i've been getting tired of my chaeto running my refugium, so i decided to make a cage for it. Real simple, all i used was some gutter guard and zip ties.
first i found out the size of the cage i needed, due to refugium size.
top view, again, simple, just a simple cage that will house my chaeto or live rock for that matter.
do a test fit to make sure it all fits snug
add your chaeto
insert cage into refug
