Ooooh, thanks for those! I watched the first one (even though I was having a spaz attack during her excruciating coil stuffing procedure) and it seems I'm doing it the same as her, EXCEPT I use rayon instead of cotton, and I use twice as much wick as she did. I didn't have time to watch the second video just now, but I'll come back later and see it.
I tried cutting my wicks a bit long the first few times, but because I had so much wick in there, there wasn't room to stuff the ends in, so what I did was juice them up and "fluff" them with pointy tweezers until there were no gaps. The other thing I do differently is I don't tickle the RBAs back into the tank. I just shove 'em in, so maybe I'm pulling the wick ends when it goes in or something, although mine are flush with the barrel, so they shouldn't pull, but who knows?
I guess the long and the short of it is I have a wicking disability.
I can wick ANY of my other tanks, even ones that most people say leak all the time, and get it perfect (no leaks), but these have just given me nothing but fits ever since I got them. But as I said before, I am stubborn, and I am (probably) insane, so I'll give it another go and see how it works. I'll try less wicking, but stuffng the ends in better, and I'll try to be more gentle when I'm putting them in the tank. The problem is I'm always in a hurry, and I do NOTHING slowly!
Thanks for your help! It is MOST appreciated!
