Baffles in sump leaking

I placed my sump baffles using silicone yesterday, and when I did a water test today, there were MULTIPLE small leaks in the baffles. Should I scrape off the silicone and redo the whole thing, or do small leaks not matter in the end? I mean, water is going to be flowing from compartment to compartment anyway, so maybe it doesn't matter if there are some small leaks.

I'm a newbie when it comes to stuff like this, so instead of just doing what "sounds" right, I thought I'd see if anyone has any experience on this. Will the small leaks grow over time, eventually causing the baffles to displace? Or is it alright?

 

ran into the same problem with mine. Ideally if u want a nice seal scraping some off is best. but i just over did it on the areas where it leaked. Make sure theres a solid bond between the glass and baffle, because silicone doesn't really stick to itself once cured.

just be very generous when applying it. lol my fuge is crappy looking, but it hold water.

 

Uhh... Silicone sticks to silicon. Silicon may be the only thing that sticks to silicon.

 

ive had other experiences. im sure it will, but with the pressure of the water in the sump acting against it, the best one could do is get a solid bond between the glass and baffle rather than bonding to the silicon and the glass.

 

I thought you were suppose to wait 48 hours to let the silicone fully dry.

 

I read that it could be water tested in 12 hours, but shouldn't be used in a system that will have fish in it for at least 48. I tested it with tap water, and emptied it out afterwards.

Thanks for the answers guys. I'll try adding more silicone to the problem areas, and if it sticks, great. If not, I think I'll just keep it the way it is unless the leaks get worse, because I really don't want to redo it if I can avoid it.

 

I wouldn't worry about it. Mine did the same thing, it's been in use for 2 years with no problems. BTW Did you use glass or acrylic for the baffles? And is the container glass or acrylic?

 

Glass container, acrylic baffles. I know the silicone won't bond great with the acrylic, but it still works well as a "wedge" of sorts. They feel very stable, so I think it'll be alright. Thanks everyone for the input!

 

I did the same also haha. I used tons of silicone. I only have 2 sections in my sump( no fuge) so I figure if they do fail, it shouldn't be to big a catastrophe. haha

 

I don't think a couple small leaks are anything to worry about. With the water flow that is going to be going through the sump I can't imagine those leaks are going to affect anything.
