Dmaaaaaax,
So how come you arre using two filters?
Second is the 400w Hydro heater an undergravel heater?
Another question: Is the sudstrate only the flourite gravel (and how deep). It looks like there is just plain type of gravel. The color looks different then all the flourite gravel i have seen.
Sorry if the questions seem basic. I have decided to use your aquarium as the model for my aquarium.

and lot of this is new to me. I am just getting overwhelmed by all the stuff out there.
thanks
