Wow it's amazing how much flow you lose the further you pump water
When I set up my tank I got 4 x eheim compact 5000 pump which pump 5000 lph
So I thought that should be good that's 20000 lph
Then when I turned them on the shortest pipes were about 3ft and it was real powerful
Then I turned on the pump that went throw 4 x 25w UVS so had a total of about 10 ft of pipework to go throw and that pumped slow out of a 5000 lph pump I was probably getting about 2000 lph but that didn't bother me to much as slow flow via a UV is better than to fast
Now the far end of my tank was the problem as the total pipework was about 12 ft with 2 outlets with one 5000 lph pump on each and again I was lucky if I was getting 2000 lph out of each pump
This was giving me a total turn over on a 1000 gal tank of maybe less than 1000 lph which was a joke as on my old 350 gal I was turning over about 9500 lph
The strange thing was even with such a low turn over the tank was staying clean
The sump is big with loads of media probably ove 100 litters
So I made up my mind that I need more flow but found you lose loads of power the more head height you have and the space in my sump was giving me problems to find a pump that had power a good head height and was small enough to fit in my sump
I found a pond pump that was 18000 lph with a head height of 15 ft I know I'm going to lose some power due to the length of pipe work but I put it in today and it's pumping so much better than before
Anyway I will give it a few days to settle then I will let you all know if flow is that important
