I recently purchased an l4 scrubber for a new 180g setup I am building. I am starting this tank fresh and do not have a bio load of fish yet however have added a bunch of frags recently. I started this tank a week ago and have fed the tank a few times with nori or flakefood. I have tried seeding the screen with algae from sabbaths l2 screen 2 times but the algae keeps dying or decaying and turning into a white film... I have attached a picture because I cannot think of a good way to describe it other then a white slime. Is there a way to still get my scrubber kicked in without initiating a cycle on the tank? Right now I am still reading 0 ammonia.
