Is Marineland the brand name for it? I live in the UK and we don't have petco here. I got my fluval off ebay before. Do you think fluval is the reason why my vapour's going down too? I got the 510 a few days ago and the vapour was amazing, now it's declined somewhat.
I have been using the straw mod and that worked really well for a while but now my vapour's going down and i'm wasting loads of juice by having it stuck in the bottom of the cart. I'll have a look for the blue foam on ebay. What's the ZFM mod? I lurked on here a while back but haven't been on for a while, mainly cause I went back to analogues because I just got irritated with the DC901, now it seems that it wasn't so much the e cig itself but the way I was using it.

I use the cart caps to make mine, but Scottyballs sells them, and I think they are more consistent. You need a drinking straw, cart cap and an xacto knife. There pics and suggestions in the thread.
The idea is to make the cart into a juice reservoir with a heat-resistance silicone plug on top with a hole in its center. The drinking straw is cut so that it sits in the cart and its top is about 2 mm below the level of the rim. The the plug is put on top of it. So the straw acts as a shelve for the plug to sit on. The plug fits the cross-section area of the cart. The hole in its center sits right on the top of the bridge when the cart is in place. If made properly, the cart is filled with juice (syringe or slowly dripping it in through the hole), and then the cart is put on and vaped. It should
empty itself of juice entirely before needing a refill. And if it is made right it will, as in 50-60 hits before needing a refill.
I used this mod for months. The nice thing is the plug may discolor a bit, but it will not melt or degrade. One can use the cart for weeks on end without having to change filler, as there is no filler. ZFM doesn't die, change or need repacking essentially forever.
In the thread, Scottyballs gives a link to his new website where he sells the plugs. If you make them yourself, expect to get it wrong the first few times, thus going through caps. There are tricks to cutting the cart cap easily, and if it is wrong the cart will either leak or not give liquid. But once it is right, you are good to go, although sometimes the bridge of an atty might be in a slightly different position than in another atty that you made the ZFM for, which can mean leaking on one atty and great on another. It all takes time to get right.
To be honest, it is the best 510 cart mod I had found, and I tried many types of filler material. But now I'm using the aquarium foam, which wicks about as well and gives many hits before refilling, and is easier to make a cart out of. I still have all my ZFMs, and use them sometimes, but for making a cart that is almost as good very quickly with less problems if it is wrong, the foam is probably best.
