Sounds like Cyanobacteria. I have heard you get it when co2 levels are too low. I used peroxide to get rid of mine then went with diy co2 and never got it again.

It looks like it but it's not making that scummy layer that cyanobacteria has

I looked it up. I think it's green dust algae

Do you have any pics? Cyano tends to show up when nitrates hit 0 or appear in areas where there is low flow(dead spots) and nutrients aren't being distributed sufficiently. I'd say clean out as much as you can by hand VERY carefully and add extra nitrate. I had it once. I picked out what I could with my fingers, re positioned the powerhead to add extra flow to that area and doubled my kno3 dosage and it never came back. I got very lucky.

I'll try to get pics up soon

I had a problem with cyanobacteria on a few occasions. I ended up completely covering the tank for 3 days or so and was all gone when I uncovered it. I also added a powehead for circulation which seems to have helps as i haven't seen any since.

The other picture wouldn't load.

It's hard to see in this but it's on the leaves

What was different for your tank while you were gone?

 

[Raymond S.]

Other than possibly overfeeding, like jerman83 asked, what was diffeent while you were gone ? Do you have your light on a time ? Can/will you describe the light(s) more fully ?
From the way you list it, I can't tell if it's one or two fixtures for sure.
That is a good enough filter for that amount of fish. Plenty of breeders just use those only. This link gives some good info on your issue.
You have a problem which will almost take care of it's self but you may need to up-grade
your tank care to help from it coming back. The link describes the use of ferts for it
and I think that the PPS system woud be best for your tank but the EI is also good.

I never heard of an algae bloom killing fish. Did something else happen while you were gone?

 

[jrman83]

Did you by chance leave the light on the entire time? This could explain more algae and possibly some plants melting.

Thanks!
I think the only thing that could of changed is the feeding.
The light is on a timer so it wasn't that.
I don't really know much about the light exept that it's a fluval LED and my lfs sold it to me for dirt cheap (1 fixture).

Update: Did a 3 day blackout.
This is killed off almost all the algae.

BUT!

The algae came back seeking revenge. It. Is. Awful.
