55 gallons beach cycle

!±8± 55 gallons beach cycle

I'm in the hobby for about 3 years and was the beginning of a new tank of 55 liters. I order 2 Hydor Koralia circulation pumps over 750 gph each race and are arriving by mail soon, I do not know what pump to use for my oil pan, a koi pond pump $ 30 or $ 60 Hydor L40, both of which revolve around to 750 per hour, but the pool pump has no guarantee to subscribe, please let me know what you think Rate, please comment and always nice to thank
