Set at full blast 18hrs
It looks like it is filling up one day later
I’m not going to touch any setting and wait to see the result
Yup, see what happens. When you do your first harvest, make it a very moderate one. Pull by hand and see how much comes off. Try to leave a decent amount on the screen along the top edge as that will migrate downward. you can be a bit more aggressive along the sides and bottom edge though.
Ok thanks I will try that
Wow the L4 is back in action with a vengeance.
On Monday I wrote everything is set at full pump, and light intensity. But Light hours is set for 20 hours.
Very nice, good recovery! Always good to try. I would still try to leave a good layer behind when harvesting.
However if it does come off easily - don't worry. One of the things I've learned is that when algae doesn't have to stay attached, it won't anchor strongly.
In the case of my scrubbers, or really any unit that allows 3D growth, the weight is taken off the growth mat. Add in the false bottom, and the algae mat becomes a mass that is rather self-supporting, and it stays in place (the false bottom keeps it from getting pulled down the drain) so it doesn't "need" to attach strongly to the screen.
I've seen this effect in multiple versions of my scrubbers, I'll pull the screen out and the the lower half comes out pretty much clean (but not white...looks like it's been scraped), the algae stays in the box.
Yes you are right I have noticed that too. The algae sometime accumulate from the bottom and fills up gradually.
Wow is all I can say
After cleaning it(pulled by hand) this is how it looks.
Recovered well, thankfully!
Well, usually I clean my screen every Wednesday. I left it for 11 days, I noticed the surface that is exposed to the light started yellowing. That is not a good sign right!!!.
That's actually not a terribly bad sign. I get that when I let it go for a bit too long, but for me that's usually more like 18 days, that's monster growth for 11 days!
This is what happen when one forget to plug in the water pump to the scrubber.
Nitrate is still low after a week of no scrubbing. That’s good news.
Oh no, not again!!
Screen maintenance and repair, in use since September 27, 2016.
fwiw, i am using strong led led, i used to diffuse them with plastic (semi-clear) but from the heat the plastic would end up shredding into pieces. So i came across this Teflon sheets that i am using as diffusers (just sharing)
Without the diffuse, the algae scrubber would have hot spots around the leds where there is little growth or none at all.
