[Vlado4x4]

I want to modify my sump there´s to much detritus and i want to put a couple of bafles. Is there any silicon type of brand that i can use so i don´t drain the hole sump ? 80g sump !!

Wanted to use DAP aquarium silicone from Home Depot, but it dosen´t say if i can use it with water in ...

No such luck. To adhere properly both surfaces must be clean and dry.
