I'm setting up a planted Spec V. In researching the best place to run your CO2
due to the lid design, the only place I saw suggested was under the filter media right beside the pump. I set it there last night. I see micro bubbles in the water following the water flow, so it looks like the pump is taking it up and sending it through the outflow like I want. My main question is I read something about CO2
affecting the BB. Is that a major concern? The tank isn't cycled yet, haven't even started-- been waiting for a few things and figure I don't need a cycled tank to start planting-- so I obviously have time to move it if necessary. I don't know where I would, though. The top is not conducive to having things in the display area lol.
The pic shows the red dot where the diffuser is currently placed for those who like visuals. The pump is literally right beside it.
