Hi everyone...I never fully or successfully setup a sump before because i always only had many filters and fish only tanks....this time need a sump.....

I need help on 3 questions....

1. How does the water flow out of the tank into the sump...with gravity or pump???

2. How does the water come back into the tank???

3. What happens when return Pump does not work and my sump is filling up with water?

Thanks guys.......

= gravity

2. How does the water come back into the tank???

= pump

3. What happens when return Pump does not work and my sump is filling up with water?

= using Internal Overflow System which is partition in main tank and water wont overflow when pump stop. It also has a hole drilled to let water gravity go down to sump. Please refer to website as they are more professional in explanations.

1. Use overflow system

2. Use a return pump.Add a one way valve to prevent siphoning action when pump stop or spoilt

3. Will never overflow once tank water level is below overflow
