My DIY chiller design

[SCU33ZE]

finally i made a layout of my inline chiller

im keeping things simple by using a coolworks ice probe chiller stuck to a 1 gallon acrylic tank ,also adding some in/out hose fittings, the out put fitting is at bottom for better cooling performance this will all circulate in a 12 gallon setup
tell me what u think (i made this with MS paint)

too small?,,i dont want to increse by too much my tanks capacity since i need limited weight,,,also its less water for that chiller to cool thus making it a quicker process.

p.s also i just need about 4* F in reduction
