Sump Build Question

yes...I use 3/4 " to 1" this is because this design works like a trap to bubbles and other small particles but yet still allows full flow of water without any backpressure. any smaller can cause problems and make it actully give you more micro bubbles. if its much larger its not as efficient as a trap. good luck hope this helps.

ditto... 1"
I read somewhere about making the first gap larger with a eggcrate shelf so that you could lay bags of charcoal or anything else you wanted and that would put it in the flow. I thought that this was a pretty neat trick. Has anyone tried this?
yeah I tried it with poor results..I found that a) the charcoal bags just became nitrate pools. b) that water will just begin to flow around them and you get to much bypass....If you want to use charcoal effectivly I suggest a canister filter or something of the like...thats designed to force water through it.....of course this is just my opinon and Im sure others will be different.
What I did was put the middle baffle in, then I marked the glass with a scripto pen where the silicon is going to be. I then ran a line of silicon along the line, I placed the baffle into the silicon. I used a long thin piece of pvc to smooth the silicon against the baffle. I then siliconed the outside of the baffle. I did the same for the other side. It worked pretty good.

here is my idea for my new sump. the refugium is on the other side so i can control the water flow into it. there will be a float switch on top of the return for adding cal and alk daily

I cut two small peices of acrylic that are 1" tall and about 2" wide. I then silicon them to the glass where my baffles will be. It creates a brace for the middle baffle so it can never fall and allows for easy drying and spaces the end baffles perfectly.
I run three baffles. One over, one under and one over. The center baffle sits right in the middle of the brace so their is 1" on either side of it. If you are only doing two baffles with 1", you could do a 1" x 1" piece maybe adding on a little to the width. If you wanted to fit three baffles in 3/4" it would be 1.5" x 0.75".
Cameron I picture it now. Here is my plan. Let me know if you see a flaw.
1st Compartment drain pvc and skimmer. I will do an over under over.
2nd compartment will have sand and macro etc (fuge). Then an over under.
3rd compartment will be the return pump.

Personally, I think you only need one divider and no baffle between the 1st to 2nd compartment. Trapping bubbles isn't a big deal there and most microbubbles will pop just from going over the divider and none will likely make it through the fuge and through the next baffle. I think you only need one baffle between the fuge and return sections.
