Thank you. I know that it looks complicated and difficult to work on, but really is the opposite. If you will notice, everything that I need to get to on a regular basis for maintenance (filter socks, skimmer cup and waste collector and both reactors) are all located at the very front of the sump. Everything there can be removed in seconds. Reactors are on quick-disconnects. Filter socks just lift out the front and the skimmer cup is super easy to access. I have had sumps where I just put stuff where I had room and as a result, things were sometimes a pain to get to. When things are difficult to access, then you tend to put off maintenance.
