Will looking at the CO2 checker give me an accurate result of if there is enough oxygen in the water for my tank of red cherry shrimps? For example, if the checker is green, do I need to add an airstone? right now the checker is at blue (not enough co2) and i have a diy CO2 setup at a bubble every two seconds. Thanks
 
The CO2 checker may not be accurate if your Hardness is not right.

I have some water surface movement(HOB filter), but i didn't want to put the air stone in because i have a DIY co2 and its working great but i wanted the maximum effectiveness from it. Is there any indication i should look out for to see if my shrimp actually need more O2?
 
I just put the "diffuser" airstone under my hob and there are BUBBLES EVERYWHERE in the tank. The indicator has actually turned kind of dark green (significant change). the shrimp seem to be fine, but i just put the air stone back in (near the top of the tank). Any suggestions on how to get enough o2 but also keep my CO2 at this level? THanks
 
co2 and o2 for the most part is independent. having a good amount of co2 doesnt mean you are low on o2.

CO2 and O2 are independent. If you have plants, they put out O2 during the day. If your CO2 checker is green you are good, if it goes high, worry. Everyone says you can't gas your tank with DIY...so chillax.
^^this one too!

o2 and co2 are independent. the only reason you can 'gas' your fish with co2 is because the concentration of co2 in the water prevents the co2 from leaving their lungs. Thereis still plenty of o2 in the water, it just can't make it through.
 
I agree with the other guys, but if you are really worried about it.. I would put your air pump on a timer and have it run from when the lights go out to when they come back on. Plants produce O2 during the day, just not at night.
