Fuge baffle - teeth or no teeth?

[thbrewst]

I had been planning to cut teeth into my baffle since Melevsreef does it that way. But after reading some other posts/boards it seems that some folks are of the opinion that they are useless.

Before I do all of the extra work of cutting teeth, what are folks thoughts? Teeth or Toothless?

Thanks

Depends on how your fuge is set up. Every situation is different. Tell us or maybe even post a few photos so we have an idea of what you are dealing with.

Not set-up yet. But the plan is for a 40g Breeder, 3 sections, laid out like;

Drain/skimmer -> Return <- Refugium

The idea would be to have the standard 3 baffle micro bubble preventer between the sump and return with 10" baffles (so the raised one will be at 11"). Then a 13.5" baffle separating the fuge from the return. That is the one I am wondering if I need teeth cut in or not.

Does that help?

Help with what?

Keep macroalges in the refugium? YUP
Prevent microbubbles? NOPE

instead of the teeth i actually just drilled 3 rows of holes....i think 1/8" bit.....it does help slow down the flow a bit for the fuge section....im assuming your using acrylic baffles....and mine is set up a bit different....mine is ......in that order if you looking at it....seems to work

Do no teeth then cut a bit of eggcrate that you can glue on if you want.

Ah, not a bad idea. I think I have some height to work with anyway.

Many thanks.

That's my plan anyways.

Really, if you have so much flow that macro is jumping out of the fuge, you probably have too much flow...

^^ definitely (for a refugium)




I routed teeth in my sump when I set it up.. but I built it too high and ended up breaking them off in order to lower the flow coming out of the drainage area..


I planned on building a sump similar to what you're describing but in the end, I'm going to do a separate refugium and have it drain directly into the return section

 

[thbrewst]

So, as a separate question, how much flow is enough/too much for a refugium? how do you know when you cross the line?

 

[weaglereefer]

Enough, when the macro grows and the nutrients are in check. Too much, when it's splashing and making bubbles in the return section.

I actually found that taking a piece of PVC and then grinding or cutting out a gap so that you can place it over the baffle works best. It keeps all the bubbles along the side of the glass... I've never had a problem with it.

I've got mine draining from it's separate box, down into the sump by a 1.5" bulkhead..

I open the valve enough so that water only makes it half to three quarters of the way up the bulkhead.. (which acts as an open weir)..

? cut the gap out and place it over the edge of the baffle ?

to "round the transition"

Yup. Like right now, I have a 3/4 inch piece of PVC taht I used a grinder to cut out a 1/4 gap to go over the baffle.
