Water Movement
Looking to improve upon my first 110 reef water distribution design
I took my lessons learned and set out again to incorporate
things I have seen others do successfully with my own jaded thinking
 This led me to this 2nd grand experiment.

The Pump
 The main pump in my system is an Iwaki
 it is capable of pumping 1110 GPH at zero head
This pump is situated in my basement
 and is fed by the 40 gallon Sump/Refugium/Skimmer
 

The Distribution System
After the water leaves the basement it arrives here at the
 back of the tank and enters the Ocean Motions Squirt 2 way
This 110 volt device essentially gates the water flow though
 first one outlet and then the opposing outlet on a 1 RPM cycle. 
I am hoping this will supply the wave action and random
water flow the inhabitants relate to in the wild
 

The Standoffs
Each OM Squirt outlet seen above enters the tank
through a drilled 3/4 PVC bulkhead opening
then turns down and runs to the bottom  of the tank
each "standoff" is about 4" high with 4 holes drilled into is side.
My hopes are the "standoffs" will work somewhat like penductors
by dragging water in thru the holes and moving
 a larger volume of water than the 3/4" outlets alone
If not then they are just wider standoff bases for my live rock to sit on
 

The Surface Skimmer
After the pump has filled the tank to capacity
the water will fall over the coast to coast surface skimming overflow
I created this by cutting nearly 50 teeth into a sheet of 1/4" Lexan
 I then  attached that sheet in front of the bulkhead fittings
 and to the side and rear tank walls with black 100% silicone
Behind the Lexan is a trough created by the silicone sealer on the bottom
the tank glass wall on the back and the Lexan on the front.
The rear wall of the tank has (5) 1" holes  to feed the external overflow
 

The External Overflow
After the water falls thru the (5) 1" holes
the water collects in this box and
 the drain will direct it back down to the basement.
