Melev,
Sound
it's not the sound of the water going through the piping but the sound of the bigger bubble popping from the drain pipe thats in the sump. I think there are a few other current threads going on right now with the same problem. It's about an 1inch or so under water. I had an extra 45 elbow around so I put it on and it helped relieve most of the big popping problem. It now diverts the flow and makes smaller bubbles but still some lager ones that pop really loud. I think once I put a tee where the elbow is now on the down section to vent out the pressure it should be better. I hope this makes more sense.
Equal lines
I got most of the info from Delbeek and Sprungs Reef aquarium vol #3.
"one common mistake we often see with the installation of tee fittings occurs when an aquarist wants to split a return line into two streams to feed water to returns at opposite ends of the tank. In this case, the incoming line is fed into the branch of the tee and the outlets are on either end. this causes a great deal of backpressure and results in reduced flow out both ends. the correct way to do this is to take one line from the branch to one outlet and the rest of the water continues through the run to the other outlet. Valves are then used after the tee to control the flow out of each outlet"
with the chart my 1" tee "flow through run" is eaqual to 1.7 feet of 1" piping. But when you use the tee as a" flow through branch" it's equal to 6 feet of 1" piping. Thats a big differrance.
equivalent lenth of internal diameter pipe in feet.

Pump
The tank is almost a foot off the back wall. I will have full acess to the back from the left side. The current 40g tank thats there right now is going into this 90g tank. I'm taking the 40g down along with the 12g nano next to it. That and the stand is 36" tall so if I wanted to I fit right through the front.
lid
I'm not sure what where you are taking about putting the lid.
the main tank has a lid for the corner overflow. The sump top corners are euro braced with a large lip. Thanks for looking out though. THe only thing I might see doing is plugging up the old return/ drain lines in the sump. They are pretty high up so I'm not sure I need to yet. The whole sump will hold about an extra 6-8 gal before it hits the holes.

bigger and bigger
I know i know. I have a whole foot behind the tank that could of made it a 120-150g. I still live in an apartment and 90g with a 45g sump is still alot of water. I'm hoping not too much. So a 120 or a 150 was way out of the question. I would have loved too though. The good thing is I have all the equipment now to run a larger tank. So come house time be sure to look for a at least a 120 and up build.
