Most likely the best clean up crew is your self. Take a tooth brush and rubberband it to your siphon hose and gently scrub rock while you take water out for PWC
. Your clean up crew will help also. It is IMO
that unless it is a big crew they will need help. The main concern here is what is feeding this stuff. Are you overfeeding or high phosphates from tap or whatever ,it needs to be addressed. When I first had a tank 8 years ago I had hair algea and decided to feed every other day and get a UV
for the algea spores and haven`t seen it since. Almost forgot what it looks like.
