Help!! A couple of newb questions...

I have cyanocobalamin in my refugium too. I am not worried about it I would rather have it there than in my display.
My fuge is lit for 18 hours.

The brown algae in display looks like it is from your tank being new. But I am guessing your flow is not the low side. I don't see any sand dunes from being blown around.
I did see something I am questioning. I see 3 empty snail shells. What does your cleanup crew consist of?
I like to use several different types of snails and crabs and other good cleaning fish and inverts.
Maybe something to stir your sand. Like a fighting conch and some nassarius snails.
Looks like a dead spot from low flow where the algae is at.

 

Sounds like a good crew. That starfish probably won't last long. Tank isnt mature enough yet. I tried one in my 5 year old tank and he only lived about a year.

I would say with some more flow your spot of algae should clear up. But like you said no matter what there is always dead spots.

I like my flow to look chaotic. I have 4 mp40 on a 120. I have spots were there is no sand and spots where there is 3 inches. I still get spots of red cyano in my sand. I just got a diamond spot goby to stir my sand. I also have 4 fighting chonchs and 20 nassarius snails to turn it over.

You can siphon it out on your next water change but it will probably come back.

 

Ive heard of red slime in the sump/ref, people usually add a powerhead to get a little more flow.

 

Just keep up with regular maintenance siphon out when doing a water change and sometimes you just have to let it run its course. I also had it growing in my refugelium to i wouldn't worry about it.

A diamond goby might stir the sand a little better than the star fish..... But don't know what size tank you have and what type of light do you have on the refuge

 

more flow and some stomatellas would do some good. What's the parameters btw? Apologies if I missed it

 

Ahh the joys of being a new reefer.
We've all been here!
"In my opinion"
It's truly a flow issue & just the sand bed being new/newer.
I battled it for yrs.
until one day I sprung for the mp-40 in my 72 gallon tank.
It truly makes a world of difference.
Oh and one of these guys helps too.
Fighting conch $8
Just my 2 cents
Good luck
