Moon's Graden

Hello Everyone,

        My name is Robert and I am a long time lurker, first time poster.  I never posted because
everyone I know said Ill get flamed or bombed.  Frankly Im a little nervous but here goes
nothing.
        Lately our web site has been getting deluged with questions about *** roofing
material.  Every one wants to know if it is fish safe or not.  For some people it has worked and for
others it has killed their fish.  I ask for everyone to please pay attention here because I will go into
detail why this is.
        Lets start with EPDM ***, seeing that most *** roofing material is made from
EPDM polymers.  EPDM stands for Ethylene Propylene Diene  Monomer.  While there are many
ways to formulate EPDM *** using EPDM polymer, they all share a basic structure that makes
it heat and air pollution resistant.  EPDM *** can be called EPDM *** as long it contains
EPDM polymer.  EPDM *** can be made using only a small percentage of EPDM polymer.  
This makes EPDM relatively inexpensive because it contains a little EPDM polymer and
inexpensive oils and fillers.
        In conclusion, that is why some *** is fish safe while others are not.  It all depends on
the process by which it was manufactured and what fillers and curing agents were added to the
***.  Not all EPDM is made with the same formula.
        The other *** is Butyl ***.  Butyl *** is more resistant to biological decay while
combining exceptional elasticity.  This type of *** is also used for waterproofing the roofs of
commercial buildings as well.  Now, given that EPDM polymer is resistant to heat and air
pollution while butyl *** is more resistant to biological decay while providing elasticity, the
two polymers can be combined to create a balance.  Butyl *** tends to be more expensive than
EPDM because it must be made using mostly expensive butyl polymer with very little filler.
        In closing, I want people to know that simply knowing if it is EPDM or butyl *** is
not enough.  Unless you know what fillers or curing compounds were used in the manufacturing
of the compound, please dont use the roofing material.
        I thank you all for your patience and if anyone would like to contact me, I would be more
than willing to attempt to answer any water gardening questions you may have.  I know this got a
little lengthy, but I truly hope it was helpful.

Thanks for the useful post.  Do you know about the comparative composition
of pond liners and roofing liners from the same manufacturer?

Thanks,
John.

never argue with an idiot, they bring you down to thier
level
and then beat you with experience

see my pond at:

not shure of this but i thinkd its accurate

if the origional poster is still around please help

Don't know for a fact, but I once heard it was actually the car dealers
wanting to create more of that "off road" feel while their customers drove
their nice new SUV to work and back on the highway everyday, and
under-inflated the tires on purpose to change the handling of the vehicle.  
The tires weren't rated to run at the lower pressure level, and ran hotter
then they were supposed to, thus the *** degraded.

With that said...  personally, I think it was the KH that caused them
to blow ;)

John.

come to think on it that would be one easy way to clean the
pond.
