dose until i see a bit of a change in nitrates with out doing another water change, then i will stop carbon dosing and continue still with microbac 7..
it seems to
me that some diatoms were building on it so i gave a lit scrub on it. i have 4 diff sections of gsp. most r closed acouple are open, thats what disnt make sense. lol
btw, i started at 100 ml of pellets, very slowly going to add. my
net water volume is 65 gal with sump and all.

one thing i dont get is how do you know when your pellets are reducing to smaller amounts haha
when do i add more after they are been eating away
