LF Sump

[Grenade Glass]

I was setting up my new 90 reef late last night, and was trying to fix a leaky bulkhead for return pump and cracked the side panel of glass on the sump. does anyone have a old sump laying around? shoot me a pm!

I have a 120 plumbed for an external return. $150

would be great except the 90 gal stand would never fit that.

Petco is having the dollar per gallon sale on glass tanks. Might be a cheap sump if you want to build it for your needs.

you might want to consider replacing the glass on the broken side. glass is cheap and it isn't as much effort as it might seem on the surface.

I did the same thing on my 40 breeder. new glass, RTV108 silicone:

and evidence that it holds water http://www.reefcentral.com/forums/showpost.php?p=17008978&postcount=79

ended up making my own sump:

Got a 29 gal from petco, and some 1/4" plexi glass which i used to make baffles huge improvement over my broken sump

Ha! That's awesome! Nice work!

some people say using acrylic on glass is not a good idea,bulkheads may blow out..I'd do some pressure tests on it before using..

Do you mean the baffles might blow out todd? I dont see any bulkheads.

It will most likely hold but wont be 100% water tight because silicone doesnt adhere completely to acrylic. But with a standard flowrate going through the sump it probably wont matter

yup thats it lol wrong wording..I remember when I was searching for info on building my sump,I ran across many people that said use glass on glass and acrylic on acrylic or its a good chance of bond not holding well..

I'm sure it will be ok if you keep the chambers pretty much filled equal at all times,but I would not trust that myself

I built my sump using a 29G tank and 1/4" acrylic baffles. It has been up for about 3 months now and seems to be holding out just fine. The baffles on either side of the return chamber have a slight bow to them (1/8" at the top center). This started within the first few days of running and doesn't seem to have gotten any worse. I think if I were to do it again that I'd use glass. Not because I think the acrylic will fail but the bowing looks like sloppy workmanship and more water flows over the middle of the baffle than at the edges.
