how to transport algea from old to new screen

[varke]

I am starting my new scrubber with a different screen size so I have to use a new screen.
The new screen is hanging in my sump for two weeks and gets a little light from my scrubber there is some cyano on the screen now what is the best to do hang it in like that ore some pieces of my old scrubber screen attached to the new one and start it up like that because my sps dont like it to much if the scrubber needs 2 ore 3 weeks to start up.

Thanks

The best way is to install strips of the old screen on your new screen. Make each strip only a few rows wide and alternate sides, leaving a gap on the opposite side (like the vertical members of a yard fence). Then attach them with small zip ties or fishing line. This will allow the old screen to continue to grow, giving you at least partial filtration, and then will seed the screen around it with that growth. Let the screen grow as long as you can (10-14 days) and clean it very lightly, with only minimal exposure to tap water (along the top edge, to prevent algae growth primarily). Leave the strips on for at least a month, and take them off a few at a time. You might be able to remove some strips after a few weeks, depending on growth

Thanx Floyd
I will do it like that and post pictures as it grows.

installed last sunday now on friday it looks like this.
for now the leds burn for 18 hours because i need fast filtering for my sps corals.

I think you are getting too much light in the center - looks like it is "burning" (technically, it is photo saturation). If you can, back the LEDs up a bit, do that, otherwise you need to reduce the hours to 9 or 10 per day until the screen gets enough growth to be able to handle the longer photo period. Or, you can put a diffuser plate between the LEDs and the screen and leave the hours at 15-18. This diffuser material is the same as what is used in a fluorescent recessed ceiling fixture. Bumpy on one side, smooth on the other. Bumpy side goes toward the LEDs (it doesn't really matter though).

If you start seeing problems with the SPS corals while you are waiting for your screen to get up to speed, use some activated carbon.

I turned it to 10 hours now lets see what happens.
I am not able to putt the leds further away the are about 5 a6 cm from the screen and the screen is 22 X13 cm with 10 leds on each side burning on 350 ma that is half power butt the green on the photo is on top of the screen where there is no direct light so burning is possible.
thanks for helping.

There is light on that area of the screen, but it is on the fringe of the intensity. The level of intensity in front of an LED is related to the off-center distance as well as the physical distance. So right in front of the LED, it is the peak of intensity, and then it drops off as you go further off center. The level also drops as you increase distance, but mainly because of the light spreading out more. Directly in front of the LED, the intensity doesn't change as much when you increase distance a little bit, because it is a focused point source instead of a spread source (like CFL).

So the light level if probably about right where the green is...

Let it grow 14 days.

today first cleaning after 14 days.
its not much but the grow is dark so i thought it was time to clean.
the leds burn for 10 hours and i putt them from 5 cm to 6 cm from the screan that is max.
the display still looks good and there is a bit of no3 and p04 bilding. up.

Screen after first cleaning.
am i on the right track or not.

[SantaMonica]

Looks great.

As you can see, you don't really need to transfer to the new screen. It actually grew the same on the non-transferred part.

[varke]

Thats what i thougt to.
There is not much more algea on the seeded strips mayby its just as hard for the old algea to get used to the led as it is for new ones to grow.
and for now 7 days growing or 4 days because it is dark grow or and i need to get my p04 down.

[SantaMonica]

Do 10 days.

When I switched ATS out for version 2, I just took a harvest from the old and smooshed it into a nice and roughed up screen with my thumb across the screen. It took off pretty quickly. Tank never skipped a beat during the switchover.

[varke]

Oke i do that in 14 days i go to Egypt to the red sea for 12 days.
do you think it looks good for my holidays how it works for now?
N03 & p04 looks good only still cyano in the tank.

[SantaMonica]

It will be fine.

That is not cyano... it is algae that let go from the screen.

Clean more often now.

[varke]

After my holiday the algea are more spread over the screen and looked better than last time.
Now i cleaned the screen after 8 days and turned the lights to 12 hours and there was more coming of the screen than last time after 13 days.
I would like to have more growth but no3 and po4 are good so it works.
