You have several different algae in there. The general diagnosis is always the same...reduce nutrients. Depending on exact types of algae there are some tricks to help out.

What test kit are you using to determine nitrate and phosphate? When you moved the tank did you reuse the sand or did you install a new sand bed?

Looks like diatoms. Have you checked your RO/DI filter lately?

Thank you all so much for your replies and suggestions. I really, really appreciate it!!

Well basically, I've decided to try starting out with the basics. Obviously, my biggest worry is dino algae - and since I'm unwilling to even think that's what it is, and since there isn't really a proven or easy treatment for dino - I've decided to basically proceed as though its everything but. Haha. Essentially, im going to follow through with all the advice I was given.

I went into my garage and hauled out a bunch of my 'i'll keep it just in case' stuff, and heres what ive gotten up to tonight

- I found an old reactor and put some gfo in it. Im running it in my sump now
- I did a 40% water change sucking out as much 'fur' as I could along the way
- I changed my ro/di filter
- I took out and scrubbed all plastic or removable items that were covered ie pumps, powerheads, ect
- Drained both overflows and rinsed all if the sediment out of them
- Set up a UV sterilizer that I acquired somewhere along the way
- I moved the corals into a smaller tank so that I can keep light on them, but off in my main tank.

So that, in a nut shell is where I'm at. I'll update my thread over the next few days. Hopefully I see a change, because if I do, its probably not dealing with DINOFLAGELLATES. Fingers crossed ;)

Ugh. Time for bed.

Thanks again

There are worse things than Dinos... :D

Sounds like you have a good plan in place as long as the corals are happy in their temporary home.
