I have several Turbo Twist UV lights and none of them have leaked, a couple of them have been in use for several years... I've also talked with a lot of UV users and have never heard of any of them having problems with Turbo Twists leaking...
I've seen and read about Aqua UV Units... but having never used one personally I have nothing to say for or against them... All I'll say is I've done a lot of UV research and have no reason to discourage using one...
Based on my experience with them... 1W per 10 gal is enough, therefore I would suggest a 13.5W or larger UV for your 135 Gal... I have a Danner 20W on my 125 gal... Thee is nothing wrong with a little overkill, but at some point overkill becomes excessive. I'll let you decide if 36 W is excessive overkill, as the only disadvantage will be the cost of bulb replacement and the very slight increase in electrical use.
The "max flow rates" listed on UV units is regarding the max flow the housing can handle before leaking... this rating has absolutely nothing to do with efficient performance.
Mos90... You stated you called Aqua and they recommended 10~20 for a sterilizer... 10~20 what (gph or gpm?)... and to achieve what (removing green water, killing bacteria, clarifying water, killing parasites, etc?)
As with all aquarium products, I encourage people to trust experienced user recommendations far above manufacturer recommendations. Simply put, users have nothing to gain from people following their suggestions, manufacturers very often have ulterior motives... Just like "up to XXX gallon tank" manufacturer recommendations on filters, I find manufacturer's ratings on UV lights inaccurate...
Aquaventions… As for your set up… I suggest you push approx 10 gph per W through your UV light… So 360 gph through a 36 W unit. I suggest you push the cleanest water you practically can through the UV unit…
Eheim confuses me with their rating systems. I never know if what I am reading is the max flow rate of the pump (like most brands use), their suggested actual flow rate (which is typically exaggerated) or some other number. In a quick search I found many different gph ratings for the Eheim 2028 ranging from 280 gph to 189 gph and I’m not willing to speculate as to which is which, nor do I know if any of them are actually true… Therefore I will not speculate to give you “the best” suggested arrangement…
