As i got this 2nd hand from a Aro keeper, there's a lot of changes to be made.
Problem that i see so far:
1. The pipings seem to be small?
2. the return outlet in the first picture, is at the bottom.
3. if i were to change the piping to bigger diameter, what will happen to the part where it is silicon to the tank? will it fit to the new diameter?
4. What return pump to use? Eheim 1260?
