I have a 10 gallon sump so my refugium section is not that big. I didn't know how big to let my chaeto grow. I noticed that it has grown so fast that its almost to the sand bed in about 2 months. Does the sand bed need some light thru the Chaeto to have the right nutrients for our little bugs to survive. I can take a picture later to help.
