I contest that it's a 32 gallon brute. ;)

Some good progress.

I contest your contesting. I've got 8 5g jugs dumped in there, baby!
 
Sump Check

Sump Check

BEfore I build the sump tomorrow, I've put together a design and a cut list/diagram. Did I miss anything?

Any suggestions?
 
Looks good to me. More and more having two different return pumps seems like a really good idea. I would be a little worried about having the return plumbing going all the way to the bottom of the tank, but as long as you incorporate good siphon breaks that can not possibly fail, you should be ok.

Looks fine to me. What is the spacing between your baffles (have I asked this yet?)?

I was going to make thm at 1" or 1.5".
 
How thick is the acrylic you are using. (is it acrylic?)

I also don't see why you have a top piece, unless you are using the top as a single piece eurobrace, or something like that. The top will be open right?
 
Yes, what thickness is the acrylic? Half inch? If it is quarter inch, the end pieces and baffles are all 23.5" wide.

You don't need two baffles after the refugium.

I would suggest you keep the sump at 16" tall instead of 18" tall, since this is only a 120g reef. Take away the bottom and top pieces, and the walls are only going to need to be 15.5" tall.

Split the return and refugium zones equally.
 
Yes. It's 1/4" acrylic, but I was going to route of the edges. Perhaps not though.

Yes the top is for a euro brace. I am going to use the scrap from the inside to make a top down box.
 
Got all ofthe pieces cut. We will e sanding them down a little bit and gluing tomorrow. Any advice on that step? How close to exct square do the pieces need to be, and how much does the Weld On 4 melt the plastic? Will it help to even out inconsistencies of maybe 1/64' along the side of a piece? Is there any way to put too much weight on a piece as it sets , and put things out of alignment?
 
I'm also looking for a small 4 bulb T5 fixture to hang over the frag tank. Any suggestions? I don't have a ton of money to spend on it right now... Maybe $200ish.

I've very much enjoyed them wide enough to put your hand down to the bottom, and for me that's about 2". It makes maintenance a lot easier.

I don't know if you've been reading the DIY acrylics section of my site yet. I may be repeating stuff you've already read.

The pieces should be very square, and when you sand down those burrs on the acrylic, avoid rounding over those edges. It would be better to scrape the edge with a utility knife razor blade held perpendicular to the acrylic, scraping it smooth.

#3 and #4 melt it equally. #4 takes a little longer to set, that's all.

If you put too much weight, you can press the solvent and melted acrylic right out of the two pieces meeting, creating a dry joint. It should be just enough, but not too much.

It doesn't fill in holes at all. The material must match up.

Using speed squares, double-check your work as you proceed. This keeps things square.

Practice with scrap so you can get a feel for how it works.
 
I will most likely use the razor blade, as you have mentioned on your site. I was worreid about creating uneven edges with it. I think I may try to clamp each piece against a straight metal edge so that I cant get too deep. Is that a decent idea?
