how thick does your algae get in the refugium and does it start to transform?

the algae in my refugium is starting to take on many different forms. I changed the light from purple to white due to it visually appearing the algae was turning black or being burned by the light. instead under white light there are many different algae taking place in the refugium. one of which is a very dark green leafy algae that sits at the top. red algae and what appears to be in some parts dragons breath
 
I switched to a cryptic refugium after changing tanks but previously I pretty much had no other algae than the purposefully grown Caulerpa prolifera in my sump. I used the Tunze eco chic refugium 8831.

cool light,...... I purposely put the hair algae rock in my refugium. I bought it as live rock and wanted something full of algae when I jump started my system. seems to be working out fine. just was curious of the many forms that have grown.
 
I also have switched to cryptic refugiums. And grow ornamental seaweeds in display tank.

Yes to growing seaweed under white light. White light allows me to observe & evaluate seaweed growth. While it’s true that red light may be a more efficient use of electricity for growing macro algae, as a mariculture facility, white light allows for growth bioindicators to be observed in real time.

Sponges & red macro algae were just received from GCE.

I ran an original Dr. Walter Adey dump tray design for a few years. It took up a ton of space. It grew hair and slime mostly and sometimes a bit of weird turf. This got thick, but at some point was so thick that it would lose flow.

I retired the dump tray for waterfall types, but never liked dealing with their maintenance. The algae got very thick on the waterfall scrubber.

I then ran a 30 gallon refugium for several years, but found it to be a detritus and aiptasia trap that also took more maintenance than I wanted.

I don't run any type of scrubber or refugium now, and haven't had an algae problem for years until last week when I responded to Paul's thread and Randy's thread. Now I am pulling GHA out of the overflow guard every other day. Their fault, nothing I did.

My sump is mostly dark, full of rock and inches of mulm. If we want to count that as a cryptic refugium, then so be it. Some sponges, billions of tube worms and spirbid and spionid,. etc. Even discos that are translucent (rocks from tank moved to the sump) that have lived with no light for years now.

I'm awaiting your peer reviewed paper soon
