Hello- Thanks in advance for the help. Total newbee to spas. I just made a wood tub and am now doing the plumbing... Question is: Does the Ozonator have to connect to the 3/4 post heated water via an actual ozone venturi or can I just use a PVC T fitting where the 90degree entry goes to the 1/4" ozone tube. Basically, I'm just asking if I really need fancy venturi or if I can just make one with a 90degree angle instead? Thanks! Glad I found this forum. I'm about to jump into the world of water management with no clue what I'm doing
