yes Steve
I read a lot on reactor and found that people who have problem with there reactor was the one who have to small pump on them the media clog the feeding drop,lower PH,big comsumption of CO2......... + I love those 3md they are built for life and need no maintenance they only draw 1 amp. silent and cheap
I have a 3md here that run for more than 7 years never stop clean once a years the impeler, my mag18 on the skimmer need to be clean each 3 month if not it jam and the bushing turn inside the pump ans scrap the pump
