Plumbing questions

Well i have a single 1" drain now and i have to cut back the flow

 

Interesting development, I was comparing my new bulkheads to that of my center 'drain' on my 40 and realized, these aren't the same size. At some point, I completely forgot that my center drain hole was 1.5", not 1". Now, that doesn't really matter for my 40, but for the 65, are two 1" drains still sufficient? Adam seemed pretty confident but thats when I told him that I had a 1" drain now. Not sure if that would change anything.

Certainly makes me realize how my PVC will be lighter /DesktopModules/ActiveForums/themes/_default//emoticons/smile.gif

 

New question! /DesktopModules/ActiveForums/themes/_default//emoticons/smile.gif RC calculator says a 1" drain will get about 600gph. The mag 7 is suppose to get 700 gph. I have a strong feeling the guards I use on my drains must be cutting this down a lot seeing as my mag 7 has to be cut back with the valve otherwise it overflows my main tank. Soo... with that in mind, I will eventually have 2 1" drains. If anyone has any other drain guard suggestions so fish don't get sent to my sump, I would love to hear them. Otherwise, when I have two 1" drain pipes coming together, at most, that would be a theoretical 1200gph going through the uniting pipe into my sump. RC says that 1200gph flow needs a 1.43" pipe diameter. Should I use couplings and increase my pipe lengths to 1.5" where they join up and enter my sump? Or should I go smaller than that?

Sorry if none of that makes sense.. /DesktopModules/ActiveForums/themes/_default//emoticons/smile.gif

 

That works. Thanks for the tip /DesktopModules/ActiveForums/themes/_default//emoticons/smile.gif

 

I think i am going to join them in an attempt to take up less space in my sump. Would using the special 1x1x1.5" T work best or if I could find a wyethat did the same change?
