Acrylic Sump Patching holes

[NeuroticAquatics]

I'm trying to combine two acrylic sumps and have extra holes that will not be needed (from the previous configuration). I know that I can just plug holes by capping off bulkheads, but could I use pieces of acrylic on each side of the holes and attach with Weld-On 3?

if the piece of acrylic is large enough, only one piece is needed. 2 is overkill, but if you have it why not. Weldon 3 will work perfect for this.

I’d rather have overkill with a 110g.

Be sure you clean the sump surface really well. Also be sure the surface is flat. Number 3 or 4 will not fill in gaps.

if it is used, it may not be flat in which case your success with solvents may not be that great. I would suggest using weldon 16. Its the consistency of... umm, warm honey? cut a piece slightly larger than the hole, spread a bead of 16 around the patch and smack it on there. If it is vertical you may need to tape it in place until it dries. And like lapin said.. make sure it is clean and dry.

I got some 16 on the way. Thanks for the feedback!

Will work great with 16. This is probably obvious but I would recommend putting the welds on the inside so water pressure pushes the patch against the sump.

I’m planning on doing both sides of the holes just to be safe.

You’ll be fine I’ve done it and it’s been holding for years. I only did the inside.
