Jnad's UAS test

Hoping for green... :)

Yes i hoping for green, but have just checked the screen, and there is not any big improvement in growth, just a little.

Cant really figure out what to do: It looks like the screen is divided in two when it comes to growt. The screen area in front of the light is becoming slimy with a light brown color. The top area on the screen where there is no light, only daylight from a window is the area that has most growth. But this growth is dark brown, there is some change in this area though, there is some few treads of long green algae appearing in this area of the screen. It is somewhat strange, the area with no light seem to have most growth??

If you look at the previous pictures you can see the the screen is divided in two, dark brown on top, less brown and more slimy where the light is.

The light is on 12 hours.

Try 9 hours, or less wattage.

Hello!

Have run the lights 9 hours on fore some days now, did take out the screen today just to have a look, and i actually see some few strains of green.

I have a couple of questions:
1. I have today bought a plate of light diffusor and placed this in front of the leds. I think it is the same type of diffusor others have used on this forum. Should i continue with 9 hours light periode or should i increase the hours when using this diffuser??

2. Should i clean away the dark and yellow algae on the screen or is it best just to continue letting it grow??

I have also changed the air tube/pipe to one with bigger holes that give bigger bubbles, this make it possible to increase the amount of air a lot, the water flow also increases with the air amount. I do think i have used too small bubbles, the bubbles was almost as small as in a protein skimmer.

Have now bigger bubbles, more air and more water flow trough the scrubber.

I'd clean the screen off.

Try different hours.

Screen cleaned and light set to 13 hours on beacuse of the diffuser mounted today :)

Hello!

Finnaly it seem to be a progress in growth, this is 5 days of growth after i changed to bigger air bubbles and put in a diffuser in front of the light. The light still looks like it is too strong, i wil consider to cut the hours to 9 hours on.

Mostly green on top and bottom of screen, and some tint of green color in the middle:

That does look better!! I am wanting to put a diffuser on mine as well.

Yes, i think the diffuser was the main factor for better growth. When the screen beacome "i hope" compleatly green i will try the tube that making small bubbles again, just to see if bubble size matter. The tube with small bubbles did also run silent, bigger bubbles make some noise.
