Adding sump tank help..

[dirtnitro]

Hi, I have a 2 ft by 1 ft by ht(1.5ft) as a main tank, those normal tank you get from LFS, this is not a custom tank.

I will like to add a sump tank below it my question are:

1) How do I extract water from main to sump? by gravity? If it is then when there is a power failure, will it flood my floor?

2) I do not wish to drill hole to my existing display tank as it is more expensive, any way to do about it?

3) What should be the flow rate of my return pump?

4) How many compartmnet shall i have, if i custom made my sump as 1ft x0.5ft tank

Thank for advise

1) you can use a overflow box

or

http://www.reefdepot.com.sg/AddProduct.asp?ProdID=314 to overflow to let it "suction and siphoning" it from main tank to sump tank.

else, if you wanna use pump and piping, you need to place one small pump from the main tank -> sump tank (another pump to pump water up).

However this is more risky as if one pump is not working, the tank it's in will be overflowing the other...

4) pump compartment can be normally 3, first compartment is the mechical filter, 2nd compartment can be refug or skimmer, 3rd compartment is water pump to pump the water back to your main tank.

Else, you can use a external canister which most sumpless tank will use.

Thanks, I am using external canister currently and realize the nitrate level is very high even I change the sponge and do a water change after few days the nitrate is back again, can I replace the media in external canister with LR instead of using a sump?
