i always see people obsessed with having a certain amount of turnover . such as you must turn the tank over x amount of times per hour or youre considered under filtered. my take on this is that surely as long as the filtration you have can cope with your bio load and keeps the water paramaters constant stable and at the required levels then you actually have plenty of filtration.
example i have a 453 litre tank i run an eheim pro2 2028 external and an eheim 2212 internal the external rated at filter circulation 750l per hour the internal i cant find circulation blur for but its rated for tanks up to 200 litres. do the maths thats not 4 times an hour turnover maybe 2 times.
my water stats are constantly ammonia 0 nitrite 0 nitrate 10 to 15 i test every 3 days or so.
so if with less than 4 times turnover in a well stocked sa cichlid tank my water is always perfect even my supposedly fragile golden nugget thrives how/why can it be that you need 4 times an hour turnover??
