    Well Jim, help me out here and tell me which product you would go with. Should I go with roofing liner (seems as if it is a big secret as to whether it has ever even been tested or not) or actual pond liner which is "approved". My gut feeling is that responses from manufacturers reps took into consideration possible legal ramifications and it is quite possible the roofing materials were never tested therefore they did not pass or fail anything. I realize the costs associated with testing are exorbitant and must be passed to the consumer. Perhaps this is why there exists such a significant price difference between pond liner and roofing liner??? You really gotta wonder. Id like to save a few hundred dollars but don't want to end up with CPs that look like something out of a B rated horror flick if there is actually some sort of a difference between the two products.

    Well I can't vouch for the roofing product but if MANY people have used them without ill effects on their pond inhabitants then I can't see a reason why it would pose a problem for CPs.

    Now if your plants do turn out to look like B rated horror flick.. I will point to the other guy and say HE DID IT!

    Ha ha ha! Too funny. I am actually leaning towrd the .60 roofing liner right now. Good thing you commented that you couldn't "see a reason why it would pose a problem for CPs". I needed an expert opinion on this to rationalize pocketing the difference in the price of the liners.

    How do I save a thread so that I can refer to it again in say... 3 to 5 years if my plants should start glowing by the light of the silvery moon?

    Seems to me they have been tested: you've mentioned how you're using them for Koi. I couldn't imagine CP to be any more sensitive than Koi. I have a small Koi pond in my own yard -- it is an old spa/hot tub converted to Koi pond.

    I made a purchase from pondliners.com of a 10x10 and the shipping was marginal. I think total I paid about $32 for liner and shipping.

    Yes Pingman, they have been tested by me and my neighbors on fish and aquatic plants. For some reason I keep thinking CPs will be considerably more susceptible to chemicals leaching. Don't ask me where I came up with that.

    I'm going for the roofing liner.
    a 25x50' "approved .60 pond liner at pondliners.com is listed as this-
    25' x 50' $612.50 538 lbs
    shipping is going to be somewhere around $200 because it is over 500lbs.

    A roofing liner from Firestone, Georgia Pacific, or Johns Manville in the 25' x 50' at .60 is going to cost me around $490 (includes tax) however as the supplier is local, I incur a delivery charge of $25 plus a fuel charge of $5 as opposed to a $200 shipping charge. Another added bonus is that the drivers move the liner from the truck to the site. The .45 pond liners were more affordable and the shipping on them was only around $100. Over all, I save about $300 and I get a thicker liner that is more capable of withstanding roots of surrounding vegetation.

    Oh my gosh, my el cheapo side is emerging as I am going for the roofing liner! Time to start pricing geotextiles for the sides.

    Right click on the topic and save to favrites / add bookmark should do it. I know what you mean. I had pictures saved as PM's and to my surprise and dismay...

    I know you know me well enough to know I was teasing poor Tony. I don't want to save this thread but there is a thread I want to save that has germination information in it that I better bump so I don't lose it as it is coming close to the 30 days where it goes into the Terra black hole. I already lost 4 private messages that I saved that had CP growing information that I THOUGHT I was saving and presto whamo all gone when I went to print off my instructions. I about had a heart attack. Come to think of it, I ordered a ping for next spring and I need the information on potting and soil medium that pingman provided for me in a thread so I better bump that before I lose it.

    Jim, I tried to right click but all it is doing is saving the web page in my Internet Explorer "My Favorites". I don't think they archive these threads for ever.
