Since I've added a bit light and started using Tom's "Tiny Bubble" method of co2... hehehe I have experienced some great results

First the greenwater is gone. Yeah! Still a bit of algae see third pic below.
some of it datom which i'm not sure why its lingering.

in the first two pics please notice the differenc ein the new top growth compared to older growth from where I got them from.

The green spot will not come back if your Co2 levels are good (which they appear to be by the plants) and you keep enough PO4 in the tank.

the green spot is the GW? cause the GW went, but the stuff in pic 3 is new since or rather as the GW left.

Thinking about going up to a Jebo/Odyssea light like 96w
or soimething... so hard to light 30" tanks

Ian, many folks have been seeing the same results, yet the mist method appears to waste more CO2 than the other methods.

Adding venturi loops on the external reactors also depressed the pH about 0.3-0.4 pH units with no other modifications(no flow rate changes nor in tank changes). Response times are up. No bubbles are leaving these reactors.
Now how could the pH drop by firing the gas into a recirculating loop that increases surface area?

You can definitely see and measure a difference using these two methods either in conjuction or seperately.

I'll have a rate of dissolution of gas bubbles at different dissolved CO2 levels shortly(I am presenting the data along with DO readings in the BarrReport).
So we can have a measurement of how fast the CO2 bubble last and the method is pretty good and robust in terms of accuracy(quite unlike a bubble rising in a long column)

Using several good comparative methods helps lend support and helps to better understand the dynamics that are occuring.

Regards,
Tom Barr

Tom,
Yeah I just started pressurized and I see now the difference between 2 bubbles per sec vs DIY 2 bubbles per sec. I thought there were alot of bubbles before! lol

True it does waste more. but I cant say i care at the growth rate I'm getting. And i'm at 2 bubbles per sec and every inch of the tank is covered with that one powerhead. If I did use a reactor I'd still use 2 bubbles per sec so... to me it's not a big deal the results speak for themselves.

AH! i need tog o over and subscribe, some plant sales have left me with enough to finally become a member. Yeah, I was gonna build a reactor until this method was working for me. I hate to try to fix something thats working so well.

i even turned off the co2 today for about 10 or 15 minutes and i still had a champagne glass from the pearling going on. I'm still not seeing the quicker pearling. It's still taking my riccia about 3 hours to show bubbles at the taops of the leafs if you can call them that.

also in the third pick what was called green spot, if you look close theres a green blur, it's a tuft of what in the algaefinder looks like filamentous. its worrying me, but it isnt too prevalent... yet...
