    Pics of GLA and Hong Kong diffusers at wok:

    55mm GLA diffuser(20psi-Concoa reg):

    60mm GLA diffuser(20psi-Concoa reg):

    HK diffuser(28psi-Victor reg). You can see this is not working properly:

    I believe the reason for getting only 0.3-0.4 bps is that the HK diffuser is not good(the last two pics). And, out of three HK diffusers this is the one that "works" best.

    What size tank is the GLA 60mm?
    Would like to get a back up 65mm for my 110g tank.

    Hi,

    55g standard. The 55mm is for the 30g breeder and the "HK" one is for the 10g.

    I have the HK one in my tank. When I switched to it I was really pissed because I couldn't get anything to come out of it. Then I switched all the tubing from airline to High Pressure CO2 tubing (the ada stuff but I'm sure it doesn't matter)... then bam.... millions of micro bubbles. I think it really needs to hit the 30psi before it will do anything. Only thing I would say... At least with my set up is it is hard to get small adjustments done.


    In retrospect I would have gotten the GLA one but I saw this at the store I was at and like everything else I had to have it now :)

    Now the HK diffuser works better and I get almost 1 bps, a big jump from 0.3 bps. Maybe the longer it works the better it gets. I can see a lot more mist coming out this morning. Btw, I did not touch anything in 3 days:confused:
    I am having my two Victors fixed by Orlando(RAOK) to be able to bump up the working pressure more than 28psi.

    Oh, forgot to mention that I also changed the tubbing and got the same results. Anyway, I am waiting for a new GLA diffuser.

    Also one thing to note which I did not know... cause the instructions were all in Chinesse. You need to presoak these for before operation. At least the HK one. So what you said makes sense.

    So basically the HK atomizer is as good as the GLA one but cheaper?

    I like the GLA ones better. Btw, out of 3 HK ones only one is working for me. The GLA ones are all working.

    Happy to say that things are improving on my 10g set up. I can go little over 1 bps and I think by tomorrow night it will work good. The diffuser needed one week to start working properly:confused:

    Thanks for the short review barbarossa, I'll buy one from GLA for my nano tank next month. I think this is a great way to introduce CO2 in a small tank :)

    I wanted to toss my 2 cents in here, since I also picked up 3 of the cheaper hong kong diffusers.
    I pre-soaked all of them for 24 hours, used high pressure tubing, and 35 psi working pressure. All three work GREAT. I'll try to add some pics later, but my 20 gallon looks like it's filled with smoke/fog. I've used both the boyu and Up aqua inline diffusers along with handfuls of different glass diffusers, including ADA. Nothing compares to these things. I'm a big fan of Orlando and GLA, but if you're on a tight budget I don't think buying the HK diffusers is a bad choice.

    Hi Indignation,

    Yeah, I guess they are good. I did not pre-soaked them and I can't go higher than 28 psi working pressure. My regulator is been rebuilt right now and I'll find out in a few days if I go to 35-40 psi the HK diffusers will work. I'll update as soon as I get the reg back.
    Oh, I do use high pressure tubbing.

    Btw, this regulator was sold to me on Ebay as "new" but, I found out that it is been used for several years and needs all the guts replaced. Lucky me, some nice guy is doing it for free. Lol, it looked new when I got it but, what do I know. If you guys want to know this Ebay guy name you can pm me. I don't want to paste his name all over the place b/c I am giving him the benefit of the doubt..........maybe he did not know it wasn't new.
