200LPH to weak for single loop?

[Markistehnamezor]

I want to do a two loops in the 900 since I will mount a TC160 radiator below the 200mm fan.

I will use 2 of these.

First loop will be: res/pump>TC160>GTZ>res/pump
Second loop: res/pump>FC EK4870>MCW30>MCR220>res/pump

Will this pump be too weak for those setups?

Thanks,
