Are these food grade? In other words, can I use them for hydro and aquaponics... or are my fish going to die and my food be poisoned? :-)

I do not know if you can use hydro and aquaponics... or if they are food grade. I used them to storage files and clothing.

I would go to a foodie website and ask and/or purchase containers made especially for food. Ie ACF or CIA. It is not advertised for food and there is probably the answer.

I can't answer that definitively, but I would only put fish in it during a tank cleaning, not for any longer than that. As for food, I would feel comfortable putting packaged items into it, but not just placing food directly into it. Like I said, I have no knowledge of the chemicals, etc. I'm just giving my opinion. I only use them for clothes and documents, so that has not been a concern of mine. I'm sorry I can't offer you any direction!

Sure, if they've been boiled for awhile. Seems kind of rough on your motor, if they were not boiled enough to be kind of soft. (you are making pet food, aren't you?)

Unfortunately most of the water barrels like this one (with the hose for watering) are not food grade. You can get food grade water storage containers, but I couldn't find one built with the water hose at the bottom. I use it for watering the garden anyway, because I couldn't find a "pure" one to do so.

Yes, this is 100% food grade silicone but it is not 100% silicone. Please read FAQ for an explanation by the manufacturer of our silicone products. Sorry for answering your question late. I just came back from vacation and I did not have access to my computer while I was away.

The label suggested hand washing but don't worry, the clean-up so easily, it's almost a pleasure. You don't want to crack the ceramic coating from the changes in temperature that a dishwasher goes through, it'll effect the non-stick quality and expose your food to the underlying metal. That might not be a nutritional issue...but, if your using these to avoid excess exposure to environmental toxins, why even take the risk?

This is NOT food grade tubing. The description states "Not for use with ice makers" which actually indicates it can't handle pressures over about 30 psi. But if it was food grade tubing it would specifically say so. Clear food grade tubing will be made of a denser material which helps prevent bacteria from attaching to the sidewalls. For this reason food grade tubing is usually significantly more expensive. And you need to be careful because there are sellers here at Amazon claiming their tubing is food grade which is not actually food grade. If you see in the description that the tubing conforms to FDA, USDA and 3-A milk handling standards it's a safe bet it's true food grade. Anyone making that claim falsely is subject to prosecution and being buried in lawsuits. If you're looking for water line, as most people are, do a search for "Pex Ice Maker" and you'll find kits with various lengths of line as well as the ends you need to attach to ice makers. Pex line is for use with potable water and can handle the pressure of a water line. You can also use copper which will last nigh forever but it requires a double flaring tool to install.

Is this product, or any other phosphate supplements on amazon, safe for aquaponics?

Nope. Water will destroy these. I had these above an aquarium. The little splashes of water caused these to corrode and fail. There are water proof versions of these. I use those now.

I use them for that purpose too, but it depends on the requirements of the plant. Look up the recommended balance of nutrients and if they are in line with with a 4-4-4 plant food then they will work.

They hold up well with 5 and 7 years olds and would most likely do well in an aquarium. I would be careful because they are from China and you need to make sure that something in them would not be harmful to the fish.

Hi Raymond, I wish I could help you but I haven't used mine yet. I intend to get back to bass fishing sometime, but I'm basically a fly fishermen and I'm having a hard time putting my mind back into spinning gear mode. Yes, they sound good, and I hope someone can offer you a definitive answer soon. Tight lines! Regards, Ron

no, these are food grade / have had no problems at all. I would still boil and filter after sitting a long while anyway. as you fill, pour a couple caps of Bleach in with it

So sorry, I can not help you on this. I would call a local nursery and ask them or contact the manufacturer. The water from my urns using this product is for watering plants - don't know how safe it would be for fish and don't think I would use it until you find out if it is safe for them. Wish I could be more helpful.

I can't read what the box says either. However with my experience working with them I can say they are similar to other paint pens out there. I would say they are water base, the paint dries fairly quickly and does wash off with water. As for if they are non toxic or not I can't say (since I can't read what it says) but to be safe I would avoid eating them. Hope this is some help.

They are food grade, no problem there at all. Been using them for years and so has a friend. IDK re yorkshire pudding. Read the specs online, not sure 100% re how much heat they can withstand.

If they are not used and sit on the self they maintain the high pH. Once the seed germinates the pH level slowly decreases. The pH stays high easily past the point where the roots push through the bottom of the block. And yes, very good for Aquaponics systems.
