Mucus Algae Identification

[Y-Diver]

I have had this slimy clear mucus like algae start growing in my tank in the last week. In texture, is very similar to coral mucus in that it is stringy and slimy and clear however it is not coming from coral. I have mostly sps in the tank and they are all still doing very well with great polyp extension. The skimmer has been skimming much more lately and the mucus is making the water cloudy. I run carbon and GFO from midnight to noon each day. Water changes are made twice weekly. Tank parameters are as follows:

29 Gallon BC
Set up since January
Rock has been in system for 4 years or so
Temp - 77.5 - 78
Cal - 440
Mg - 1350
Alk - 8.6
Nitrates - 0
Phosphates - 0

Here are some pictures. Any help would be greatly appreciated.

Thanks,

It's netting from vermite snails, harmless till they get out of control then it's a disturbing sight in the tank for me.
