Having trouble loading files right now. I'll try again shortly.
The first photo is three months ago at 18hrs a day with the lights in the factory delivered setting. The photo is a litter greener than in person where it is more of a dead yellow/grey color. After that photo I changed the lights to 12hrs on 12 off per a recommendation you made to someone else.

The next three photos are after a few months of 12 on 12 off and about a half cube per day. in the third picture I'm trying to show how mealy the algae is when I scrape it in case that tells you something.

The flow rate is about 240gph (based on holding tubing at L2's inlet level and filling a graduated bucket to 2.5 gallons and doing the math). I tried turning the Radion on and it grew the same yellow/grey algae on the DT glass with in a week or two.

More light? Less light? More food?

Thanks for any help.

Hello All! I've had my ATS running for around 5 months and still not getting thick algae on it. I am getting mostly bubble algae and red algae. Minimum of hair algae.

I am happy that there is really no nuisance algae in my DT but are there any pointers you can offer to get thick hair algae? Should I be worried about the slime and bubble algae growing on my ATS?

Thanks

What size screen? Flow rate? What type lights? How much do you feed?

Lot's of variables. If you do not have DT algae there is probably nothing to be concerned about but the best way to know if it is doing its job is the answer to this question:
What are the levels of NO3 and PO4- the nutrients?

Just cleaned my screen and noticed something interesting. The 1/2 of he screen closest to the water line was nice and thick in algae, the side furthest away was just slightly brown.
Maybe not enough water flow?

Looks like it needs a lot more light, more often cleaning, and a white screen instead of a black one.

Some is wrong if there a bubbles growing. Probably not cleaning often enough.

Not enough air/water turbulence. That's what grows algae quickly, and it's only at the air/water interface. There should be no screen too far below the waterline, unless there are air bubbles on it to make the air/water turbulence.

Thanks SM,
I had the light at 18 on 6 off. Should I go to 21 on 3 off or 23 on 1 off? The screen is white I just didnít remove enough algae to show that.

Instead of completely scraping off the algae, I would do a less aggressive level of cleaning. I'm not sure how long you go between cleanings, but what I would do here is is a partial cleaning at around 5-8 days where you just rinse the screen in tap water while rubbing it with your fingertips. You might make a few passes with a soft toothbrush to loosen a bit more, but that almost looks like you are accumulating detritus on the algae (which is not uncommon) and that should easily rinse away.

You could also do a partial scraping, leaving 50% or more behind.

But the biggest question comes down to this - how is your tank doing? Any nutrient or algae problems?

You are not feeding a ton, so the scrubber is a bit oversized so I don't think I would try to push it harder by adding more light or flow, I would leave it where it is and just let it grow more.

This is typically due to a flow differential, either the flow is a bit too much and this is causing it to arc across the screen (heavier on the far end) or it's too low and there's not enough on the far end. Whichever it is can depend on your specific system sometimes.

Either way, it should eventually fill in with the same type of growth across the entire screen, but the screen needs to be mature for that to happen, which can take a while. In some systems, it doesn't matter, it'll just fill in right away. Other systems can take a while.

In your case I'm guessing the flow is on the higher side so the close side is actually getting a bit less flow (the water is arcing). The logic says that for you, at this point, a bit lower flow works better - which can be the case for a new screen. So if you are getting that arcing and the water is piling up on the far end of the screen, reduce the flow just a bit until you get more even flow.

jalisco - do NOT listen to SM's advice here. He has clearly not read your other posts or looked close enough at the pictures you posted.

#1 your screen is not black

#2 you are not feeding enough to warrant more light:

^^ 12/12 should really be just fine, and unless you have a persistent nutrient issue or tank algae issue, pushing the scrubber harder just to get GHA growing for the purpose of only achieving "the right type of growth" is not necessarily the right focus.

#3 you don't need to clean more often in the "scraping" sense of the word, see my post above regarding this (interim cleaning, rub & rinse, etc)

Just to be clear, when you say "water line" are you referring to the input water source line or the level of water that the screen is sitting in?

"water line" can be interpreted in 2 different ways. I interpreted this as the input water line, SM interpreted it as the water level the screen is in - so I want to make sure I answered the right question in my previous post. If it's the other water line (level) then the answer is indeed different
