Polyueria vs. Fiberglass, which would you use?

Right Nancy, I meant Chai.

Chris, nice going! Several things I didn't know there. Big one is the business of using laminating resin without a sealer. That's one more method I can add to my list of things I can do to kill koi.

I agree steve, I don't like the lumps but that is just my personal opinion. My pond has neither coating, I used a liner. Next pond I hope to glass it!

Whichever I could get the better deal on...that is if I was using a contractor. For DIY (which is what I would typically do since I am a tight A$$), I'd still go with Sani Tred or CIM. I don't want the readers to think that either Fiberglass or Polyurea are superior or the other. They both offer different advantages and have different disadvantages.

Another note to add to your coment, is algae grows anywhere and everywhere. Diesel fuel tanks get algae, water in zero light gets algae.
If it is the right kind of algae I dunno, I am not a expert on that.

Depending on conditions, all ponds get various algaes. What I've seen is gelco ponds (only 2) that were so smooth that the algae couldn't adhere to the walls until the gelcoat aged to a point and then in patches that expanded yearly. It took several years for the first signs.

I've seen other ponds but didn't notice the walls and didn't know if gelco was applied or not.
