thanks
 

I guess it sounds like it is good to go.

Again though, does anyone know how to tell where the floor joists are???

:mrgreen:

You don't really want to know WHERE they are rather which direction they go.

What's the ceiling like under the spot? Drywall? You could try a stud finder but I'm not sure if you can get any that will read through stipple. If nothing else you can try the "tap tap thud" method. The empty spaces will have a deeper resonating sound, but will be a thinner thud sound where it's contacting the joists.

OK, thanks all...

lol i didn't even think of this, im sitting rougly 700lbs over 3 feet or floor in my 65gallon tank. Good things is on an main wall with support beams supporting it.

:lol:guess my post are invisible:lol:

Probably blocked you Doug... :razz:

Doug, the problem is that people don't think your posts are serious if they don't involve at least one "mang" and possibly a "brutha" or two.

FWIW, looking in the furnace room if the basement is finished is a good start but I suggested the "tap tap thunk" as a secondary thing to try because it's easy enough to do. Problem is you can't always assume that all joists run in the same direction. At least in my house for example there's about a 4'x6' section in my living room where the builders all of a sudden changed directions perpendicular to the rest of them. It's actually a spot where I'd have wanted a tank if I wanted a tank on the main floor. Stellar, I know. I'm sure most houses are built with sanity but if I've learned ANYthing in life it's that you shouldn't assume people will have done things in a manner that makes sense to anyone but themselves. :)

Word. Er, I mean .. um .. Mang. Brutha! Fo shizzle or something.

TeeHee...

By the sounds of that there was probably a cantilever there. One of the reasons to switch joist directions.

I have built houses though that joist directions switch several times. Back in the day of limited spans of 2x10's it sometimes the only way to do things.
