update....framing is about done, still need to cut the angles for the corners and the supports for the middle section.
i ended up not wanting to build dirrectly over the water meter (hidden on the left), so i shortened the tank on that side a bit, however i am going to build a "dump" chamber above that end of the tank for water entry.
i'll then make some cabinet doors below to house some electrical and my mack daddy ph anylizer.
once i get the last pieces cut i'll drill and bolt everything together. then i can start on the actual tank which will sit on top of this frame.
