Plumbing

I'm building my sump and wanted some ideas from y'all! Its a 20 gallon high. Will have three compartments. Fuge will be the smallest because of availibility of space. I want the return bigger so my heater can fit in the space. The tape in bottom of tank shows where I was thinking of putting baffles. What ya think? I will have 2 returns whereas the skimmer section will get 3/4 of water from return and the fuge will get 1/2 water. Heres pic:

I thought I'd read one time to turn your return pump off for a 1/2 hour every day to give it a rest. Is this true or not?

Thanks in advance,

Okay, from that pic, the piping on left is the drain. All the fittings on the drain need to be tefloned, clamped and glued? And, on the right is intake from the sump. Pump on bootom right of pic. Does all this need to be clamped, teflon and or glued?

The weekend is coming soon and I will need to go ang get some supplies soon, so some quick questions.

1). VHO- I have 4 VHO's on the system. I need to by two ballast and the seller said he buys them from the builder store. (Home Depot, etc.) the question is: What can y'all tell me about VHO lighting. I never used then before? And, do y'all get ya lighting from HD or where? VHO parts, endcaps, etc.? Should I mount the ballast and such under in stand are on back of canopy, what ...

Ok, I have two PC's lights but they are not the 50/50's, two whites on one and two blues on the other. My question is: Would you put the blues in front of the tank or the whites?

Now protein skimmer question: are you suppose to have any bubbles coming out of the return at all? Also, I still don't have much foam in the cup so I turned it up a little last night, thus creating some bubbles out of the return.

Thanks for ya help in advance!
