The 29g rant
I'm so looking forward to the day I can turn mine into a sump for a tank that doesn't feel so cramped, say a 75-120g.
If you're thinking about a 29g, consider:
- it isn't thick enough to really allow for foreground, midground, and background planting. Two of the three, sure. All three? Nope, not in my experience.
- flow is weird, probably because of the shape. Even with a 2217, I still need a Koralia nano to hit dead spots. Yeah, it does have a reactor and heater inline and the spray bar is aimed upward to maximize O2, but still.
- lighting fixtures are awkward to find (most lights are in 24", 36", and 48" lengths) and 30" T5HO bulbs are even more rare, if they exist at all. I had to get offset 24" bulbs in a custom case.
