Waterfall weirs for diy filters

[Aaron Rousseau]

Hi Koiguy,

Thank you for making a custom weir for me so fast (Aaron in Oregon)!

I'm thinking that I'd like to hide all spillway plastic with flagstone so I'm thinking about cutting down on the spillway length. So what do you recommend: reciprocating saw or would a circular table saw do it? I have no experience cutting HDPE plastics and can easily imagine that a circular saw might generate too much heat; thereby melting the plastic (and messing up a saw blade). I'm imagining using a drill and reciprocating saw to cut the slot on my Rubbermaid stock tank...

Thanks in advance for the advice!

i just used a utility knife to cut my tank slot. scored it along a straight edge, then just heated (softened) the tank with a heat gun. utility knife worked great. a recipricating saw should cut the weir just fine i would think. i left the extra couple inches on cuz you can always cut some off. better than being shorter than you need.

Pretty cool.. The Chattanooga Tennessee Zoo will soon be using one of my weirs in an exhibit there.

Koiguy1969 hasn't posted in several years. Don't think he is still on forum. This thread is 10 years old.

Is anyone in the USA making anything like this anymore, out of any material, for use with stock tanks?

IDK, but have you done a Google search? Maybe try KOIPHEN.com. Old thread and last post from 2 years ago was never answered.

@koiguy you still here? I think not as when I typed his name it did not link up like it should if he was still a member.

He is still on Facebook tho cuz he's on as a friend of mine. You could go there and message him https://www.facebook.com/mark.koiguy.castleberry2

Here is a photo of the kind he makes and he can make them to the size and shape you like, that is if he's still doing them.
