Tank is a 90 gallon reef tank setup for about 1.5 years now. I run a fairly simple setup with a skimmer, brs reactions with gfo/carbon.
Tank is doing pretty good utilizing water changes about 1x per month, same with gfo/carbon. I do have a few patches of hair algae on my rocks and overflow which is why I wanted to start using an algae scrubber.
So attached is a pic of my surf2 after 10 days with the black cloth on (18hrs a day). You will see that it pretty much looks like the day I bought it.
My tests for nitrates usually are around 10, and phosphate never gives my any readings. Maybe its all being consumed by the algae or bound? Just want to know what steps I should take next to get some algae growing. Thanks.
