Turbo's Aquatics HF L4 scrubber

Thank you very much for this detailed info.
I will do as you said, and keep posting my updates.

 

- Day 25 (2 days from light cleaning).
- Photoperiod is 9 hours by night .
- Flow is 500 g/h.
- No3 = 2-3 ppm (Salifert)
- Po4 = 0 ppm (Salifert)

So, I have done light cleaning two days ago, and I have removed as much brown growth as possible, leaving green growth behind. I must say that green growth had pretty strong foothold on the screen, so I didn't removed some of strongest GHA from screen. Now, I am getting some red algae patches in past two days.
Even while I am feeding a few times a day with flakes, frozen mysis and dry pellets, my No3 and Po4 are steady for four weeks. Works great.
Algae on photos looks much brighter because of flash, in real life they appear much much darker.

 

- Day 27 (4 days from light cleaning).
- Photoperiod is 9 hours by night .
- Flow is 500 g/h.

 

Outstanding, I was looking forward to this. Algae look really dark green for sure, and I have some brown and green algae outbreaks in my DT. I am limiting my light to cold spectrum, with 9 hours photoperiod in DT, but some of my corals surely need more than 100 PAR for 9 hours for sure. I can see that.
How many more hours you suggest for scrubber?

 

Thank you Garf a lot.
I will keep posting for sure.

 

OK, so I realized that my sump space below DT is really really dark, and that I used flash with my camera in order to get photos of my algae really close. That's why algae appeared so green (powerful flash), from the beginning. In real life, algae is pretty dark, almost completely black.
I decided to look at algae under room lighting, so I have removed screen and took some photos under room light, and camera+flash at different distances.
Algae looks really dark an gooey, and I wanted to remove that layer. Surprisingly, this dark hair algae was anchored near the top of the screen, and long string was covering entire screen. I have cleaned it, but I left some strings on screen at this point.
I am a bit confused that I am getting this amount of really dark growth, with just 2 ppm of No3.
I hope, that this cleaning will make some more space for new green growth soon.

 

Yes, that is squeezed algae on that photo.
I have now 12hr photoperiod as Garf suggested, but since than you can see some new detailed photos. Should I reduce to 9hr or leave it on 12hr?

 

Thank you very much.

 

- Day 31 (4 days from full cleaning).
- Photoperiod is 12 hours by night .
- Flow is 500 g/h.

I don't know if this is because of screen maturity, or 12hr period instead of 9hr period, but this scrubber really picked up recently. You can clearly see that I am getting full clean green growth now, instead of mixed from before.
Four days from full cleaning, and I can't be more satisfied!

 

- Day 33 (6 days from full cleaning).
- Photoperiod is 12 hours by night .
- Flow is 500 g/h.

Algae is growing well, and I can clearly see good progress.
Only new thing that I could see now is that cyano is spreading from one edge of the screen. It started as small patch of brown algae, but now I can that see much more space is taken.
It could be because this tank is still very young (two and a half months old), I am not sure.

 

- Day 34 (7 days from full cleaning).
- Photoperiod is 12 hours by night .
- Flow is 500 g/h.
- No3 = 5 ppm

Here is my update after 7 days from cleaning, and now it is time for another cleaning.
My Nitrate is a bit higher for 3 ppm now, but that's what I am aiming for after heavy feeding for two weeks. I need at least 5 ppm Nitrates for my softies, and I am there now.
Fat fishes and happy corals so far.

 

This is how I clean my screen. You can see how much strings I leave on screen, in order for new growth to have jump start.

 

Absolutelly. I was surprised how strong this time algae is holding on.
Also, I would like to say that this time there is completelly new smell. Instead of previous "dirty beach" smell, today there is clear "vegetable" , "spinach" smell.
