Question

i want to get a new filter for my tank but all the external pumps go on flowrate and letres per hours.

I have a 130 letre tank so how do i work it out

Answer 1

Your filter should be relative to the amount of fish in your tank but there are some general rules of thumb - the filter should but able to turn your tank over at least 4 time an hour - so the minimum you should look at is 540 liters per hour. If you overstock your tank, you should go with more. I always maintain you can't OVER-filtrate, but your baseline for filters is 540 lph.
