Just tell them to refund your money or call your credit card company to initiate a chargeback.
No attorney is going to take this case-it has no standing for a class action suit.
No law enforcement agency is going to do anything either. At the most they will take a report, then complain to each...
It's probably a diatom bloom. Mine consisted of small reddish-brown round cells that formed along the base of the rock. They could be blow away with a baster. Since their skeletons are made of silica; remove the silicate and they will go away. I think most tanks will go thru this at some time.
My female Maroon clown does the same thing and it has an anemone. I think it's some kind of housekeeping behavior. There was never any food involved in this. I would have said it was associated with preparation for spawning, even though no male is present, but when the anemone moved away from...
It's probably not a he. The females are a brownish grey color.
Here's an article to look at, scroll down to see pic of a pair:

Agreed, there are many restrictions on the suction side of the pump and likely won't affect the pump performance. It is a general rule/practice not to restrict the pump suction. Centrifugal pumps can cavitate if the suction is throttled. Not a real problem with these pumps. In any case...
I agree. Don't restrict drain flow with either a valve or by making the lines smaller. Place the ball vallve on the return line. You could also get a smaller pump. You didn't say what you were using.
Make sure the air intake is open. Also make sure the discharge pipe isn't under water. If it's installed in a sump the water level should be even with the bottom of the discharge port.
Start with outlet valve open all the way. You should see bubbles inside the tower. Slowly close the outlet...
The specs on your camera list focus distances as:
Normal Focus Range: 50 cm(19.7 in) to Infinity
Macro Focus Range: 4 cm(1.6 in) 1.6 - infinity
This means in normal mode that you can't focus on anything closer than 19.7 in.
In the macro mode it's 1.6 in but if I'm not mistaken that's at 1:1...
You may want to consider putting your refugium on the end with a branch line off your overflow. You can limit the flow to the refugium this way. Otherwise it has full flow from your tank going thru it.
IMO the ball valve on a recirculation line off the return back to the refugium, "to control...
