Thats the SUNSUN also goes under Aquatop i believeI'm not sure what brand that one is.
I agree Eheim or Fluval but they are pricy you might find some used ones Eheim Pros the Maintenance is a little easier then the Eheim Classics bc the classic has no trays for Media that's why I went with Fluval easier Maintenance,if i didnt get the fluval as a gift from my wife i would have went with Eheimthe one is use is the Eheim 2217 without a doubt any Eheim canister filters are the best on the market IMHO
