ad aqua
Here's some photos from the surface area of my tank. You can see the oxygen bubbles formed on the surface after a few hours of lighting. They swirl around real slow (I minimise surface agitation to prevent CO2 loss), quite hypnotic actually! You can see the floating plant, Riccia fluitans gives off the most oxygen, the Rotala indica (the red one) does well too. I find my plants pearl most just after changing the mixture in my CO2 units and after adding fertilisers, for obvious reasons.


but my puffers just go
when I give them evil looks...)
