I just got my son a red and blue betta (spiderman) for his birthday. The Topfin tank I bought has an undergravel filter system. The directions were lacking.
I have a stupid question. Should I fill the water level in the tank above the top of the filter riser tube (so the airbubbles mix with the tank water)? Or should The water level be below the riser tube (so the "dirty" water stays in the riser tube) Is this even how the undergravel filter works?
We've only had it a day and the water has a color to it...
Thanks
