Thread: Epoxy options

Noi koi, my apologies, but I thought this would be a good place to ask.

I have a 3000l indoor tropical pond, wood frame and ply lined. It's been running just over 2 years now.

In summer I want to strip it back to the carcass and redo it with light blue epoxy instead of a liner, and install a viewing window. But I'm reading less than great things about epoxy pond paint!

What would be the best option for doing this and the best sealant for installing the window please?

The reason for the blue epoxy is mainly for the colour - many of my fish in there are dark and it's hard to really enjoy them - but also because I want to add a couple of features into the structure (shallow trough for growing houseplants where the fish can't eat them, built in step).

Being indoors it's not going to be so subject to changes in temperature; will that make any difference or should I look at including fibreglass in the epoxy?

I don't know much about sealing ponds with epoxy. I have heard scenarios where it hasn't stood the test of time, but I'm sure there's lots of ponds that are doing just fine with it.

If budget allows you could consider having it fibreglassed with a blue gel coat. Shouldn't be majorly expensive for a 3000 litre pond.
