Hello I have a 40 gallon aio tank. I run tunze 9004 skimmer drop 1.2x scrubber and purigen. Thats all. I have 8 fish. Algae scrubber is in for 7 days and it is clean as new. 12 hrs light schedule 24 hrs bubbles. Black screen is being used. . I was away for 4 days so I had auto feeder for pellets twice a day. I left a huge nori piece before I left. When I came back glass was covered in green slime algae with some white dots. Phos went from 0 to 0.26 nitrate from 8 to 16.
Shall I continue like this or make a change to start the algae scrubber? My tank is 3 months old. Rocks are covered with lush green color no hair algae.
Phos and nitrate is no where near where I would like to operate. Normally i ran nopox but because I was away no nopox. I thought it would help to jump start the scrubber but nothing on it.

Appreciate any comments to help start the scrubber. Tomorrow I am planning to start on nopox again.
