If its not dinos then in it may be Calothrix. I've been reading a lot on this stuff. Tank is blacked out. So is refugium too. Wrapped in a thick blanket to starve this stuff. I bet my fish hate me right now.
 
You need to be careful keeping the lights off in your refugium. Your algae can "go sexual" depending on what type you've got and it would poison the tank. What type of algae do you have in the refugium?

Also, why would you need that to be off? I'd keep it on, for sure. It will help stablize your probably plummetting pH.

People strive to keep "perfect" aquarium conditions, to mimic nature....but the reality is that in nature, we often have a day or two of cloudy weather and storms. Also....in intercoastal areas, corals survive for hours without being underwater...but nobody tries to simulate this either. :)
 
I just try to keep my calcium, alk, magnesium in balance and water change like mad (with good RO/DI water) to keep my nutrients down as much as possible. I'm seriously a minimalist when it comes to messing around with my tank. I can't even believe I got a phosphate reactor, though I am super loving it. Next I'm going to get LED actinics...seriously stepping into the 21st century for me.

Spencer: are you coming to the meeting Saturday? I can give you that frag when you do! Or I can send it with Jake in the morning. Let me know!
 
Lights off for 2 days KILLED THE EVIL BROWN CRUD my tank looks beautiful again. I siphon the crud off , which just fell off the rock, which extremely easy to do compared to the situation it was in earlier. Plus I now feed every other day. I like my tank so much more now that I got me a new fish.
 
This actually doesn't surprise me in the least, sorry man. I think you might consider focusing on water changing with really good RO / salt for a while...doing weekly 25-30% water changes for a month maybe?
 
Water changes are said to help dinos accourding to different threads I've read in past. Not sure why.

I guess water changes with RO/DI water that you know is REALLY clean and a good salt mix is basically my default for any issues I'm having BUT...don't you think it makes a little sense? If you starve the algae for nutrients (e.g. get your nitrates and phosphates down way below detection) then those algae should have more trouble taking root.

Then there's the other side of the issue in that since the corals have algae in them, they'd need some nutrients as well...so that complicates the argument. BUT I do know that for whatever reason, when you make your water really clean, nuisance algaes have a much harder time growing than corals do. Well, depending on the coral. I mean, some corals love dirty water...EvilMel's green skirts zoanthids for example.

Also, it seems that the photosynthetic algae in corals are more easily able to capture nutrients than the nuisance algaes.

I honestly think that your issue could be that dry base rock you used. Everyone I've ever heard about using it has continued to have algae issues.

Maybe you should slowly replace it with good live rock?
 
If you are referring to the rock I mentioned before that stuff is in my dads tank. My rock came from aquatic marine. And some of it came from a former club member who got out. All rock was algae free. I'm going to start h202 Dosing.
 
OOoh! That's good to know. I've been operating under the ASSumption that you had started with dry rock. Cool, cool.

Water changes then...lots of them. But not lots at once...slow, steady 25-30%
 
Yup I agree Mel on the water changes. But I think dinos are different. I duno I'm just goin off what I recall reading hehe. Either way I hope whatever you do works. Kalkwasser was said to help as I recall as well. But you needa dose enough to raise ph a little.
