Hello All,
I have recently changed to CO2 misting with a modified impeller on an internal Ehiem filter, and I must say it really smashes the CO2 into micro bubbles, and the plants really seem to love it. My question is this: Now that I am misting CO2 in my tank, my drop checker is going from blue just after lights and CO2 on, to lime green/yellow within about 30 minutes. I am using standard 4dkh solution in the DC and a standard PH reagent. I realize these micro bubbles are getting into the DC air gap and making the color change quicker, so how do I work with the DC and misting. IF it goes yellow because micro bubbles are getting in there, how do I gauge the reading of the DC. The DC by the way is on the complete opposite side of the tank and is not in direct flow output of the EHEIM CO2 smasher. Hope this isn't too stupid a question. Just a side note. I went and got some DI water and mixed my own 4dkh solution, with proper scales and checked it with calibrated tests and went about mixing, checked my solution and it was 8dkh instead of 4, checked it again with another test kit, same reading, then checked the DI water straight out of the bottle and low and behold it has a 4dkh reading. WTF.
This is Thailand(TIT), so all the measuring and mixing was for naught i guess. Although I always assumed DI water should have a dkh of zero. Any thoughts on this will be greatly appreciated. Mainly about the misting and drop checker thing, I'll go to the chemist tomorrow and get a 4dkh solution to eliminate bogus DI water I guess, since I would not know what else could be in the DI water. Thanks in advance for any advice.
Cheers,
Singtoh
