Flow through diferent blocks are (nearly) always different. when tring to compare two things differences have to be taken into consideration. and seeing as flow makes such a
big difference to performance, it's very important. it's the biggest variable there is....
Compare two blocks with a Eheim 1250:
Block 'A' might run 3degC hotter than pump 'B'. you'd be inclined to call pump 'A' shite, but if you ran both blocks with a 1060, block 'A' could run cooler than (the previuos best) block 'B'. the 1060's flow could make all the difference...
So would it be a safe bet for a reveiwer to tout block 'A' as shite?. considering not
everyone(though nearly
) runs a 1250 Eheim?...
That's one reason, bet your ass there are more
...
Basicly to be comparable they have to have
the same amount of flow through each.
I kinda know what you're thinking( I think!!). the flow through is part of the design and therefore should be taken as such and ignored. that would be OK if flow was'nt so bloody
variable from pump to pump, and a reveiwer is trying to cover ALL bases
