Been out of the hobby for many years after owning a Saltwater only fish store back in the early 90's. I got the bug again when I found an adult Hawaiian Dragon that needed a new home. Poor thing was in a 110 gal mixed reef tank. I dusted off my 500 gal tank that I kept from my store about 6 weeks ago. The technology has changed quite a bit. I've already bought an Apex and 2 Clarisea SX-5000. Love love love the roller filters. So I went through the 2 rolls relatively quick and my LFS was out of replacements. I went online to see if anyone was cleaning the fleece material and much to my surprise NOTHING. I then took the dirty (very dirty) roll spun it off the motor stuffed it in a linen bag and threw it in a front loading washing machine (speed wash, extra spin and rinse) with a half cup of bleach. Before running the cycle I did a rinse cycle to remove soap residue. The roll came out white as snow. I then soaked it in a bucket of RO water with a bunch of Prime then rinse only and spin again. Then sun dried the fleece. Rolled it back on a roll and it's working like a champ. I'll have to figure out how many washes the fleece can handle. I'm just putting it out there to see if anyone else has tried this. If so let me know your experiences. Hoping to get 4 or 5 washes. Nice cost savings.
