jcasisa Posted December 16, 2015 Share Posted December 16, 2015 Hello all, Question, I drilled the holes for my Synergy overflow box and did a leak test with the return pump into the display tank. I noticed that there was moisture on the bottom outside of the overflow box between the tank and the overflow. My question is, does anyone use any lubricant or sealant around the drilled hole to make a better seal? I was careful not to over tighten against the seals but I may have to tighten the nuts a bit more. I will be adding picture to my tank build this weekend. -John Quote Link to comment Share on other sites More sharing options...

FarmerTy Posted December 16, 2015 Share Posted December 16, 2015 100% pure silicone usually does the trick. You can get a small tube at Home Depot for $3. Quote Link to comment Share on other sites More sharing options...
mFrame Posted December 16, 2015 Share Posted December 16, 2015 100% pure silicone usually does the trick. You can get a small tube at Home Depot for $3. Make sure it's pure and does not contain a mildewcide. Quote Link to comment Share on other sites More sharing options...
jcasisa Posted December 17, 2015 Author Share Posted December 17, 2015 Should I put a bead just on the cut inside the hole of a bead on the outside of the tank or inside the tank? -John Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted December 17, 2015 Share Posted December 17, 2015 A picture would help. Quote Link to comment Share on other sites More sharing options...
jcasisa Posted December 17, 2015 Author Share Posted December 17, 2015 good idea, I will go take some in a bit! Quote Link to comment Share on other sites More sharing options...
jcasisa Posted December 17, 2015 Author Share Posted December 17, 2015 Ty, Thanks for asking for pictures because as I was taking the overflow apart to take them I realized that I did not have the gaskets in the right order! Shows mw the quality of the bulkheads because I think it should have leaked a lot more than it did. I did put bead of silicone inside the hole so that there is less play in the bulkhead but I think now that the gaskets are in the right order I wont have any issues. Once my siphon stopper return gets here I will have the plumbing complete and do the final fitting. Then it is on to the sump. That should be the final part before I start buying stuff to put into the aquarium 1 Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted December 17, 2015 Share Posted December 17, 2015 Glad I could be of indirect assistance. [emoji41] I would let the silicone dry a bit after the water test so it doesn't leach any chemicals into the tank. I'm not sure if it's in direct contact with any tank water or not. Typically a week is the safest bet. Quote Link to comment Share on other sites More sharing options...
