As Above ^^^^^
The biggest is the best when it comes to filtration, with the minimum of 25% of the tank volume, always go bigger on pipe work incase you want to fit larger pump/s in the future, i will be using atleast two 2 inch pipes for the overflow, i am using a 3500g pump as it what i have at hand, i will more than likley add another at a future time.
I maybe lucky but i am also building a filter room for 200g sump and external pool pump with maybe a sand filter also as i have one spare, i was going to build a Koi pond, the reason for the spare bits.
PS,your kelbri is awsome mate, going to see if there any around, mind you was hard enough to find my Ocellaris.
