[APD] The most simple C02 reactor yet!
Simplest reactor yet.
I was using a powerhead, as you might have seen me post earlier this
week. I was using around around a bubble every 3 seconds or so. I was
reading online about diffusors and reactors and came across one post on
the Krib. See:
Power CO2 reactor (DIY)

I thought, why use a powerhead at all? I already have a spraybar coming
off the Eheim, so why not just cap the end and tap into it. So I did
just that. I found a 5ml test tube cap and it fits perfectly on the end
of the spraybar. The Eheim originally came with one, but I or my cat
misplaced it long ago. Opposite to the holes running along the bar
(bottom) I drilled a hole (top) and pushed in the C02 airline directly.
It took took maybe 10 minutes to complete and that included locating a
suitable spraybar end cap and a drill bit.
It's extremely efficent and I'm going to have to build a bubble counter.
The C02 stretches along the top of the bar and burps every now and again
but I'm trying cut it back. Again, I need a better needle valve for
control. In the 20 minutes I was playing with adjustment, pH dropped
0.1. If I'm not mistaken, that's a fairly high infusion rate for a
I need to build an inline counter pronto. I've seen online directions
before, but misplaced them. Links anyone?
