First off, this is an excerpt from my tank journal. Figured I might as well post this in the DIY threads. Thanks to all of you!
ok, so I hooked up my DIY co2. I am distributing through an airstone (i know this is the weakest way to dissolve it) that is situated directly under the intake of my filter. Before the co2 started, my guppies and shrimp were quite lethargic. Since it has been running however, they have become much more active, exploring all over the tank instead of hiding under the filter or by the heater. I was wondering if their behavior was changing due to an adverse affect of the co2. (diy from a 2 litre bottle). Is there any danger of too much co2 in my 20 gallon from this setup? Any help would be great thx.
I would think the opposite, it is good: the little extra CO2 was just what the plants needed, so they are raising the oxygen level in the water. Probably not pearling, but adding enough O2 that the fish are happier.
funny thing is my drop checker is always light yellow-green and all i have is the hagen canister changed weekly fed directly into my intake. I just ran the airline tubing down to the intake guard, cut it on an angle, so as it starts to bubble out the suction of my xp1 pulls it in. My tank is about 29 gallons
