It looks like you used 4" for the body. I think I will try the 3" clear and make the body longer. I will have plenty of clearance in my planned stand. I will shoot for about a quart of capacity. Thanks.
Thanks for the information SpottedDog. I am beginning to accumulate pieces for a 15 gallon conical build. I was thinking of using a clear PVC for the body of the yeast/scrub catcher. What is the diameter on the body of the catcher for the 15 gallon? I found 1 ft of 2" clear PVC for $12 plus...
