I completely tore down my
wet/dry and transformed it into a nice little
sump/ lighted
refugium. I utilize a filter sock to clean the water and alleviate micro bubbles but soon discovered that this needs to be cleaned at least every few days. I needed a cheap method to change out the socks but normally filter socks are about 5-7 dollars a piece. After searching around online I discovered a great website that I'd like to share with you called
www.filterbag.com . The bags are only $1.85 a piece. You have to buy ten but that means you always have some on standy or to give to fellow reefers. I got ten of these PONG100P3P filter bag
polypropylene felt, 100 micron, size 3, plastic ring. I hope
www.filterbag.com saves you a few dollars as it did me.
