i have the regular HOB remora skimmer and currently using a maxi 1200...
i was thinkn about upgrading to the mag 3... i emailed aquac about it to see if that would improve the results any but i'm still waiting on a response.
anyways, i have an extra mag 7 i might not be using, so if you wanted to do a trade + little bit of cash, let me know
my mag 7 for your mag 3 + ~$10 , PM if interested
