| I actually bought about 3 cu-ft of scrubber pads. They look different than theirs..and are similar in texture to J-Mat. I have used nylon scrubber pads in the past..I will try these new ones which are more dense. My question is...what is that sand? Are they correct...or did some dirt end up in the filter? I am definitely curious.
In the saltwater reef hobby..we intentionally have a 2-3inch sandbed to grow anaerobic bacteria. This acts to remove nitrates. Would this simply harbor aeromonas and pseudomonas in our pond applications? |
