There is so much sh1t going on in my tank right now! Algea out the wazoo, copepods, bristleworms, etc. I have these white worm like creatures who are building little tunnels, and these white bugs that are much larger than copepods that are walking around. I'll up some photos later.
I would suggest taking the nozzle off of you koralia and putting some flow on your sand bed to try and keep it clean. Are you planning on adding any more powerheads soon?
