Questions - Need some input

So I need some help on deciding what size pipe I am going to use for my over flow into my fuge. I have a 1400 gph return pump. Any help would be great. Happy reefing.

Hi all, I had an infestation of flat worms and after treating the tank for those I now have a significant algae bloom. It has been over a month now and I have done two large water changes and all of my water tests are at good levels. but I have a lot of red and green algae and even some of the brown algae on the sand bed.
Any idea of what is going on? or what I can test for? My skimmer is working well, I am not sure what is going on.

Building my 20 gal long sump from vague plans found on the internet and answered questions from here. Thanks Melev. I am about ready to plumb and saw the writing about drilling two holes in the return line to create a siphon break in case of power outage. Where exactly does that go? I thought it said about X inches below the water line but that doesn't make sense to me. Please answer and explain. Thx

So, Here's to asking the Million Dollar Question..... How does one balance the entire setup to eliminate the slurping sound the Weir box Makes...

In recap, 120 Gallon tank, the Sump is modeled after a Model F from marc's designs out of a 29 gallon aquarium (overflow splits to 2 sections, 1st being where the skimmer will sit and the 3rd section where the fuge is.) BTW, the Ball valve is located above the fuge....I could leave this one open and cut in a new Ball valve right over ...

A few months ago I got a Sea Hare to help with cleanup duties... After 2 weeks it died... My wife loved the little guy and looked for it every day... I have learned they can be difficult to keep, with a very high death rate... I have researched the web and can't find any good info on how to keep it living other than good water quality and that is still no guarantee of success... Any insight would be helpful... Thanks
