Hello R2R'rs. Im a 5 month newbie in this hobby. Have a 75 gal rimless, with a collection of fish and Lps corals. Set up a 30 gal as my frag tank because i can't decide on a fish tank or a coral tank...So, now i got both. My question to all of u, is as far as your sump...What kind of bag filter are u using Felt or Mesh? Im currently using felt, but have bought 2 pairs of mesh to try. I like the idea that u can clean the mesh vs the felt. Also, what would i use to clean and how? i have read dishwasher, and the washer. Thanks for your input. Paul
