Now the No3 V bonce too fast and kind of out of control, even I stop both Nutrition import ( in day 5 ) and start dosing back start 3

no3 in last 10 days trend 1> 1.4> 2.4 > 2.9> 5.6 > 7.4> 10.3> 9.5> 10.7> 11.4> 10.1

also I did 140L water change it’s only lower from 11.4> 10.1
now try to target stable n lower the No3

Three months is a very young tank. You don't have a diatom problem, you've just got a tank that hasn't built up the biodiversity yet.

If I did the conversion right you've got 30 lbs of rock in a 130 gallon tank and only a fourth of it was live to start with.

Post a picture. I think the best thing here is to pull back on all the dosing and stop chasing numbers.

Agree with the above. My tank isnt a year yet and I actually dont test for anything but ammonia, nitrite, nirtate and Ph. Number chasing and dosing in a 3 month tank can create problems in my opinion vs letting your tank mature and gain that naturally. SPS are hard to keep, especially in that young of a tank. Maybe some SPS keepers can help

Well noted will take the picture tonight n update.
So should I try to add more live rock into sump? Or just waiting the dry rock become mature? Thank
