At random spots, throw in your dry fert/supplements like KNO3, or Equilibrium or the likes, get those that don't float. Then observe if they are being pushed around nicely. They need not be pushed all over the tank, but look out for areas where they just float downwards. If there is just 1 or 2 spots then it should be fine, it is quite impossible to always have perfect circulation. But if it is occurring all over the place, then you have to tweak it around. By the way, I personally would have gone for a 6x1.5x1.5, proportionally that is ideal for an iwagami, but that's just me. |

I diy my own rainbar. Got myself some pipes and drill smaller & lesser holes at one end of the it...making it into a rain bar. Figured out that having smaller & lesser holes would push the flow further.
Instead of placing it horizontally, mine's vertical (at both ends of the 422). The holes are on the lower portion of the pipe (the tank) so as the taller plants can consume the CO2 as it raise towards the surface. |
