Looks good. What king of foods and how many cubes a day are you feeding? Please post pics of your corals and or your FOWLR.

I'm not feeding (much) to my reef pool. Started giving a little nori as a variety to the large amounts of GHA. The reef pool is just leftovers from the cracked 90 that survived the 92 degree test, iron overdose test, and nutrient spike tests.

What is the white string at the bottom made of please?

1.5 mm nylon

Note to SURF2 owners: If your tank is new, or if your tank has low nutrients because of lots of nuisance algae, your scrubber compartment may stay "paper white" for several weeks because the scrubber light is too strong compared to how many nutrients are in the water. This is solved by placing a stocking, screen, colored cellophane, T-shirt, or some other partially-transparent material over the light for the first month. After growth covers the white textures and strings in the compartment, you can remove the material from the light and get back to full-power growth.

Thanks for the heads-up. Would this nuisance algae problem also apply equally for someone running successful NO3 and PO3 filtration? For myself that means a productive waterfall ATS. So I've got low phosphates and nitrates as I begin to use the SURF2, just as I would if I had a nuisance algae problem.

Also, if too few nutrients in the water column can create a need to temporarily reduce the light in the scrubber, and if abundant nutrients can cause months of black growth (as described in the SURF2 manual), then what are the conditions that give rise to solid, green algae growth in 14 just days (as found on the SURF2 product page)? Or put another way... both a lack - and an abundance - of nutrients can cause delays in establishing a productive, green algae supporting SURF2. So what's the sweet spot required to get one up quickly?

Thanks for the support.
