Shrimp Rack Setup: What will you setup with these equipment for CRS?

[Sianzation]

3ft x 1.5ft width stand
Eheim 2026 1000L/H canister
Hailea 1/10HP Chiller


Will be getting a 3ft x 1.5ft stand and will be using the 3ft x 1.5ft space on top tier. Bottom tier will be used to put chiller and canister.

will be using 10mm glass to maintain water temp better.

Plan A: 10mm glass 3 ft x 1.5ft x 1.3ft tank (for CRS)

Plan B: 10mm glass 2ft x 1.5ft x 1.3ft tank (for CRS) + another tank 1ft x 1.5ft (for other shrimp)

Plan C: 10mm glass 1.5ft x 1.5ft x 1.3ft tank (for CRS) + another tank 1.5ft x 1.5ft (for other shrimp)


considering the above with the chiller running time.
I assume that if i am using Plan C, 1.5ft x 1.5ft tank with 10mm glass, the time taken for the chiller to kick in again will be longer.

Which will you go for if you have a choice?
