sounds like a good idea but id run the drain hole a lil lower like 8-10" off the bottom panel centered that way it can evenly suck water from the lower part of the tank ....
the returns sound fine its all a matter of prefference....
as for my tank i have 2-1" holes drilled on the center of the panels one on each side of the overflow box centered in the back panel.... they come out and 90 to the center where they join up in a 2" T then straight down to my Sequence Dart pump that shoots the water straight back up to my OM-4 way which sits at top of the tank then the four returns 2 up top and 2 in the back upper hand panels but i lowered them down using PVC to give more midsection flow in the tank... seems to work out pretty good IMO
Murph...
heres what i'm going to run for my closed loop return pump.
Coralife Turbosea 1100 gph high pressure pump. i'm going to mount it right under the stand to get the most pressure.
my other question was , i've talked to many people and everyone has different opinions about the 2 holes compared to 1, most say 1 the same size as the return in, which would be 1", i was planning on having the same exact plan as you have, with 2 90's down to the return then back to the top and across the top. i havent configured how much loss i'll have with the runs to the corners and the same amount of 90's youy have.
as far as the holes you have, in reading do you have them drilled in the sides of the returns or the back of the back of the tank ?
do you have a pic, that would be great
thanks a lot :joy:
