I am considering buying a tunze 9020 Unfortunately it is set up for in-sump use but I want to convert it to in-tank use, the problem is the guy selling it cant find the parts for in-tank use. Does anybody have advice on jerry rigging a conversion, or perhaps someone is using one in-sump and has no plans to ever use it in-tank and can sell me the parts. I have looked over the tunze website and getting all the individual parts would cost a bundle. I have a 9010 running right now on my 80 gal and want to try a 9020 on my 330 gal in tank, in an effort to go sump-free
