Never mind the idea of drilling - it would mess up the shape of the pump chamber too much and probably crack through the body.
I did some testing at 5ft head height though:
3/4" tubing with 3/4" barb: 2g in 0:50 = 144gph
1/2" tubing with 1/2" barb: 2g in 1:23 = 87gph
My head height will be more like 4ft and since I was hoping for about 200gph I think it'll be just about right.

Finally, somebody that gets it. I have asked this question 20 times... And nobody has the brain in their head to understand the "head" of a pump for a verticle 4ft UV. Sicce didnt respond to emails and Chad at BRS was willing to sell me a Sicce 0.5 (with only 2ft of head!) To run a verticle mounted Pentair 40 W 6ft over the top of my tank from my sump. I posted on AskBRStv... They didnt post my question. Seems shady. Making a lot of money on people burning these units out - hence the bad reviews. I asked on this forum 3 times - and nobody responded. So much for the reefing "community". Thanks for an intelligent post. VERY helpful.

The pump is fantastic - dead quiet after break in and after I realized that something about my sump return chamber was amplifying sound - wrapping it in a silicon pad fixed that.
The 2.0 is considerably more capable of handling head pressure. Sicce is great in that they post the head/flow right on the box and on the product web pages.

Thanks man. I saw the specs with a graph on BRS - but the graph was numbered wierd and was using commas for decimals which completely threw me off. Once I figured out that the comma was a Brittish decimal - the smoke cleared and the graph made sense.

Yes, you are 100% correct. - the 2.0 is what I think is best.

I have a 1.5 already that Onuse for Carbon amd GFO that I'm gonna use until I order a 2.0 next week.

Have the Pentair 40 W and the pumping pieces on the way. Thanks. Honestly, I would have been another one of those fools putting a bad review that burnt their unit out - thinking it was Pentair - when ustomer service at BRS tells you a 0.5 is OK to use. Let me tell you, they got an email from me that called them out on this, their crappy coral packs for WWC, and that I've been waiting over 2 weeks for a shipment of Chemiclean for a cyano outbreak. Man, BRS has jacked up 4 of my last 5 orders somehow. I'm counting this one too because that Sicce .5 would have burnt out my $400 UV within a few months. They need to hire competant people to answer questions. Anyhow, thank you. Wouldnt have figured it out without the help. Thanks man.
