So, there's one more thing I've been wanting to get going again that I just haven't gotten to since setting up my 180 is some form of algae growth and harvesting. I used to have a hob refugium that I would light at opposite hours from the tank and just let whatever wanted to grow back there grow. Then I would periodically harvest stuff out of there.
Today I have spent way to much time looking at algae turf scrubbers that was making my head spin. I wish I had the time I used to have as a water fall type seems very easy to setup. But it took me about a year to just get a simple T adapter and turn on my ozone generator.
Basically I just want to be like PaulB and this is just one more thing that's on his tank that I really like. His setup uses an algae tough to grow algae but I don't have the length in my sump area he has on the back of his 100.
With my sump room now adjacent to our guest bedroom I need to be aware of noise and light leaking over threw the door which has slats on it for ventilation. So if I want to do the alternate light schedule again, which I want to do, I have to make sure what ever I do doesn't allow for light leakage into that room at night. So just tossing in some chaeto and lighting it up won't work so well. I also dont have room for that in my sump unless I take something out which I don't want to do.
My first chamber is my drain, probes, and filters which right now is my skimmer(ozone) and GAC, and where I pull water out for the AWC. Second biggest chamber separated by a baffle from the first chamber is the reversed under gravel filter covered in dolomite and then a bunch of rock covered in sponges, various worms, dusters, more and more pods and what ever else grows in the dark. This is also where I add my top off/kalk from ATO, vinegar, and new saltwater from AWC and a couple ehiem jager heaters. Then several baffles go to my return section with just the mag 1800 and several float switches and a pressure switch to check high low sump levels.
I looked for several ways to add in the algae harvesting with out disrupting what I have going already and not have any bleed over of light and the waterfall algae turf scrubber seems perfect. Now to just make one or get one made. I'm looking at getting one made as I 1) just don't want to think about it anymore as I already spent to much time on researching this 2) time or lack there of
I found one I really like due to being compact, able to fit on top of the sump not messing up what I've got going on, and made to have minimal bleeding of light. Plus it seems pretty efficient at growing algae.

Its really not more then I just like algae and always have. I don't think a healthy tank or any body of water should be with out it. I like some in my display tank as well but it just doesn't always cooperate on where you want it to grow there. And it eventually dies out.
I would keep doing everything I'm doing now but I would cut back on the carbon dosing. I'm right around 100ml per day now and would cut that in half. I don't use gfo unless I have too and growing algae would just reduce that need even more.
Right now the GHA I had is basically brown goop now and receding and the cyano is dying off. I never did put my hands in the tank this time around to pull anything or blast anything away.
Here's some updated pictures of the die off.
The purple cyano is turning gray
Right side is pretty well cleared off with a few patches of cyano fading away too
The patch of cyano on the right side about to go away
Very top of right side with cyano about gone
Here's the left side which was the worse area where what's left is this brown goop
Basically, just have to have patience.
