You are not going to want to add CO2 to the aeration line. The goal with CO2 is to keep it in the tank for as long as possible. This is done with the use of "ladders" (plastic or glass ramps that run back and forth on very low ramps so that the bubble moves back and forth for a few minutes) and into CO2 diffusers. These trap CO2 under a very fine membrane and purge very fine microbubbles. A good diffuser runs about $100 made from glass. Adding it to an airline would mix it with other fast rising bubbles and expel it to atmosphere before any saturation of the water can happen. If adding CO2 you may want to remove the airstone altogether. You want to disturb the top of the water column as little as possible. Bringing water to the surface will purge it of the CO2 you add.
Thanks for the confirmation that adding CO2 via piggyback will be counter productive... kid of thought so...but needed a second opinion.
Regarding the Pleco...I would love to get one... and one that get's a max of 4" - 8" total. Not too worried about plant's... and I would imagine if the Pleco is fed with an appropriate food... it might reduce the habit of chewing the plant's... I figure the Amazon Sword would be the first to get chewed on.
Not sure the Pleco would care for a PH of 7.6 though... so my search for "bottom dwelling" fish continues... though I am sure it would adapt.
I would much prefer to get species that prefer's the PH...vs having them adapt. (I am sure that's where tank raised is a better alternative here).
Just not sure which Pleco's are more apt to be tank raised vs. from the region they are specific to... is that common info upon ordering?
I planned on ordering my "fish from the net"...
however I have found that there are a number of fish farms here in the Tampa Bay area..and may be taking a drive to one or two of them when the tank is ready.
I have time before the tank is cycled...as you can see from the latest lab's.
