MP 40 (old one) anything I could/should upgrade?

[IPT]

I have an MP40 on my tanks and have for about 5 years now (maybe more). At the time i bought two, but turns out one was enough. now I'm moving everything froma 75 to a 120 and want to use both. I have the old school controller with the buttons on the bottom and twist know for flow speed.

So, is there anything that could/should be upgraded? What would I gain or should i just go with the two old school ones and call it good?

You can upgrade to the EcoSmart controller for $130 each. By doing that it would give you a couple of extra mode with the Nutrient Transport and Tidal Swell modes. You will also be able to access them with reeflink and control them through Ecosmart Live. I also had a few older models and have since upgraded them, it's well worth the expense.

thanks for the input.
