So I learned something today. I had this great idea that I was going to caulk in between the baffles of my bubble trap with a piece of aquarium tubing attached to the tip of a caulking gun..... great in theory, disastrous in application. I then decided that I could goop caulk on my pointer finger and smear the seams with the caulk, this too proved less than sucessful due to the size of my hands and the 1.25 inch gap between baffles. I have now resigned to the idea of gooping caulk on all contact sides of the baffle before insertion and then caulking the sides exposed to me, making sure to still caulk all the way around the baffle at least on one side. I am on my middle baffle now and need to let the caulk dry so I can remove the supports holding it up off the bottom of the tank...... My new motto is "to hell with the mess, I have a razor scraper!!"
