Question container water garden help needed

Hi All, I am needing to seal the inside of a very large clay pot that I'm using for my water garden so that it does not seep. Can you recommed a product that is non-toxic to fish & plants? (Hopefully something I can purchase at Lowe's or Home Depot.) ALSO - There is a drain hole in the bottom that I need to plug up, but a recommended plumbers putty did not work. What else can I use to plug it up? Thank you for any advise you can give.

Hi Karenoke,

There aren't too many options for sealing an aquarium, or fish inhabiting environment. What you are looking for is a two part epoxy for potable drinking water. To make your search easier, the one that I use with great success is West Systems 2-part epoxy. (this is not an ad!) I have made several rock/cave backgrounds for my aquariums and this is the only seal suited for fish aquariums in my area. You can go to a marine store and ask what they use as well, a lot of them use fiberglass which can be a pain to deal with. But call the manufacturer and ask if they stand behind there product with fish involved. I get mine at Hardware Sales, but there is an online website ( that will list for you all there dealers.

As for the whole, you will need to find something to fill it with before sealing that. A bulkhead? and then putty? Make sure to use the epoxy over that fix as well, it is very strong stuff and will hold it inplace. Just a filler for a large whole won't be sufficient. Good luck.....
