The bubbles have slowly started to increase over the past month. Am I supposed to lube a certain part to solve this issue? Also, is the product I attached good to use?

No, you shouldn't need to lube anything in a canister filter. Sometimes you can lube the seals if they're being pushed out of place when you close it up, but that's rare. Or if there's just a connection that's too stiff. I've used petroleum jelly for that in the past, it's pretty non-toxic. I wouldn't use what is in your picture.
thanks where are the seals? Are we talking about the two hose connections which clamp to the canister filter?
I'm talking about every rubber gasket or oring when I say seals. There are something like a dozen different ones in the filter, at least.
There is a leak somewhere on the negative pressure part of the filter. I have a Fluval 204 that did the same thing. I could never figure it out until one day I saw a drip coming from one side while the filter was off for a water change. Since it was off, there head pressure on the filter that was able to push the water out. I took apart and reassembled the filter five times before I figured out that the canister itself had a hairline crack. My filter was an old one so I couldn’t get a replacement part for it and had to trash the filter.
Long story short, there is a leak somewhere. Try turning the filter off for 10-15 minutes and see if you can see any drips coming from anywhere on the filter. If that doesn’t work, then I would recommend replacing all of the o-rings and lubing them up with silicon grease.
Good luck!

I just bought an fx6 within the past couple of months and leaned if there was any sag in the hoses it would keep air in the lines, it may be a seal issue, but I would make sure the hoses go directly up from the canister as much as possible. I took the sag out of my lines simply by propping them upt tosee if it was the issue.
I inspected for leaks and didn't see any. I did clean it out and noticed snails galore in the canister. Malaysian trumpet snails. Cleaned out what I could and will check again tomorrow for bubbles. No sag with the hoses I made sure of this during the initial set up.
Can someone recommend the appropriate grease to purchase since the one I have is not safe? It does say waterproof on the one I have pictured here.

Problem solved! Cleaned the fx6 last night and no more air bubbles. My only concern are those damn Malaysian trumpet snails. Anyone know how to get rid of them?Clean ur media. I only get micro bubbles on my fx6 when it's dirty af
Are you using any filter floss? The only time I had microbibbles was when I used floss and it had clogged up completely.
