Looks more like sponge.
Is it hard to scrape off? It looks like green coralline to me. Purple is the most common, but it comes in a bunch of colors.
You say "worse with water changes". Do you dose calcium? This implies its growth is limited by a lack of calcium, your water changes supply a fresh dose.

I don't think he's talking about the green coraline, the white stuff in the photos is what he's asking about I think.

Agreed, but I'm going with sponge. As you can see, it's even at the far end of the picture. Don't think there will be that many dead organic matter unless something went horribly wrong.

Hmm why do you say so? I'm not denying, I too want to learn. But for now, I'm guessing water change are causing those bubbles to be trapped.
Anyways, have you tried pressing them? If it feels "crunchy" like one of those green floral foam then I'm almost certain it's some kind of sponge. It does look crunchy haha.

Hey flamron - that is definitely a kind of cyanobacteria. Certain taxa form mats like that and the bubbles are the product of photosynthesis that just get stuck in the filaments!

...if the tufts are really tough, it may be a Schizothrix sp.
You don't think it could be dinos? It one or the other... def. not a sponge.

Are dinos dinoflagellates? (excuse my lack of forum terminology 
) If so, then no - dinoflagellates don't grow in clumps like this. If you mean diatoms, then I also think not - a diatom bloom looks like a brown film-like mat with bubbles in it.
To my knowledge, only cyanos have growth forms like this. Totally agree that this is definitely not a sponge!
