Skimmer Pump
ATO Pump .5 ;D

 

for my 85g
1 return
1 skimmer
3 ph

my 265g
1 return
1skimmer

A better question is how many do you have not being used?

 

For my 125, I have a Snapper, mag for skimmer, and 2 Koralia in DT

 

1x Mag 9.5 (return pump)

1x Gen X / Mak-4 PCX40 external (drives manifold to the skimmer, 2 x UV sterilizers, PO4 reactor, chiller, and output to drain)

2 x Ecotech Marine MP40w's w/ wireless wave drivers

1 x aquabee 2000/1 (recirculating pump on the skimmer) if that counts?

so i guess 5 total

 

72 bow
2#3s
2#1s
