i did the calculations on there dont know what they mean or if its good or bad.9.64 feet of head pressure.4.16 psl.flow 628 gph

 

[duke62]

the 9.64 is total losses of head pressure.and i forgot to write 38 iterations whatever that means

Why don't you consider an external pump so that it dosen't heat up your water by 2-3 degrees?

i agree with pecan.. i went external with 2 returns both split with 2 loclines on each inside the tank and my external works great... and heat is lowered compared to how hot my mag 9.5 use to heat up the water ... the choice is all yours...

You might want to consider an Ehime pump as well. Quite operation and runs coller than Mags.

i used 2 external genx pcx 30 pumps had great flow. and if one pump ever fails you still have another to back you up
