Forgot to mention... make sure that when you plan out your sump, make sure that you leave a lot of room for the main return pump. That's the first compartment that will drain, so if it's on the small side, and you don't have an auto top-off unit, you'll run into problems with running the pump dry.

The bubble traps only need to be wide enough to get a sponge in there to clean it out. I like about an inch wide... but others would suggest different widths as well.

Next sump I make will be out of acrylic with an external pump & built in auto-top off unit... along with a fuge as well. 8) I first need to upgrade my 4' tank to a 6' so that I can fit all the stuff underneath!

Great looking sump! I have a question on the baffles. Could the baffles be cut from acrylic or plexiglass, and then siliconed into a glass tank?

do acrylic, plexi will yellow and become brittle with age...

my question has to do with the "t" sectiono and ball valve from your return pump into the fuge area... what purpose does that fill? Just brining it back to the sump due to having a beefy pump?

I was thinking of doing something close to this but have the overflow dump site, baffle, Protein skmmer area, bubble trap section, fuge, baffle return...

My overflow is 2x 1" pipes, with a mag 9.5 I put a ball joint on both the pump return and one of the overflows... i can always adjust the pvc and put in the "t" and ballvalve.

TIA

If I use acrylic, will silicone hold it in place? Or would I need some other sealant, for bonding acrylic to glass?

you should be able to use the DAP silicone that he used in his project, or another marine safe acrylic bonding agent....

I'd get someone else to answer that for sure...

The "T" section is there to feed the fuge area. Since the fuge baffle is the highest, water has to be pumped in there, and then gravity just brings the water back down into the pump area. This way, I can control how much water flow goes to my fuge. The pump can handle everything.

Just make sure to do the middle part of the baffle first. That's the one that needs the most strength since it's up in the air. The other two on the sides can just be sealed on one side alone, and then as far as your hand can reach on the other. Those just need to be strong enough not to bend back and forth since they're sitting directly on the bottom.

Nothing can really bond acrylic to glass. All you can really do is to use a lot of silicone to keep the acrylic from moving. Just know that you might have to empty the sump every few months or so to reapply new silicone.

I've wanted to try to make some kind of auxiliary support system for acrylic baffles... like some pieces of small wood or plastic or something that will keep the baffles upright and spaced apart. Think of it like some of the old metal ice cube trays. They used to have a plain water pan, and then a grid that you stuck in to separate the cubes. If you could do that to the sump in some way, you wouldn't really need to smother the baffles in so much silicone. Just some inspiration if someone wants to try something like this.

What about designing small supports for the acrylic out of fairly thick glass?

sorry for the noob comment....but i see 4 compartments and you only describ 3. If the fuge is the far right compartment, what is the one with the LR rubble in it at the far left? Just a smidge confused about that.
