Scrubbers are sized according to feeding. Nutrients "in" (feeding) must equal nutrients "out" (scrubber growth), no matter how many gallons or liters you have. So...
An example VERTICAL upflow or waterfall screen size is 3 X 4 inches = 12 square inches of screen (7.5 X 10 cm = 75 sq cm) with a total of 12 real florescent watts (not equivalent watts) of light, or half that for LEDs, for 18 hours a day. If all 12 watts (6 watts LED) are on one side, it is a 1-sided screen. If the watts are divided on each side of the screen, it is a 2-sided screen. This should be able to handle the following amounts of daily feeding:
1 frozen cube per day (2-sided screen), or
1/2 frozen cube per day (1-sided screen), or
10 pinches of flake food per day (2-sided screen), or
5 pinches of flake food per day (1-sided screen), or
10 square inches (60 sq cm) of nori per day (2-sided screen), or
5 square inches (30 sq cm) of nori per day (1-sided screen), or
0.1 dry ounce (2.8 grams) of pellet food per day (2-sided screen), or
0.05 dry ounce (1.4 grams) of pellet food per day (1-sided screen)
Problem rocks: Each 50 pounds (2.2 kg) of nuisance algae covered rocks you have adds 1 cube a day.
Flow or air bubbles is always 24 hours; water flow is at least 35 gph per inch of width of screen [60 lph per cm], EVEN IF one sided or horizontal.
FLOATING SURFACE SCRUBBERS WITH STRINGS: Screen size is the size of the box (Length X Width), and is 2-sided because the strings grow in 3D.
Clean algae:
Every 7 to 14 days, or
When it's black, or
When it fills up, or
When algae lets go, or
When nutrients start to rise

My upflow ats has been working wonderfully.. display tank is like 99 percent algae free.. ( I deff have an over feeding problem)
Anyways.. I've got 2 questions..
Recently.. my xenia fuge has been overtaken by calderpa I think grape calderpa.. I've reduced lighting intensity and time on considerably to help combat this algae...
I get a full screen of gha and bryopsis on my screen every week and I clean it off.. but the calderpa is showing nonsigns of slowing down...some has even taken root on my screen..
Any advice on how to combat this stuff?
I manually pull as much as I can every week When I clean the scrubber..
I have also reduced my feedings as well.. though my large fox face didn't like that and ate my fav acan and a Duncan..
Question 2... my scrubber algae is packed full of these little ant like pods.. and tiny shrimp.. I've tried shaking them off in the display.. and in my second tank as well... but they hold on too tight..
I don't like to kill anything besides aptasia in my tanks.. so now I have a 5 gallon bucket with a chunk of live rock...a bubbler.. and a crap ton of pod and shrimp packed algae....
How can I get the pods to let go... I though about setting a screen above my fuge or display.. and setting the algae on top.. in hopes that as it starts to dry.. they will abandon ship so to speak..and jump back into the water... Will that work?

Answer to both... stronger scrubbing.
The pods are eating your filter, so I'd scrape weekly in freshwater. Also maximize your lighting and bubbles, and add another scrubber if possible so you can alternate cleanings.
Caulerpa cannot beat strong gha growth because the caulerpa has no turbulent air/water interface to maximize nutrient transfer. The fact you have caulerpa growing, especially with pods, says the scrubbing is weak.
Scrape the growth and pods into your garden.

Over 10,000 posts in this thread! Dang, I totally wanted to be 10,000 and I missed my opportunity. I totally had it the other day too.
LOL. I want to thank you. You helped me so much.
