I removed some of my zip ties, the ones that were easily accessible or obviously visible and those that interfered with siliconing it in place. But many are in place still. I would keep ones on heavy rocks and those with very little contact to the foam, but everything is relative.
I also used a ton of silicone, almost a full tube on the back wall and one side of a 10g tank. At least it felt like a ton. But everything is holding just fine.
Now i have a question or two. Do i need to let the foam cure or is it my silicone that i need to let really cure? And roughly how long? Would having water in it already slow that down? I had the foam done for a few days before siliconing it in place, and let that sit for 24h+ before adding water, but i don't think that was long enough...
