I thought about siliconing my rock arrangment together in one of our African tanks.. BUT my husband did the "roll eye thing", because this particular tank I always seem to pick holes at with each way I set it up, so husband refuses to silicone the arrangment till I am content, the fish in this particular tank must get driven mad by me :lol:
So in short, make sure you like it before you silicone it
I also have the bubble wall thing in one of my tanks, BUT I am wondering whether I actually need it, it does look nice but it never runs even, always seem to get a burst of really large bubbles now and then and it makes this plopping noise (which isnt so bad, unless you are watching a good movie) :lol: The bubble bars are pretty good at keeping away build up tho to a certain extent, but a good power head is always good.
Keep those pics coming
