I had problems for awhile until I started stretching out the cheato a bit once a week. Just enough so the water flow can get through better.
I'm battling this similar issue with my attempt at a fuge. I switched out the first and second chamber in my trigger sump and I just bought a Kessil H80 light this week. Unfortunately all I have is a small clump of caulerpa and this one weird algae that is viney and looks like gummy worms when you pull it out. No clue what it was but the LFS had it mixed in with the rest of the macros.
I'm going to try and buy another seeding of chaeto to see if I can get it to take off with the rest of the macros and not melt away. I'm currently battling a small cyano issue and hair algae is growing in my refugium so I know I have nutrients....
Here's a pic of my current fuge setup.
Is there any flow in your system? It looks stagnant.
There is flow, a mag 5 for the 93g cube so about 3 - 4x turnover if I remember correctly. But due to the way I changed around the chambers I'm the trigger sump there is nothing to break up the surface tension in the first section. Could that be part of my problem?
Wondering if I should switch it back to the second chamber as it was designed
What is your head height for the Mag 5? If it's any considerable distance (>4 feet), you are likely getting less than 500 gph from it. For example, at 5 feet head height, a Mag 5 will push 325 gph.
It's about 4ft, plus or minus a few inches. But that's still 3.5x turnover?
Yes, but you will want more flow through your refugium. Do you have a pump in there or something providing more flow through it? I have a 90 gph pump in my refugium to help spin my macro. It tends to get slimy with only the return pump flow through it.
I just started a cheato reactor as well. It has been amazing! Here is the thing. I had a large amount in there to drop the phosphates down to zero. Now that it is where I need it to be. I ripped 3/4 of it out to maintain a balance. The cheato stays alive, because there is a small amount of cheato. Now, every week I rinse it off with new saltwater and I make sure it does not have anymore than I need.
If your running other filters like a skimmer maybe you could turn it off? Or maybe you could add more livestock?
I ultimately added another fish and really upped my feeding. Seems like I’m finding a decent balance.
That was not my experience. I found no statistical benefit to iodine supplementation to growing chaeto or caulerpa.

Iron, on the other hand, can make an immediate effect (visually, even) on macroalgae if it is deficient. The owner of a big reef board found his macroalgae greened up a lot after dosing iron for the first time.
Just reduce your refugium photoperiod or intensity to find a balance. You and your livestock are constantly adding nutrients to the system, so you can't use them all up. The supplements are to make the algae grow faster, not to keep it growing if it doesn't have enough nutrients coming in.
