I have a poly tank that is seeping (water) from a couple of places near

Was wondering if anyone could suggest a non-toxic material that could be
stirred into the water (maybe a clay material of some sort?)that might
stop the seepage?

TIA for any suggestions.......

Seeping or condensing? *This time of year, condensation is a problem
in a lot of areas. *Only insulation can help with that.

For leaks, polyethylene is kind of nasty stuff to try to patch with
anything sticky because not much sticks to it. *If you can't see holes
or cracks, not much point in it, either. *Anything like radiator stop-
leak needs heat to set it up and it isn't non-toxic.

HF sells a couple of plastic welding kits, if you DO drain and remove
the tank so you can see holes and cracks. *Uses hot air to do the
job. *I've done that job with a big soldering iron and some spare
plastic film, wasn't pretty when I got done but the crack didn't
leak. *Very stinky and kind of messed up the iron's tip until I could
clean it off with a file.

Thanks to all for your help. *Now that you mention it, condensation is
certainly possible as the water used to fill it (recently, for the first
time) was colder than ambient. *The "seepage" looks pretty localized
however and some is around a banjo fitting on the bottom. *OTOH, it
appears the volume of water under the tank (you can see it from the open
top thru the poly) has not increased since yesterday so maybe the
source, whatever it is, has stopped. *The suggestion of bentonite sounds
worth trying if required. *If that fails I guess I'll have to drain the
tank and try JB weld or heat welding if I can find the crack(s).

Thanks again guys - this is a great news group IMO (if one can get by
the dreary political and other OT BS that plagues it).
