Today I purchased a 100 gallon tank for $100(canadian) from a former landlord who had a guy ditch out on rent. For shits he gave me the two filters that were in it - mostly get it out of my sight. Inside was an older eheim internal model (haven't been able to find it). It had no filtration medium in it so I loaded it with extra bio-rings and charcoal I had around (change outs for other filters). And set it up in the 100 moving everything from my 55 into it.
The other filter was a magnum 350 that I am going to in the next weeks attack to the 55 and add in an internal filter (add in water flow to help it out.
I do have a question though - I am familiar with eheim products (had one many moons ago - albiet smaller) - however the magnum series I know nothing about. Do I need a filter medium for this as well or is it pretty much a plug an run with minor maintenance? Also is there any quirks I should know?
(The 55 will be housing my smallest turtle as the larger two are beginning to pick on it)
