So you have heavy bio at 80g display and using the Akula 180? Which model UltraReef would you go with on a 180g heavy bio? Let's 2.5x your bio right now. Seems like the akula 200 might be undersized for you right?
BRS has the Akula 200 listed as :
- Heavy Bioload (Most Common) - 105 Gallons
- Medium Bioload - 166 Gallons
- Light Bioload - 238 Gallons
That seems to me like its way undersized for the tank. (Yes I know BRS doesnt sell them anymore

)
Even the Typhoon 200 is listed at BRS as :
- Heavy Bioload (Most Common) - 132 Gallons
- Light Bioload - 396 Gallons
Either they sure like oversized skimmers there or they dont know what they're doing
