Polywise's 300 glass reef with equipment room

Sounds like you have a best case situation here. It would be interesting to hear what you brother in law has to say though. I havent heard a lot about the subject of weight on the flloor and that maybe because we are way under what the home will handle in most instances. Love the thread though please keep us informed on this build!
 
Question to brother in-law:
Hi John,
I have a fishie question for you.
I am going to be placing my fish tank in my living room.
when full with water, it will weigh 4,000 pounds. The foot print of the tank is 60"x36" (2,160square inches)
doing some math, that breaks down to 1.85 pounds / square inch sitting on the floor.

It will be against the wall that our christmas tree was on, and the floor joist run perpendicular to the 60" tank length.
Do you think I need to support from underneath?
Jim C.

Answer from brother in law:

Jim

Floor loading is usually designed for 50 lbs/sf
4000lb over a 5ft x 3ft area is 266.7 lbs/sf ( same as 1.85lbs/sq in x 144sq in's)
You definitely need structural support underneath. Does not matter what way the Fl jts are running. What is in your favor is that you are next to the main girder in the middle of the house
jm

my conclusion
I have to start investigating this before I put water in the tank in the living room.......
 
I don't know, but he came up with his answer. I quicky did a search, and found these (2) SUBG, and table 3
both seem to be in the area of poulds/ square foot that he is mentioning

got to think about this a bit, might have me changing location of tank from living room to basement....

How about a micro lam beam and some lolly columns? If it is above the fish room, you may just have to move some gear to spot them. That said, nothing wrong with a cool reef tank in the basement!
 
BAX,
That is probably what I will end up doing. Tank is not directly above the newly constructed equipment room. The only down side is that columns will be in the middle of my already reduced space that I was allocating for my work room. Easy choice to make though, as I really want to see my reef tank daily without going out of the way to see it in the basement.

4000lb over a 5ft x 3ft area is 266.7 lbs/sf ( same as 1.85lbs/sq in x 144sq in's)

Where did you get that information from? I should have fallen through my floor millions times.
The information is CORRECT...with an explanation. The 50lbs/sf, is for the entire room...for example a 12' X15' room = 180sf = 9000 lbs...the floor is designed to support a TOTAL (distributed) weight of 9000 lbs. The problem with fish tanks is that ALL the weight is in a small area approx 10-12 sf. I have had a structural engineer to my home twice..for a 300g and a 450g install. Both required extra support, for the 450, I decided the basement was the best option. I believe, any tank/sump combo, over 200g, SHOULD be re-inforced, (not necessarily extra column support, maybe just doubling up on joists) better safe than sorry.
 
polywise I appreciate you posting that info. I would assume that those of us with a crawl space would probably need to pour a footer of some sort and brace up the floor. Hope you can come up with a good solution.
 
The guys came to bring the tank in the house today. Went off with out a hitch.

I borrowed some suction cups from a fellow reefer, and the mover came with 4 guys to move the tank. I was told by the tank builder that the tank weighs about 400 pounds. Glad that the move is over, and nothing got nicked or chipped during the move.

Now it is on to building a canopy for the tank. I have (2) 20amp circuts
pulled to the ceiling area for lighting.

Something I was planning for actually came out as planned. I just checked, and the height of the tank is just at my arm pit. I tried to get the tank as high as possible for viewing, yet have the ability to reach the center without getting up on a step stool.:D
 
Tagging along. I had the same situation about tank weight on my living room floor & one of the members provided me with this link, very informative - http://www.cichlid-forum.com/articles/aquarium_weight.php

I used two floor jacks ( the construction types) from menards & used two 8x2's to support the beams. The floor has not shown any change in gradient over the last one month since the tank was filled with rock/water/all equipment.
