That may work. It's says it holds up to heat and UV. I wonder if I can find something similar around here.Originally Posted by Frydaze1

"Stays strong in heat", doesn't mean that it is food grade or potable water (NSF 61) rated - all food grade plastic has to be white in the US. Of course, just because it is white doesn't mean that it is food grade! One thing you might consider is running water across a pane of glass that is painted black on the back(non-water side), or painting any of your plumbing or sumps with a dark paint. A thermo siphon is a great idea, but getting a heat exchanger to work without adding any metallic parts, unless stainless, is an interesting proposition. As with anything, start small, or you might find that you overheat your system, and end up having to cool it. Obviously, don't create any super hot water that flows directly into your fish tanks.
I'm working with a friend on getting a system started in West Los Angeles. Are you anywhere nearby?
And yet this tubing is the standard in hydroponic systems, which are primarily for growing food.
Really? Because the food grade 55 gallon barrels are often blue or green, aren't they?
I'm manually turning it on and off. It doesn't heat 450 gallons of water so quickly that it gets away from me.
Yes, I'm a little more than an hour away.
Strange, isn't it. Obviously it is fine for plants and possibly fish. It is not rated for potable water, which means it could contain certain chemicals that are dangerous to one's health. I'm not saying it does, but it could.And yet this tubing is the standard in hydroponic systems, which are primarily for growing food.
Oops, "food grade" means that the plastic is held to higher standards than normal - it doesn't have to be white, but often times is. If you want to see some legalese from the FDA orReally? Because the food grade 55 gallon barrels are often blue or green, aren't they?
Who writes that stuff!

So are you saying that vegetables grown hydroponically using standard hydroponic equipment aren't safe to eat? Or are you just telling me that since I'm using it I can no longer drink my fishtank water if I get the insane urge to do so?
