I will let you know how it works long term. Right now, I have my MP10 on the left side and the Nero on the right. In terms of footprint, the Nero is slightly larger than the MP10 but smaller than I anticipated. The water flow on the MP10 is very dispersed and I think it beats the Nero on that front. The MP10 is at 50% on reefcrest and the Nero is at 15% on random mode. Considering my MP10 has been more or less flawless in the 4 years I've had it, it will be very hard to beat the reliability and performance of the MP10. The only two reasons I did not get another MP10 instead of the Nero was because 1) I love buying the latest gadgets and 2) Eventually I will move out of my small apartment and upgrade to a larger tank.
In other news, I have performed a few large water changes, added some polyfilter and replaced all of my RODI prefilters/DI resin. I am hoping that brings down some of the heavy metals the ICP test detected. My corals have responded well and the pink lemonade colony has regained its polyp extension. I also added a torch coral to the sand to add some much needed movement to the tank.
