2" or 3/4" Aqua UV???
Right now I have a 1" return line. The 3/4 would seem to work better. A 2" return seems far too large... although it could "slow flow" more in the UV housing I suppose...
Best bet is 3/4 right?
Thx
That is simply regarding the fitting on the in/output. The Actual sterilizer is the same. Are you putting this in-line with your return pump?
You say "stage 2". What exactly are you trying to accomplish?
Are you trying to reduce crypto? Crypto requires a zap count of 280,000 μWs/cm² to eradicate in a single pass. You're not going to get anywhere close to that without a massive UV. How many GPH is your return running?
What algae? on the glass?
