The commercial aptasia products work great but are usually very similar to kalc paste. They usually add vinegar and/or some sort of 'food' to keep the kalc in suspension and to make the product more paletteable. I've always gone after the large ones with kalc paste and let peppermints do the rest. Copperbands are great if you can keep them alive. They have a very high mortality rate.

I am not an engineer, but you should have no issues with a tank unless the house has issues supporting itself. Remember, you are spreading the weight across 12 sq-ft. The tank setup is going to weigh in around 1000 lbs. That is the equivalent of four 250 lb. people standing next to each other. Houses are designed to handle that, easily. They can do that while supporting the walls, roof, ceiling, etc. So, unless there is something wrong with the house structurally, you shouldn't have to worry. ps: This same logic holds true for apartments and second floors.

Patience, and no chemicals. It will be better in the long run. Small consistent water changes also help.

The bulbs fit in the same socket but you have to have the correct ballast to drive the bulb.

GlassCages also uses a Dow Corning product but they buy it in bulk containers From everything I have read and all of the people and companies I have talked to, any silicone will work. You just want to make sure it is 100% silicone and follow the directions for proper cure time. Of course, this is for glass to glass adhesion.

Yes, please tell us more. I have read lots of discussions about the best silicone to use for glass. What did you use? What do you recommend?
