One thing to note is that your bps will be different than with a pressurized diffuser. Since there is no pressure in the line (except for the atmosphere), each bubble has less CO2 than if you were...

Red face My "new" 26 bow front.

I re-purposed my Marineland 26 bow front as a planted tank. Most of the equipment is from a previous Aqueon 40 breeder that was up for several years. However, I purchased the Marineland 24" Aquatic...

Same here. I just run the CO2 line into a small hole I made in the inlet of my Filstar pipe. Works wonderfully and so simple.

Gosh, I hope not. So far I've only seen tanks destroyed and small injuries with this type of set up. I'm fearing the day that something worse happens to someone.

My advice would be to stay away....

This should be expected. You are trying to regulate 800 PSI of pressure without a regulator. Even if you replaced the crappy needle valve with a much more expensive needle valve, the bubble count...

The aeration *may* remove CO2 that is being generated from decay within the tank.

Two needle valves (or ten) is no better than one. The needle valve doesn't regulate pressure.

Are you replacing the o-ring on the cylinder pin valve? This would be a good place to start. If the CO2 is coming out of the hole at the bottom of the ASA valve (that little hole is to release the...

On a side note, you might ask yourself about the safety of a system that can blow out like that.

The pressure reading on your lower pressure gauge is not the pressure in your CO2 line. The pressure reading on one of those ASA setups would be 800 psi, but that is not what is in the line. :)

If you don't much care about your fish, then you can use this approach. The problem comes in if your regulator decides to increase the CO2 working pressure, killing your fish. This is much more...

I think the BIO wheels are fine. However, they outgas a lot (LOT, LOT) of CO2.

I switched from 2 Emperor 280 filters to a single Rena Filstar XP2 and reduced my CO2 consumption by 20x (2000%).

Yeah, that's my thought too.

Unless you have very few or no plants in the main tank, I don't see it helping too much.

That link doesn't have anything to do with CO2 degrading parts. What it, or did you just mean to show an inline diffuser setup?

I don't think that is a regulator. It is, I believe, an on/off valve just like the ASA valve sold by this site.

You could attach a sponge filter to the powerhead. This would be a cheap, compact, low maintenance approach that would allow for a more heavily stocked tank than just a powerhead, alone.
