New tank build

[Bent17]

Hi all - Planning my upgrade tank and would like to see your opinions on my hardware list.

Return Pumps x2 Redsea 12000 (Do I need two or can I get off with one?)
x4 Mp40
Reef Mat 1200
Skimmer: Deltec 1200
UV: Deltec 48W
Chiller - Teco 1000 or should I go with Teco 2000 for 850L?
x2 Titanium 300W with controller
x3 Radeon XR30 G6 Pro with Orphek OR3 Blue Plus

Let me know what you think and if I should include anything else or not.

Please refrain from the Redsea comments I have a 425 G2 for 4 years and no issues to report.

 

[MetallicInk]

is this about gear upgrades for the 425 g2 or a different tank?

 

[Gumbies R Us]

Do you have an ATO?

 

[Bent17]

Upgrading to an S-850 G3. So most of the kit will move from 425 to 850 unless to small or out of spec and yes I have the RS ATO also
