You'll find people disagreeing over turn over rates per total volume for your tank and sump .
As far as im concerned a higher turn over rate of water back to the sump for filtration is better than a lower one ,
Simply because if you have lots of fish/bio load i'd rather turn the water over more than less.
And if you desire to cut down over all flow it's easier to install a valve in front of the pump ( that cost you money ) to cut down on water turn over .
If you find you need MORE turn over , guess what ?
You can put the pump you just bought for 150/200 clams in storage
and lay out another sum of moneys for a larger pump , simply because the smaller one was'int enough in the first place.
And not to even mention the fact WE ALL desire
clean crystal clear water, hence more flow can move miore water back to the tank for "FILTRATION".
I'm not saying turn your tank into "wave world" here
just you mght consider the "down side" of lower turn over rates. |
