@ Scott:  Where do you get your plastic?

That was an interesting discussion about water hyacinth. I'm wondering along with Chris whether there might be a plant that acts in a similar way that is not invasive here. Oh, I see there's a thread up there ^ in the forums, so I'll head there next. :)

Re: a cover/raft...my thoughts are, plywood painted with marine paint. Marine paint is not exactly organic, but it's very practical, easy, and made for water. I think Lee has a good idea about fiberglass, too. You could also line it with pond liner, I suppose. I'm just going to work with PVC pontoons.

Paraffin and beeswax are clever ideas! I wouldn't be as concerned with melting temps as I would with softening temps, though. If it gets soft, it will get tacky and can be messy. Ideally it shouldn't reach the 112 degrees of summer, though.

I agree with Vlad about the aluminum. I personally would avoid it. It's been strongly suspected, though not proven, to be related to many diseases, including Alzheimer's. There's an on-going battle about its toxicity. I'm allergic to the alum in deodorants, so I'm more cautious of it than others might be though.

Larry CG - I called the plastic business I use and a 1/4"-4'x8' sheet ABS $65 and expanded PVC is $40.  Of course the thicker you go the more expensive it gets. I would say that price is not that bad.

This has nothing to do with the treatment of the fish, but I watched videos of a gentleman in Costa Rica.  According to him he did not feed his fish for 1 month trying to get his nitrate levels down.  They may not have been happy, but they evidently survived.

@David Schwinghamer - When I researched how to humanly kill fish I came across a study and rules laid for out commercial fisheries by some organization that determines inhuman treatment of fish.  As I recall the figure was 72 hours.  But that of course must change depending on the seasonal temperature.  Currently with temperatures as high as they are, I'd guess that figure is about right.

Can you please comment above in the need help discussion so your answer doesnt get lost in the forum jungle?

I think my blue tilapia just hate other colors of fish, had one more fish death today, the last red one, and none of the blues have died, and there is one white/ barely red colored one left and hes the biggest i think thats why he's surviving.
