Hey Ohm do you think you could put some directions up in your writeup for the tub setup? I can't tell you how many emails I get surrounding hole relation, size, and orientation. If you think 6 holes are needed, tell people why. What are the recommendations for hole orientation? How much space should between the top and bottom holes to prevent air stagnation? What size tub is recommended or not recommended?

These are just a few of the questions I usually get asked. If you could put together a pictorial of what you do and detailed instructions, you would own this tek for sure.

Just my two cents.
