What else can I do?

So the short version of this story is that I had a bad cyano or some type of algae problem. It looked brown and snotty with bubbles. The bulbs I was using were over a year old.

So what I've done so far to try and get my tank looking top notch again is I've changed all 6 bulbs on my t5 fixture. I've added cheato. I did a round of chemiclean about 4 days ago. Took all the rocks out, rinsed them in some fresh salt water and scrubbed them. Did the 20% water change and have my skimmer running again with carbon and gfo.

I've also added some sand back into my tank since I was running it bare bottom and added a conch and another snail (like a huge nassarius snail).

Here are some pics of the algae coming back a bit again.

Duncan which has been closed for about two days starting to open again. You can see a big string of the algae.
