DIY filter waterfall outlets

So are you guys mainly using a heatgun which I do not own, or are you using boiling water and molding the spout? Id like to do this on the spout coming outta my bio filter iv made, I like the look and the water spread.

 

I used a heat gun..$10.00 at Harbor Freight.. but people say boiling water works well.

 

Thanks, I think im just going to buy the heatgun probably need it in the future anyway. All the joys of being a home owner!

 

a pipe out fall to pond from filter elements .. thats what my waterfalls are , not so pretty but..

 

I did something similar with my waterfall.. my filter/garbage can filters water vertically and I put 2 pipe fittings coming out the top and attached a T connection to one and the other comes straight out.: I used 2 flexible pipes to go to left and right side of falls and straight one provides the middle flow all are hidden in the rocks.
