I thought I'd throw up an update for those interested in a project like this.
Well, so far so good, it hasn't exploded yet
My only real issues have been with my C02.
A small freek dump which took out 20 of my Congos and all of my Clowns
The Clowns have been replaced but not the Congos.
I had an EBay solenoid go bad and the plastic C02 supply line started to crack. An order to Rex Grigg solved these issues.
I still LOVE my dual FX5s; great for the money and I haven't had a single issue. Currently I'm only running the supplied outer basket foam with a couple of ceramic bio rings. I did notice that the flow would drop off rather quickly with the center foam media, hence the reason I don't use it. My water is clean and crystal clear, so I think I'm doing just fine with the outer foam.
I did end up going with RO water for other issues, but it was an unplanned expense. I went with an EBay 75 gpd, 4 stage RO setup with an Aquatec 8800 booster pump. I like to think I have a pretty good reservoir setup also. It is a 50 gallon barrel in the garage with a heater, Quiet One 800 circulating pump, and 9.5 Magdrive pump for filling
I can't take a pic to save my life but here is a semi current one. I have a couple of different plants in there now, but nothing major.
More pics can be found in my signature. Please feel free to ask questions if you have them
