Red Slime or Hair Algae or ??????

[ensquire]

That is the lesson isn't it!!! Patience. Not one of my better qualities, but at this stage I'm not in to bad of shape. I haven't purchased any livestock or really anything for this tank yet. Just feeling my way through it a stage at a time. Amazing how much good material there is here to use for reference/ inspiration.
Rock will get cleaned and stored in large rubbermaid bin with heater and powerhead. Would it be a good idea to store sand in a similar fashion??
Also, for gobies and wrasses, what is the best type of substrate??
As far as reactors refugiums etc, My stand is pretty much out of room.
