Backyard Aquaponics
A place to discuss aquaponics

Hey guys, I'm going to mold a tapered drain into the RFF im building, to make the waste drain easier.

I've heard 'black waterfall' or something like that is fish safe but I can't find it local..

I've also heard most of the others use arsenic in their construction. So.. dont really want to use them.

Has anyone used some before?

I could always coat it with pure silicone to proof it but I would still worry about the arsenic content if the silicone wasn't a perfect seal..

Thanks guys!
Trent

Try this or similar. This one says fish safe. There are others available too. I searched pond foam and got several hits.

How strange! I never got the notification of a reply. So sorry I never replied. Thank you

Thank you, I found this one by aquatec


Hopefully this sticks ok to the plastic drum!

I will post a picture in my system thread if it does work
