I've decided to make a change with the tank. I am going to remove the ugj system. As much as I like it I just don't think it is worth the trouble. I had a nice flood yesterday morning from it. Luckily I was home so I was able to deal with it. Had I been out of town it would have been a very bad thing. I'll remove the ugj system in a week or two, until then it is just unplugged and I have the ball valves closed.
I am now trying to decide if I have any need to add an fx5 to my system. I am pretty sure that the wet/dry and the media reactor provide all the filtration that I need but I am open to opinions.
