Setup for 5' x 2' x 2.5' ok?

You might want to consider the chiller flow rate before you buy your filter. You might also want to have 2 CO2 outlets... 2 MH lights might not be enuff... depending on what plants you want in your tank...

pardon my ignorance, would the chiller have in-built pump, or just pure collant and coil? hoping to salvage my Eheim 2026 which is 1 year old

2 x MH of 150W each not enough? ... say for riccia or high light stem plants???

Chiller do not have built in pump. Use the output of your 2026 as a pump.

I believe it should be more than enough.
There is a saying that 3W/G guideline is too much for big tanks and too little for small tank. Don't simply stick by it. Try it with different heights before buying another.

I remember I had a link that had some theories on it.... I post it when I find it again.
