Ok thanks. That makes sense.
On a related topic, I am using all flat-black fittings and the AQ in-line G1/4 water temp fitting is not. Are other company's in-line water temp sensors "plug and play" with aquaero or do I have to use only yours. I guess I can tuck it out of the way.
Suggestions to product management: many vendors are moving in the direction of 4-5 colors for every fitting. They look great; not sure if they all sell well though.
Thank you for the continued advice.
