UPDATE:
So far it has been staying on now with all the help from many. The bubbles are still a bit larger than i would like but i guess i was expecting super fine mist. Perhaps itll get that way with the next cleaning. Will test it for the next few months and reupdate.
- Working great! Still wish it was easier to get the tubing on but its working well!

Original Post and First Impression:

Just tried out my ADA diffuser I got. Honestly, very unimpressed. Look, it works great, but its not like a super fine mist of bubbles as i have seen on some ADA diffusers. The bubbles are fine but not like this: https://www.youtube.com/watch?v=Y4o42N5cBGc. I can't tell if in the video the bubbles are actually smaller, but it sure seems like it.

Here's some issues i have with it:

1. In a small tank, has a big footprint. The fact that the tube can now be routed directly down instead of underneath (POLLEN GLASS TYPE-1 O_O) is a huge plus, but the glass knob that a suction cup attaches to makes the diffuser stick out quite a bit. Larger tanks, this is fine, but i have a 10 gallon...

2. Speaking of the tubing, its a nightmare getting the CO2 tubing to fit onto the glass inlet cylinder on the diffuser. First of all, its as if they designed it to work only with the silicone tubing they manufacture. I have some luckily, but i dont use it anymore with my new CO2 system. Anyways, Its not the easiest thing to get on with either tube (it does not have a conical tip like other diffusers) and even if you get it on, it goes about 1/6 of the way down before you tell yourself, "Oh oops.., don't want to break a $75 piece of glass". So I'm sure it can go down further, but i am not about to risk it.

3. With my other NON ADA tubing (not silicone), this fucker just popped off in about 45 minutes. So, unless you get it down farther, its gonna pop off. And as in #2, its a SOB to attach.

4. Price, then again, only ADA product I happily offer my money to is Aquasoil...then again....-_-

I have since today gone back to my original diffuser, this cheapo one I bought from Amazon (some dealer iono). Comparing the bubble size to the ADA, the bubbles are approx the same actually, at least when its not clogged. Also my diffuser has a conical tip and some sort of groove that allows it to attach to the tubing more securely. Also ran me like $15.

Overall, I don't want to shit on ADA since I dig the aesthetics of their products, and the diffuser assuming it didn't pop off, works 100% albeit better than other vendors. However, with respect to my current diffuser, i will sadly have to put this thing into storage for later use. If someone who has similar or same product can provide clarification on installation, or anything else, I would love to give this another try.

Mineral oil on the tubing.
Over time and cleanings, the ADA should do better.
I use Tygon tubing, this has been the best stuff for me over the years, thick and still flexible.
You can also heat the tubing and it'll make it much easier/safer to get on/off.

The finer the bubbles, the higher the backpressure.
I went the other way and used needle wheels/reactor tubes and sumps etc.

Thanks Tom, I will give this a shot once my current disk gets clogged. I hope to report with positive results.

Update:
Tom i tried the mineral oil. Doesn't really work for me since my hands get slippery. Its still hard enough to get the tubing on. BTW i use tygon R3603 tubing. Anyways, past 3 days ive had my diffusers pop off for some reason. Even my older one. So finally I argued since its happening to both now, its not the ADA's fault. So tommorrow i am giving the ADA 1 more try. I spent 5 minutes today just doing everything i could to slowly slide the tubing onto the diffuser. It is ridiculous how hard it is to even get on. I even had tested the tightness yesterday and it was hard to pull off.

Anyways, this time i have the tubing down almost 2x the amount i had ever done before. I can't believe it actually went down that far given how hard it was. I used a paper towel to increase the friction between my finger and the tubing. This allowed for more control. Honestly, I wonder how i can even get this off now but, this had better be enough. If not, i am going to go inline needle wheel. Love the look of the diffusers though.

Put the tubing in the micro wave for as few seconds wet.
Or in a bowl of very hot water.

OK did that and its on about 3/4 inch on the diffuser. Hot water really helped and my fear of breaking it is less. Took a photo to document this shit. Lets see if its still on in the morning. Time to zzz.

Safety:

Hot water works, but any time you remove or add tubing to glassware, use a shop towel or gloves etc to prevent cutting your hands if the glass breaks.

Tom, is it possible to clean the diffuser without removing it from the tubing? I usually soak in bleach then 2x declor soaks. Also good news, has not moved in a day. I know big achievement right?

Michael ~ when doing your weekly water change or maintenance raise your diffuser above the water line. Fill the diffuser/ceramic disk area with h2o2 or excel and let it sit while you work. Once you are finished lower it back down. It will not be 100% clean at this point, but it will in a few hours. If you need to remove it and soak in bleach, use a razor blade and cut off the tubing. Pulling the tubing off after it was so hard to put on will end bad. Hope this helps.

Antbug is 100% correct, the h2o2 is magic, I do it once a month

I use to simply pull the diffuser out and set the whole thing still attached and running with CO2, in a cup and then added/sprayed good with Tilex.
Wait 10-15 min, then rinse 3-5x real good, then soak for 10 min in dechlorinator and water, no smell? Then I return it back to action.

I dip the glass tube on the diffuser in tank water, then work the silicone tubing while gripping it with a paper towel. Works everytime.
Before using the ADA diffuser for the first time, soak it in bleach for 15 minutes. Then shake out the bleach from inside the unit, rinse with water, and inject prime in the unit. Swish the prime inside the unit, then shake it out (let gravity do the work). Then rinse again. Try not to touch the ceramic disk (this can damage the surface).

The ADA diffusers are about the best you can get when it comes to ceramic disk - style diffusers. They are more durable than the high pressure atomic-style diffusers, imo. No problem providing a 55 Long (48"x13") or smaller with enough CO2.

Yea Matt i think i read your post somewhere before. It helped but it still didn't get it far enough down. The hot water + paper towel + No fear of breaking it anymore has proven the most effective.

That's why I wiggle the whole diffuser inside of the silicone tube to work it on the stem. I'm able to get the silicone tube on the stem > 1" this way w/o breaking the unit. I've found other ways to break diffusers! LoL

Keeping the unit attached to the tubing and spraying H2O2, or glutaraldehyde on the disk seems to work as well. Let it sit for a while, then plop it back down into the tank. This reduced the risk of breakage.
