Hi guys, been lurking here for a long while, finally posting because of an unexplained problem with my first try at DIY CO2.
I have set up 2X1.5L bottles for my 10g, using a mixture of 2cups sugar, 1/8 teaspoon of yeast(I'm trying to get a slower/more stable reaction). I bought the UP inline atomizer because after looking around, it seemed the most logical/minimalist/effective method of diffusing to me.
The setup goes as this:
___Check Valve_____Check Valve
____3 way 2 switch manifold_____
Double check valve Bubble Counter
__Up Aqua Super inline atomizer__
___Ehiem ECCO Pro 200 Outlet___
It took about a day of seeing nothing before the whole system pressurized up, and after abit of swirling, the co2 bubbles started pouring out from my outlet, and within a few mins, all 10g of my tank was filled with floating tiny co2 bubbles. A little concerned about the whole tank hazing up with co2 bubbles, I disconnected it after 30 mins. Problem is, the drop checker has changed from green to yellow and stayed that way after >48hrs of disconnecting the entire yeast generator.
Worried, I decided to invest on an instant co2 checker from tetratest, and the results returned(after disconnecting the yeast generator for >48hrs) was 10mg CO2/liter of water which seem well within the limits. Now, when I tried to "activate" the yeast generator(made a new solution and connected them back for another day), it just never seem to be able to put any bubbles into the outlet.
I did alot of readup, and chanced upon a 4 yr old thread that shows the following setup to be able to obtain decent constant pressure:
I have not built gas seperator and needle valve portion of it yet, and will probably be doing so this weekend.
For the record, I have a dozen of dwarf corys, xmas moss, algae balls, rotalas and mini salvinia. In the past few weeks, only the rotala seem to have grown(triple in height actually) while the rest didnt show much growth at all. During the entire time, the corys didn't seem to do the "gasping for breathe" maneuver any more than they usually do.
Meanwhile any form of advice or comments to help improve on my system are welcomed!
