I don’t deliberately fluff it in any of my tanks these days. I don’t think fluffing it improves anything in the low power realm. I may be wrong about this, mind.
Not a lot of details or photos... one person swears by 2mm coil and another by 3mm.Take a look at the wicking vid on the dwarv thread in the connoisseurs club
what works for me is: 2mm spaces coil, less cotton than you think it needs, put the collar on the deck and cut the cotton flush with the top then tuck it down to the liquid holes, so the wick is running perfectly straight right across. Don’t fan it or fluff it out at all. And you can have a little protruding out the holes, if it pleases you. Good luck with it, hope you get in better this time!
I don't know what cotton I use but it seems to be in pads and not at all fluffy, so I try to fluff it a little but it doesn't help much.I don’t deliberately fluff it in any of my tanks these days. I don’t think fluffing it improves anything in the low power realm. I may be wrong about this, mind.
