Waterfall weirs for diy filters

[koiguy1969]

alright i have made 3 waterfall weirs..for those who are building stock tank filters or filters that with a flat surface for mounting... these are all made of 1/2" polyethylene structural foam just like the rubbermade stocktanks...
$25.00 each includes shipping....you will need a good silicone sealer and some stainless hardware for mounting
pic #1... inside weir dimensions about 9" wide and 9" L (out) side walls are 1&1/2" tapered to about 1/2" at edge...outside or mounting dimensions are 12" total heigth with bottom mount plate is about 3&1/2" ( sanded surface like mine)
pic #2 ...inside weir dimensions are 9" wide...6&1/4" L (out)... 1&1/2"side walls ... outside or mounting dimensions 13" wide X heigth 3" (sanded finish like mine)
pic #3 ...same as pic#1 but smooth finish
pic #4... shows back (mounting side) veiw..
P.M me if you have questions, i will give my cell # if you like and we can talk instead.(so much easier to ask and answer that way)

Very nicely done. That is perfect and you found a nitch. I have a friend that will be probably be buying one of these from you in the future.

Very nice. I needed this in the fall last year... I like the different lengths you have come up with.

Ya, I had to buy the plastic gun and material to make mine so this is a steel. It was a good learning experience for me, I just wish I had ordered the black HDPE not the white, but im sure will be green over time anyways...

pic#1 is gone... i have one available that is 13" wide (across ) and sets out just over 9" from mounting surface of filter....needs a mounting area of atleast 3" high by 16&1/4" wide..

I will be in the market for one of these very soon. Just haven't gotten my tank yet - still trying to decide on 100 gallon or 70 gallon.

 

[koiguy1969]

70 gal stock tanks are no longer manufactured by rubbermade but some stores still have them in stock...just let me know if you want a special size..go at least 100 gph flow per inch of weir width. this pic is 1200 gals on a 10" weir. the top stone removed to show weir and extension (extensions are not neccessarally needed)

nice

 

[koiguy1969]

they seem to do the job quite nicely, without a doubt...and your not gonna get a S.S one for anywhere near this price... i may be able to get them cheap because my uncle owns Quality Stainless Manufacturing... but ive never asked him.
