MP40 upgrade asking for trouble?

[db1317]

I have a 75G Reef Ready with corner overflow. I have an MP40 running at 60% on the opposite side of the overflow/return. Opposite the MP40 is an MP10 running at 95%. I've had this powerhead configuration for about two years. My tank is SPS dominant and have grown many small frags into colonies and I feel like I now need more flow. So, I upgraded the MP10 to an MP40 and will be running in AntiSync mode opposite the existing MP40. I know that SPS like stability, so am I looking for trouble by upgrading? Anyone have a similar experience? What are some very early signs that I should look for if the corals aren't happy about the change? Thanks in advance!

I'm sure they will be loving the extra flow.
Maybe u can just keep it low on say 40% for a while, just ramp the flow up slowly.

Only signs I think you could look for would be lack of PE and tissue being stripped off
