Marc`s 120g build from A to Z

Today I climbed under the floor to examine the joists and see if they would need bracing to hold the load of the new tank.  (sighs) I don't know what they were thinking, near as I can tell my present kitchen and bathroom were not original parts of the house as they have steel I beam supports every 5 feet on center starting at a triple stacked 2" X 10" support (where the foundation wall used to be.). There is a main support beam which is also triple stacked 2" x 10" it's located 5 feet off the front wall of the house, the joists are only 2" x 6". I should mention that my current tank which is being replaced by the new tank is located on the front wall between  that 5 foot span . I have a few options open to me at this point I will decide and include pics of everything I do and post them here.

Center from main support looking at wall.

 

Update: The supplies to add support to the joists are here ( Two 12 x 8 x 12 deck blocks, six 2 x 4 x 8 framing studs and 1 lb 16D framing nails ) I am going with nails and not screws because I didn't like any of the screws they had which were decking and drywall, not a huge selection during winter I guess. I also went with 2x4's because there is a main support beam five feet from the wall so this is just extra support, I think the five foot span can hold the weight of the tank which spans over 3 joists and this is just precautionary measure to stiffen the overall five feet. I am off to bed as work was long last night and it ended with a physical *Cough* The joist support work begins tomorrow I will upload some more pictures as I know this type of work seems to come up a lot in this hobby and just a little background I worked in structural steel as a welder for 11 years so I am not doing this blindly.

 

The cat decided it was time for me to get up, so I got the deck block installed and leveled ready for the beams. The span of the tank is over 3 joists so I placed base supports at joists 1 and 5 ( one joist extra to left and right of where the tank is going.)

 

One more stud and it will be Done, not thinking I need and X bracing.

 

Update: the joist shoring is now done ( no pic) as I was under there I also had to repair an HVAC insulation tube that fell off a floor register and there were a ton of spiders. Use imagination and add one beam on the left side of the last picture /DesktopModules/ActiveForums/themes/_default//emoticons/tongue.gif all the tacing nails were removed and replaced with 3½ inch wood screws Next order of business is the tank stand, which I am waiting to hear back about the specs of the tank. I have looked around and I have found 3 or 4 measurements all different for the same tank so I am wanting solid numbers before construction can continue. The stock list of wood on hand for the tank stand is two 4 x 4 x 6 and six 2 x 4 x 8 for the framework which I am excited about seeing I won't have as limited space to work as the joists, no spiders and no sand!

recapping where I am at on the big picture.

I re did the slope to direct any water leaks to the center used a 2x4 think I did a pretty good job lol

 

Everything has arrived lights, wavemaker pumps and protein skimmer came on Monday. Return pump and live sand came today..... it looks like a UPS truck exploded in my living room. Not sure if this matters but my live sand was partially frozen and 1 bag was frozen solid anyone know if this impacts anything?
