Hmm, I'll have to start trying the bleach thing. I'm never quite happy with how clean they get, even after running them through twice...Sirspifalot;4008271; said:I vote washing machine. I clean my filter sacks this way as well. I add a bit of bleach into though. Most people recommend a 15% bleach solution. I just wing it and dump some in and let em go. When its done I give it a sniff and if it has too strong of a bleach smell I put them in again with no bleach. Works great. I would imagine the same deal would work good with filter sacks or balls...which ever you wanted to wash.
yeah, there are some decent sized scratches on there.PeteLockwood;4008931; said:You probably don't want to be using Novus on that at first, you probably want a really high # grit sandpaper. There are threads on cleaning up acrylic tanks.
