This tank came with my wife's grenade, and since I got her a PT3 too she didn't need it, so I adopted it. Unfortunately it came with a faulty coil causing it to leak like a mofo as soon as it was filled (some of the upper wick was missing), so I ordered a new one and tried to fix it by threading some new wick through the coil. I also added a couple of strands using a sewing needle to ensure it wouldn't leak.
I may have overdone the amount of threads I'd inserted, since although it didn't leak afterwards, it didn't produce much vapour either
The new coil wasn't really any better either, making me wander why these tanks are rated so highly. The draw is looser than the PT3 but doesn't produce the same vapour, and the flavour seemed a bit muted too. The only thing really going for it was the cool swivel drip-tip.
On Good Friday I accidentally dropped my PT3 glass tank which ended up in pieces, and had no spare at the start of a long weekend. This provided some incentive to get the 30b working properly, as the only other tank I have is a mPT2.
After seeing something similar on the 'net, I decided to replace the Silica wicks with cotton-wool (or 'car-din' as the Yanks like to say). This was done by rolling a bit I had separated into a thin enough sausage-shape to enable careful insertion through each coil, after the original wicks had been removed. I then trimmed the ends as close to the unit as possible, and squashed them inwards to ensure no leakage.
I didn't boil or do anything else to the cotton-wool before using it - as one user had stated, you get a bit of a funny taste at first, but it goes away fairly quickly. And you do have to be fairly careful inserting it - too much to fit and you can deform the coil, too little and it will leak. I luckily got it right.
The difference is noticeable from the first drag - vapour, flavour and TH all stronger. It may be better than the PT3 now, but I'll have to wait until I get another glass tank (and a spare!) for it before I can compare. It's working so well I haven't even missed the PT3
Obviously there are some drawbacks - the cotton-wool will not be as durable, and you can't dry-burn the coils without first removing it, but the improvement over the standard wicks was huge. And it wasn't too difficult to do either. I've run about 4 tanks through it since doing it and it's still working great, and I've only flushed it once when changing flavours.
Next time I will boil the cotton-wool first though - the 'funny taste' wasn't that great, and I've no idea what may have caused it
