Thanks, and hopefully. This system is over a year old at this point. I have been neglecting it some and I am sure this is part of the reason for the green algae. The algae is stiff and wiry, but usually slow growing. It grows up and not along the rock. I was thinking cladophora but I am leaning more toward some kind of turf algae now.
Honestly, it needs a good water change. : )
Yep, that red macro is so cool. I put it in forever ago and it has never been attached to that rock. Somehow spores just settled down on it and it has taken off.
