What size Sump for my 1.7meter tank

Hi all was wondering can I use a 2 foot tank for a sump already have a 2000 liter and a 6000 liter p/h pump for the sump. Please help and advise.

Size of tank is 1690l x 550w x 790h

Rougly about 680 liters

 

I would advise you use a 915mm tank converted into a sump filter rather than the 60cm. Use your 2000l/hr pump and just make sure your overflow, back to the sump, can handle the in flow. If you use a 20mm pipe to pump into the tank use a 50mm pipe to take the water back to the sump.

 

+1 a 3foot tank will work great and will handle the flow rate of your pumps much better that 2 foot. You can buy a standard 3 foot and convert into sump, or have it built from scratch. Should cost around R700 complete with media etc. seeing that you allready got the pumps for it.

 

Any ideas on the type of sump thinking of use prof Dirk sump method. Do you all really think a 3 foot is neccesary?.

 

+1 Scotty hit the nail on the head. I have just done this on my 6ft +-650litre tank. I used a 2ft sump for a short period as I DIY'd the 3ft sump. The 2ft's margin for error in terms of water levels is too small. You can either have too much water which will cause the 2ft sump to overflow if the power is cut and you also need to watch that the water level is not too low (due to evaporation) as you dont want to run the pump dry. The 3ft will offer you much more margin for error and more space to hide equipment.

I built my 3ft sump for about R250. Filter media would obviously add to the cost. I just added two litres of pond matrix which claims to be enough for 800litres of water. I should mention that I have 5litres of ceramic media aswell.

 

You have a lot of water in that size tank. If you want to go 2 foot and it works, then it's up to you really. You could allways upgrade later. Nice thing about sumps hey. If you have 1000ltr in the tank I think 3 foot will be able to turn the water 3 times over in an hour. Only reason I also agree on the 3 foot as a sump.
