Every time I DIY CO2... This....

I guess I'll start here. I've had this problem in the past... And his is my first attempt at a planted tank... But...

I recently moved, it wasn't a very far move, but disturbed my substrate (Eco complete) enough to be detrimental to my community of five RCS and a single glowlight tetra... At least that's what I have narrowed it down to. So since I now have a planted snail tank... I've decided to start dosing DIY CO2 again to promote growth of DHG.... However, the very same results I encountered the first time around adding CO2 have repeated themselves.... I can not find a valid explanation anywhere...

Here is what is happening....

Immediately (half hour to an hour) upon diffusing co2 my air pump weakens... Very weak. But somehow gets stronger the closer you bring it to the surface.... The tank develops a ghostly white slime on the surface of the water, and surface tension becomes so high bubbles will not disperse (even co2 bubbles). Among those two problems which I have only narrowed down to low PH (which is good in a planted RCS Setup with my hard water conditions).... is what I am referring to as miniature dust particles... Which are exponentially worse daily. To the point I can actually take pictures of it.

I am using a two liter bottle, two cups of sugar, 1/2 teaspoon of yeast and baking soda

These problems are confusing the hell out of me and I would like a little insight from someone WHO HAS BEEN THERE, or would know why I am in this position.

My water parameters are always great (aside from the cycle my mixed up eco complete created) to the point I don't often check them...

I waited for my parameters to be right back to normal, then resumed DIY CO2.... Before resuming my tank was absolutely prestine, the water was so clear you couldn't tell it was even there from the front....

I use a 20gal HOB with ceramic cylinders (fluval chi), polyester filter floss, seachem cuprisorb, and seachem purigen.

I'm not sure because they are so absolutely tiny that this dust is micro bubbles... It doesn't seem to float, and goes with the flow of water (and through the intake filter)

Does anyone have any idea what might be going on? The cycle is over.. Everything was great again... I use a CO2 separator, this only happens when I use CO2 (I would like to continue to in a proper manner). Again my main concerns:
1. Surface Tension (air and CO2 bubbles accumulate)
2. Dusty water exponentially worse daily
3. Slight slimy white residue on surface
4. Protein???

Bump: Also I do (normally) weekly water changes on Sunday's.

Are you using a check valve with your CO2?

Are you using a second bottle with plain water in hookah configuration (large bubble counter) to keep yeast out of the tank?

Two cups of sugar seems excessive for a two liter bottle. The yeast will probably die from alcohol poisoning before it uses up the sugar. I found one cup of sugar lasted as long as two in a gallon yeast bottle.

Forget the baking soda. It doesn't help.

What are you doing with an air pump while dosing CO2?

If you have a choice, you have a problem, till you elect your choice. No choice, no problem, only consequences, learn to live with them.

I was thinking he meant "air stone" instead of "air pump".

Something is very wrong if he really meant that he is bringing an air pump closer to the surface.

@Argus

Instead of supposing let the thread starter clarify.

I've seen this before w DIY co2. It's like a clear jelly almost like saliva or something. It always went away on its own eventually. No idea what causes it.
