Just dropped it by accident. Now it has a crack but no leak so far.
What kind of glue that i should use to prevent a leak in future.

Thanks

Your best best would be aquarium safe silicone. I used super glue gel for a crack on a turkey baster/feeder and that did the job too.

Silicone won't adhere to that acrylic tube for any length of time. If it can be done, I would think Weld-On would be the only thing that might repair that. I have never repaired a crack that large, but maybe some of the acrylic gurus around here will chime in. I wouldn't waste my time with silicone though.

My thoughts as well, but I also do not have experience using it on such a large crack.

I wouldn't recommend silicone either. Weldon would be what I would use if it were my reactor. The Weldon 16 has a thicker consistency so I think that would be the easiest fix. Good luck!

Liqid Weld-On will do the trick. Fixed an eshopps skimmer which was much worse and it has been running for 2 years w/o issue. I forget exactly which weld on, but it is the thinnest and the capillary action will draw the solvent into the crack and be VERY strong.
