hcigar Aqua clone at .4 ohms with dual 26ga twisted on 5/64" drill bit with cotton. Did it just like my kayfun which put out pretty decently with only 1 coil.

Why so little vapor production? Help!

Post pics, lets see what the build looks like

couple of things come to mind. for one I have heard of airflow issues with the clone, like obstructions. do you think this is the case? also connection issues, I have an aqua and it seems like if I don't tighten the connections really well, the coils just don't seem to glow to capacity. another issue can be flooding, the aqua wicks extremely well, even better then the kayfuns and if juice control is too open or somehow your getting flooding issues then the vapor production will be low. I used to fill from top but kept getting flooding issues and gurgling, once I got used to filling from bottom, all that went away. good luck

It DEFINITELY feels like an airflow issue. Thought about getting the drill out but was nervous to do so... Pictures to come soon.

that would definitely do it, especially dual coils at low res. as i remember the one who had the same issue also tried to drill out the holes but failed, he is now using it as a paper weight. i do however think there is a way to take apart the bottom section and actually see the path of flow, but not sure on the clone model.

I was having similar problems with my Aqua. Dual coils work or me with a resistance of 1.2-1.5. It seems that low resistances don't play well with the Aqua or even my Kayfun. Getting the right amount of wick will also make a big difference (using cotton). With four channels that are bigger, more wick will help with flooding. Keep trying different setups, once you get it right it will be worth it.

the aqua is really built for low resistance and actually does an awesome job at it. imo this atty shines at resistances below .6Ω, but like everything else the device needs to be in perfect working order and the build also.

OK y'all... Pictures as requested...

Sort of hard to capture the vapor. Also, I did quickly wash and dry the base + chimney after removing the tank for obvious reasons.

Dumb question, Divr... How do you bottom fill this?

Ok, I definitely think its an airflow issue. I re-wicked and saturated and fired the coils. A light gust and it's producing MASSIVE vapor. It filled the room in only a few seconds blowing on it. Then I put the chimney on and tried to pull through it. Nearly no vapor - certainly by comparison. Any ideas?

Looks like it needs to be dry burned and re-wicked, perhaps with a little less cotton. Also, the one coil looks like it might not be positioned right over the air hole.

Make sure it isn't flooded. Mine tends to flood just a bit when filling it no matter how careful I am. Vapor production is a little off until it's cleared. Take a few drags on it with it upside down to clear the flood and it's good as new.

Will try this tonight!

a few ideas for you buddy, one I also think your using a bit to much cotton, also I don't like the position of the airholes on the clone, they really should be centered between coils, the way it looks now seems like one coil may receive more air then the other, but unfortunately there is nothing you can do about that. have you tried doing your coils touching? in the pics it looks like they are spaced. also how much gap do you have under your coil? it looks from the pics like its quite high but its really hard to tell. I find about 1.5mm to be perfect, usually the higher the coil the less vapor but to low isn't good either. you asked how to bottom fill, well if you want you can see in this video. aqua tank dual coil build - YouTube. about the airflow issue, I have heard of this before about the aqua clone and not sure what can be done but I do remember a pic posted where I believe the guy unscrewed the positive post which somehow opened up the very very bottom of device, somehow the plastic part around the positive post base came off. once off you could see the air path around the base of device. also a good dry burn and new wick would probably help a little

Vapdivrr you have some excellent suggestions! I dry burned and replaced with drastically less wick than I would have imagined. Vapor definitely increased. As far as the coils being spread, I think I need to move to a lower ID or something because the coils were small to begin with and they may have become spaced upon installation. First build on first knurled but device, u know.

I played around with deck spacing, but vapor production only increased a small amount. Honestly, I was a little shocked when I switched to a 70/30 pg/VG from my normal 70/30 VG/PG blend (bought juice instead of making it). The vapor production went waaay up.


I'll report back after I do a few more builds with your suggestions, diver. I definitely appreciate your help!

i know what you mean about the spacing. i think it happens when we tighten up the nuts, sometimes this pulls apart the coils so keeping in the bit or whatever you use inside the coils as you mount definitely helps. and no doubt that vapor production will drop by less vg in your juice. not an easy set up for sure, patients and time will help in finding a good set up. good luck

Watched the video, excellent advice. Oddly, I've actually watched quite a few of your videos vapdivrr! I didn't realize I was speaking with YouTube royalty!

I've gotten some better vapor production after playing with the wicking and airflow. I'll probably rebuild the coils tonight and see if that doesn't fix the problem. Out of curiosity has anyone tried a cotton cloud or tinman in the Aqua yet?

On another note, I'm a big dive fan too. Used to do some tech diving but sadly moved to Kansas since those days.

I gotta say, I am disappointed in the Aqua. So far the only way I could really build it to suit my tastes is with dual chimney micro coils around an 18 Ga needle. For the ground post, loosen the entire neg post at the deck (not the knurled top part of it) and ground the neg coils between the deck and the post. I use a tiny wick and place it in an X across the middle of the deck, and wrap the wick around the outside of each coil into the opposite juice channel. Make the wick about 1/2 the diameter of the coil height so you can wrap both legs around the coil (one low and one high).

It clouds like a freight train.

I'll try to take a pic a bit later today. I want to empty the juice I have in it now first, though.
