For my 160 Gallon Tank

The tank has been running for a couple months now cycled quick and water parameters are good. Anyways I have always noticed the filter sock overflow with water and are clogged quickly. Thought that was just the tank settling and kept up on my changes. However yesterday I did my weekly maintenance which included a ten percent water change, filter socks changed, sponged rinsed out, and I cleaned out my skimmer. While changing out my socks and cleaning my sponge I noticed they were coated in a clear gelatinous slim. The sponge took forever to rinse out.Today I look at my tank and its cloudy. Not sure if they are correlated in anyway because I added a couple pieces of LR and stirred up the sand bed a bit during water change.

The main thing that worries me is the slime because the socks are already overflowing again today, no doubt from the mysterious gelatinous slime.

What could this be? It has been a few days since my last water test but everything should still be on par.

Extra info that probably may not matter........... recently had a diatom bloom I'm guessing will go away as the tank ages, This is my first fuge also within the last couple weeks my refugium has gotten quite dirty, so I added a few CUC members in there.
