That's generally indicative of high nutrients. Not quite as bad as the black thin sheet stuff, but still pretty dark. You will want to try and clear most of this off the screen. You still don't want to scrub hard, but you will want to scrape that stuff if it doesn't come off when you just rub with fingertips & rinse)

Looks like a scrubber working great!

Any feedback on my solar experiment? Should I run the LEDs during the night?

Yeah my nutrients are likely super high ATM. I have not done a water change since starting the tank like 3months ago. And my skimmer has been offline for a month. Got a 30" lifereef skimmer ordered, so that should help slow down the nutrients a bit.

I am setting up a peninsula 20, and I am trying to find a way to put an algae scrubber In the middle chamber. it's to small for a hog or drop style from Santa Monica. I don't want to externally plumb a waterfall type, so are there any ideas that would work in the middle chamber?

Put an airstone, and screen with strings attached, in there.

Are we talking about an in-tank scrubber??!! Yes.. finally, we've arrived!
That's exactly my plan on my new tank. I use the bubbles to create a wall of algae that the fish can't access... then I turn off the air and let them graze when it's long enough. Sequestration and recycling in-tank! I thought it was only possible on big tanks like mine but if it's feasible on small tanks, that would rock!

@karimwassef, I can't tell if you're being sarcastic or if you haven't heard of the UAS

Upflow scrubbers have been around for a while. It's putting it inside the display tank that I think is novel and I am excited to do it.

Haha, I've heard it said that it's lonely at the top. You've done a lot of cool and innovative things. Keep rolling!

What do you guys think of sticking the roughed up mesh sheet into a lighted reactor?
I saw a guy do it on YouTube and he has success. It's pretty much the same method as a chaeto reactor except you have the mesh screen in there. Sent from my SM-G955U using Tapatalk

Here's the video https://youtu.be/eigiaiZWtfc
I know in the video comments Santa Monica was concerned about air flow into the reactor. My idea is to add an air valve into the water input of the reactor. A venturi concept like our skimmers What do you guys think? Sent from my SM-G955U using Tapatalk

I've done something like that before. The problem is bacteria. Without the air mixing, bacteria set up shop and in some cases totally overwhelmed the algae... and I ended up with a cyano reactor instead of an algae reactor.

Sounds like it's competing with the tank algae, what's your DT lighting type, intensity, schedule, etc?
Do you have a lot of corals? What are your water params? Offhand I would say, intensity is OK but with the DT competition, you might not be able to push it much harder based on that growth color. But, you should be able to extend hours. I would go to 16 or 18, same intensity (4) Then I would consider adjusting the DT lights in some fashion, this will depend on corals, but essentially making is less algae-friendly by backing them off somehow, and let the scrubber out-compete it. Make a small change for a start and see if that shifts growth to the scrubber. Don't make a huge change, that can shock the system. Just a test and observe results (10-20% reduction, etc). If it seems like that makes a difference, then up the scrubber intensity and flow a bit and observe, then continue down that path.

I also have to wonder if the algae growth on the rocks is a result of built-up nutrients over time, that is now leeching out. That's the tough one to beat when you have encrusted corals, it just takes time to leech everything out (sometimes, 6-12 months). The nutrients and light are right there on the surface of the rock, so the algae gets first crack as it's getting released from the rock structure. Nitrate and phosphate levels would be good to know. My guess is that they are reasonably low, if not zero.

The issue with leeching, IMO, is that it's 2 stages (potentially) - short term and long term.
The short term is the soft surface that dissolves rather easily. Can't recall the term for this. Anyways, it still takes time to leech this off so a short treatment with water that is heavily filtered with GFO or treated with LC will pull out the phosphate out of the water, but not the rock - unless you "cooked" the rock, and regularly treated/filtered the water. The long-term is where you have crystallized calcium + phosphate deposited on to the rock (this happens rather easily in the tank). This can only be released by acid treatment (pH must be below about 7.0) or in-tank via bacteria (PSBs = phosphate solublizing bacteria). It's a theory that fits the results on PSBs. Bacteria and algae work symbiotically to "cleave" phosphate from the rock. The bacteria create a highly localized low pH area that breaks the bonds. When the bond breaks, that pH jumps back up, so it takes a long time for a large amount of rock to get "cleaned up" when this process is happening. It's possible that "cooking" the rock (for months) puts this process into overdrive. So the net is that if you have old rock that has built up a lot of waste over time, it can take a long time to reverse that. There's actually logic in "burning it out" by increasing the DT lights duration/intensity...but that usually means, lots of hand-harvesting, and risking corals getting ticked off.

I just always assumed get my inputs and outputs inline (thus my effort on the ATS) and eventually things will stabilize. I have 3 tuxedo urchins and a scopas tang and keeping up is a laughable proposition at this point. My plan is get the ATS maximized, if it can't keep up it's either bigger ATS or big fuge with big lights time.

Thoughts on using a 20W LED flood light that uses multiple lights vs. just one to make the total wattage.
For example, between the following: https://www.lightingever.com/20w-sup...lights-ww.html and https://www.lightingever.com/1600lm-...049-ww-us.html

I feed quite heavy - my tangs eat at least a 4x8 sheet of Nori daily. I have a ATS and also dose carbon to keep NO3 and PO4 under control. Last reading were 5 and .07 My last harvest after 6 days was 400 grams of algae. See pictures. My screen is 9x10
