Powerhead creating millions of micro bubbles
I have a TopFin 50 Powerhead in my 75 gallon. I only have it to defuse for my CO2 generator. I haven't had this bubbling problem until now. It is a constant flow of millions of micro bubbles.

I've taken this powerhead apart
Turned it upside down to see if any bubbles came out
made sure nothing was blocking anything
and I even remade my CO2 mixture

So far, if I take the intake from the CO2 off the powerhead, it maybe there's a leak in my bubble counter?

Ideas while I try to seal this bubble counter?

Anyone have any ideas?

Just a thpught, if your using the powerhead to defuse the co2 bubbles then wouldnt it be the smaller bubbles created??

Yes, but I've never had the bubbles created before. The powerhead and suddenly started giving these constant bubbles.

I wouldn't mind them too much if it was a small amount of bubble. But it's like MASSIVE amounts of constant bubbles!

ok, try this to make certain where the problem may be.
Simply unhook the CO2 line from your generator and clamp it shut, you could use a small C-clamp or a pair of vise-grip pliers. If you still get the microbubbles in a few minutes after clamping, you have a leak somewhere. Keep (really securely) pinching off the line at points, moving closer and closer to the powerhead along the line. When the bubbles stop, you know you are past the leak point!

I'm assuming you are using pressurized CO2 for a 75 gallon? But you mentioned mixes and generator...
The DIY mixes won't really deliver any kind of consistent or adequate CO2 levels, especially for something as large as a 75 - unless you have some kind of massive generator!

No, it is just a small DIY generator. I don't have a massive amount of plants or high lighting so I am only using 1 small-ish generator. I've actually gotten excellent growth thus far, so I am not increasing CO2 until I get higher lighting.

I'll give the clamping idea a try!

Okay, I clamped my lines. There's no leaks. The silicone I had dried up -.-
I'll have to get some more and seal the hole on the bubble counter. I don't think it's the 2 liters because they're producing a bubble each at a rate of 3 seconds. So it 1, 2, 3, bubble, 1, 2, 3, bubble etc etc.

So I'll get a small tube(if I can find one xD) at home depot and seal the cap.

Well, sealing the bubble counter didn't work. So I exchanged in the powerhead thinking it is just too powerful. It is rated for a 50 gallon. I traded it for a powerhead rated for 30 gallons. And no more bubbles!!!! WOOOT!
