very nice, and since you used glass baffles you should not have expansion problems.
Can you fill us in on the silicone you chose to use? I am going to be assembling one of these soon, and have seen many people use the RTV108, but wanted to see what you recommend? Looking forward to seeing more of your DIY projects.....
Yep, its pure silicone. I got from Ace hardware. It has no algacide in it. The key to buying silicone is ensure beyond doubt that there is no added chemicals for mold or discoloration.
