After the global warming trend made my tank hit 94 degrees this summer, I was forced to buy a chiller. My corals have been stressed and most have died, a new MP40 would help the budget and get things pretty again!!!
I missed my MP20. Thought I would sell it and upgrade to a Gyre, but so far the Gyre does not push enough water through so only one corner of the tank get circulate. I would love to upgrade from my Gyre to the MP40.
