I need help with glue, gel, epoxy for sump.

InDahOcean · Jul 25, 2016

So I'm building a sump. I want to glue my baffles in first before silicone them. So what glue, gel, epoxy that are safe for reef that I can get at like my local supermarket (Walmart, etc.)? I'm kinda in a rush, and Home Depot and other stores are close right now (and I don't want to buy glue online and wait to ship). Only Walmart and other market are open. So are there any glue, gel, epoxy brand that is reef safe I can get at like Walmart or other big markets?

Yes, I wasn't able to respond last night. I believe it is weld on 16, or something like that. Blue tube.

I picked up the Bondic plastic welder for both securing corals and welding tubing, along with other aquarium materials. I've been pretty impressed, as the welder creates a semi-flexible, silicone like seal when used. It works wonders for securing corals and saves a lot of time standing, holding a coral in place for 5-10 minutes until the glue/epoxy starts to cure. It works more like the instrument a dentist uses to set a filling, than it does an actual welder. One end of the Bondic houses a gel not unlike super glue. This end has a thin, moderately long tip for getting the gel into tight places. The other end is simply an LED/UV diode. When the UV light hits the gel, it hardens and sets within a few seconds. The trickiest part of using the device is ensuring that some glue is out, where it can be exposed to light. If it's all covered up by something, the reaction cannot take place. Just hitting some of the glue with light does the trick and the reaction spreads across the entire surface of the glue.

For corals I just use BSI or two little fishes glue, it works fine. Its thick, and usually hardens with a little moving around to get water into it within a minute or so.
