Hi Basil and Tekk,
I have the Spec V and 2 Gallon, as I have them side by side on a windowsill facing southern exposure (filters on furthest ends) Both fully planted in gravel and using Seachum ferts.
I see you have the light upgrade.. looks really nice!!! I am not too satisfied with stock lights, tho I get plenty of sunlight.
Last night I got a used full sized CO2 set-up. Gauges, solenoid, reactor diffuser, bubble counter, timer, paintball tank adapter, tho considering a full size tank. I want to get a diffuser, a two-way and extra bubble counter so I can do both tanks. So far just a Betta in the two gal and a couple small Nerites in both.
