So far I'm liking the hydros controller I can start to see the limitations with it, but for right now its still more than I need and use, so it is working great for me currently. I just put the same set up on my 48g, so yes I like it I just wish the wifi plugs made better decoration.
So with the controller I am really starting to pin a good temperature that is efficient to run the system at where the heater and chiller don't run as hard while still keeping temperatures under 80°. I have the temp sensor in the sump first chamber and the tank temp sensor is 2.5" below the water line in the corner of the tank in the shade. I wish it was possible and i could do more with the heater and both sensors, but right now my heater responds to the sump temperature sensor which is the "temperature sensor" so far its pretty stable at a .4° difference, the chiller is 5 120mm fans hanging from the lights and a small fan in the sump.
i Haven't changed anything despite the dinos, but they are probably a week or two out on going away. Added to the frozen amount weekly w/mix of other food/ stopped dosing flatworm stop/coral boost. Low nutrients.
